20 Hammond. Enclosures for your equipment Virtually, every electrical or electronic equipment, even amateur one, needs enclosure. Why? After all, enclosure is not always necessary for the proper operation of the equipment. There may be multiple reasons for that. Two, most common ones include: protection of users against electrical shock and widely understood protection of the equipment against influence of environment in which such equipment operates.

EDITORIAL Sharing success By Ken Millar Senior Sales Channel Manager – Europe Microchip Technology Inc. The trouble with working in a high-tech industry is that the focus is almost exclusively on the latest technologies and components. Short-termism is endemic and components are made obsolete with barely a thought for the impact that this has on the customers who designed them in just a few years ago. Microchip’s approach is a little different because, even though we shipped our 10 billionth PIC® microcontroller in 2011, we have never made a part obsolete whilst there was a customer out there who is still using it. Our production lines still produce the PIC16C54/55, which were among the first microcontrollers to be manufactured, whilst our recent acquisition of SST has provided us with the 8051/80C51 family, which preceded PIC® technology. These legacy parts are manufactured next to our latest, state-of-the-art microcontrollers, analogue and memory devices. Continuity and innovation For Microchip, continuity is as important as innovation and supporting our customers’ procurement teams is as important as the support we give to their engineers. Every aspect of Microchip’s business shares a single goal: To help our customers to succeed. For buyers, we do this by ensuring that we make it as easy as possible to buy Microchip components and that we achieve lead-times which are the shortest in the industry.
EMBEDDED SYSTEMS Microchip expands general-purpose 8-bit PIC® microcontroller portfolio with increased intelligent analogue Microchip announces the an expansion to the PIC16F75X family of 8-bit microcontrollers (MCUs) featuring intelligent analogue and core-independent peripherals, making them ideal for general-purpose applications, as well as power supplies, battery charging, LED lighting, power management and power control/smart energy applications. The new PIC16F753 MCU builds on the success of the popular PIC12F752.
DAC, capture/compare PWM modules, high-performance comparators, and two 50 mA-capable I/Os, enabling engineers to increase overall system capabilities and reduce costs.
The PIC16F753 offers all the key features of the PIC12F752, such as the integrated Complementary Output Generator (COG) peripheral that provides non-overlapping, complementary waveforms for inputs such as comparators and Pulse Width Modulation (PWM) peripherals, while enabling dead-band control, auto shutdown, auto reset, phase control and blanking control. Additionally, the PIC16F753 offers an Op Amp with 3 MHz of Gain Bandwidth Product (GBWP), and a slope compensation circuit to help in Switch Mode Power Supply (SMPS) applications. The new also MCU features 3.5 KB of self read-write programme memory, 128B of RAM, an on-chip 10-bit ADC, 9-bit
for incorporating intelligence into numerous automotive, consumer, commercial or industrial applications, where it enables a smart system infrastructure with increased efficiencies, reduced costs and an enhanced user experience.
View a brief presentation here: www.microchip.com/get/AM5D The PIC16F753 MCU enables efficient power conversion for applications such as LED lighting and power control. It also provides a versatile platform
Prioritised leadtimes The fact that we have our own manufacturing facilities, rather than out-sourcing production to third-party fabs, is crucial because it gives us complete control over our production processes. It enables us to prioritise lead-times more effectively and to have redundancy in our capacity which means that output can be increased or even doubled at very short notice. Multi-model indirect supply-chain Another important factor in our ability to help customers to succeed is in mixing direct and indirect sales channels. Our indirect sales channel combines global broadline distributors and regional narrowline specialists with internet-based distribution houses. Customers can choose whether to engage face-to-face with a distributor and or to buy components quickly and easily over the internet. Direct sales and support Microchip was one of the first silicon manufacturers to extend the direct supply channel beyond Tier 1 OEMs by introducing microchipDIRECT. Initially offering an online procurement process, microchipDIRECT is used by customers of all sizes, from credit-card users to major multi-nationals, to order samples, production volumes and device programming, as well as to schedule deliveries and to manage buffer stocks for high-volume orders. Global support network It is not just engineers who have technical questions, so Microchip provides buyers with 24/7 online support. Our support teams are based worldwide, in Europe, India and North America, and achieve response times which we believe are among the best in the business. Technical forums and blogs also give buyers access to a global community of Microchip customers. This global approach extends to our support for customers who decide to move their own manufacturing off-shore. Philosophically and culturally, Microchip is geared to be a global organisation. As such we actively help customers to migrate production to off-shore locations rather than take a more protectionist approach which would seek to keep the revenue in the same local business unit. Conclusion Although we can’t do much about economic climate, we can work with customers, directly and indirectly, to realise our inherent corporate philosophy that we are here to help every one of our customers to succeed. n
The PIC16F753 is supported by Microchip’s standard suite of worldclass development tools, including the PICDEM™ Lab Development Kit (DM163045) priced at $134.99; the PICkit™ 3 (PG164130) at $44.95; and the PICkit Low PinCount Demo Board (DM164130-9) at $25.99.

Seven essential Raspberry Pi projects Seven projects for the Raspberry Pi that range from educational to fun via highly useful. This is by no means an attempt at a definitive list and the term essential is somewhat subjective, but if you're stuck for something new to do with your Raspberry Pi there may be some ideas here! 1. Have fun with LEDs LED light chaser project (© SK Pang Electronics Ltd)
is currently being recorded, music is playing or some other useful information. There are a number of different ways that a display can be interfaced with a Raspberry Pi, and a detailed example by Mikey Sklar shows how to directly drive a 16×2 LCD. 3. Build an energy monitoring server Emoncms (© OpenEnergyMonitor, GFDL)
For many their first Raspberry Pi hardware project will involve blinking an LED, but how about controlling 8 or 16 LEDs via a port expander IC. This will provide a gentle introduction to expanding the Raspberry Pi via the I2C bus, and if you were to use a bar graph LED array it could come in handy for more complex projects where you need to indicate the level of something such as temperature or sound etc. 2. Drive a liquid crystal display Directly attaching a liquid crystal display to a Raspberry Pi (© Mikey Sklar, CC BY-SA 3.0)
Michael Kellett suggests that the Pi-Face may not be suitable for directly switching mains, and you should always check the voltage and current rating of equipment before use and ensure that it is suitably enclosed, earthed where neccessary and fused etc. Alternatively, Pi-Face and similar expansion boards could be used to control additional switching hardware that is rated for mains, e.g. relay, contactor or triac-based. The OpenEnergyMonitor project are developing “a fully open-source energy monitoring and control system that is suitable for domestic and industrial application”. Providing designs for monitoring and display hardware along with accompanying firmware and a web application for processing, logging and visualising data. The project provide instructions for setting up the Emoncms web application on a Raspberry Pi, which makes for an ideal energy-efficient web server. 4. Automate your home Pi-Face (© University of Manchester)
Given the low cost and small form factor of the Raspberry Pi and that it runs Linux, it is finding use as a tiny server in applications such as a PVR, music player and NAS. What better way to extend such a setup than with a compact display that indicates what TV show
EP&Dee | June, 2013 | www.epd-ee.eu
Add-on hardware such as the Pi-Face allows you to control heavier loads such as lights and motors and can be used to enable the creation of a Raspberry Pi-based home automation system. With lights and appliances [see below] being controlled remotely, according to a schedule, when certain sensors are activated, or perhaps in response to energy consumption.
5. Experiment with interesting sensors The TinkerKit Accelerometer Module

iC-MHL200: 12 bit universal magnetic position encoder The iC-MHL200 is an integrated system solution for linear and angular magnetic encoder applications. Combined with a target like a magnetic tape or pole wheel an universal and rugged linear or angular incremental encoder can be realized. The chip housed in a TSSOP20 package includes a linear Hall sensor array which is adapted to the targets’ magnetic pole pitch of 2 mm. The internal signal amplification control compensates for deviations of the sensor signals due to temperature and working gap variations. Incremental (AB quadrature and Z index, 12 bit) and commutating signals (UVW) are provided at the RS422 compatible line driver outputs. An external reference signal can be used to gate the internal index Z signal to provide an absolute zero pulse. The linear resolu-
tion is configurable up to 4096 steps per each magnetic signal period of 4 mm, which corresponds to an incremental linear displacement of less than 1 micron. At the fastest incremental output frequency of 8 MHz, linear movements of up to 8 m/s can be tracked with full 12 bit resolution. The UVW commutation signals are
available for two- and four pole linear motor configuration. iC-MHL200 is typically used in industrial, automotive, and medical applications, such as: • Position control and acquisition • Linear / rotary speed control • Motor control • As substitute for optical incremental encoders. A synchronous serial SSI / bidirectional BiSS-C interface provides additional serial data output. Using BiSS-C allows for setting device configuration. These settings can be permanently stored in an OTP-ROM. iC-MHL200 operates from a supply voltage of +5V (±10%) within an operating temperature range of -40 to +125°C. iC-Haus www.ichaus.com/product/iC-MHL200

First CAN FD plug-fest In the first CAN FD plug-fest, Bosch, Peak, and Vector proofed the interoperability of their CAN FD implementations. The FPGAs implementing the CAN FD data link layer as submitted for international standardization were tested using different network topologies and transmission speeds. All nodes used a 40-MHz
The CAN FD nodes tested on interoperability in CiA’s laboratory used different off-theshelf CAN high-speed transceivers by NXP
clock frequency, an arbitration bit-rate of 500 kbit/s sampled at 80 percent and a data-phase bit-rate of 4 Mbit/s sampled at 60 percent. The tests were performed with different busloads up to 100 percent. The three nodes communicated in bus-line (9 m) and passive star topologies (2 × 3 m and 1 × 6 m). The passive star was terminated with 60 Ohm at the center point. The next CAN FD plug-fest will take place in September. Parties interested in participation may contact CiA office. CiA plans a permanent CAN FD test environment for interoperability tests. The CiA working group specifying CAN FD device and system design recommendations proposes a ration of 1:8 for arbitration/dataphase speed. In addition, the group will recommend bit-timings for different topologies as well as configuration registers for the CAN FD protocol controllers. CAN FD implementations should be clocked by 80, 40, or 20MHz in order to minimize timing problems. CiA

Platforms to consider for Motor Control and Robotics Applications by Joe Alderson, Technical Marketing Engineer, Farnell element14
From automobile assembly and PCB fabrication, to consumer electronics, robotics is home to some of the most exciting engineering taking place today. Learning about robotics, whether you are an experienced engineer or complete beginner, has never been easier thanks to the application notes, software examples and tutorials available online today. The element14 Community, is an encyclopaedic library of information for electronics design engineers and robotics is one of its key technologies. Whatever your preferred embedded platform, be it AVR, PIC or 32-bit ARM, element14 supports a wide range of development boards. This article gives you an overview into some of the most popular boards for motor control and robotics applications. The Sitara AM3359 ARM Cortex-A8 processor in the newly released BeagleBone Black provides a 1 GHz platform ideal for robotics development. Although the BeagleBone is a “bare bones” version of the BeagleBoard, it
features dual 46-pin headers and plenty of industrial communications capability, along with a new addition of HDMI. The BeagleBone Black is much cheaper than the original version and includes Ångström Linux as standard, making it perfect for high-end robotics applications. It even has 512 MB of DDR3 RAM to support most demanding programs. The BeagleBone Black is capable of not just interfacing to all robotics motor drivers, location or pressure sensors and 2D or 3D cameras, but also running OpenCV, OpenNI and other image collection and analysis software to recognize the objects around robots and the gestures made to control it. BeagleBone Black is supported with a strong community and is fully open-source, meaning you can utilise its design – if you can get to grips with laying out a BGA package. Whilst not quite as fast as the BeagleBone Black and featuring an different ARM1176JZ-F Applications Processor, the Raspberry Pi can be used to control a robot or even use a GPS module and USB camera to build an intelligent guidance system for it. With the wide range of expansion boards available for the Raspberry Pi, you can offload many low level tasks to smaller controllers, leaving the main control unit free to focus purely on data processing and task delegation. In the one year that Raspberry Pi has been available, there have been a large number of

robotics applications from around the world, including using the Raspberry Pi to control drones. The Raspberry Pi is also great as a learning tool and boards such as the
Gertboard and PiFace Digital are designed to teach motor control and basic robotics. For teaching in schools, the Raspbian operating system makes robotics accessible, whilst the hardware on the Raspberry Pi provides enough GPIO access to make it useful for all but the most demanding robotics projects. If your robotics project does not require high end Cortex-A series applications processors, and let’s face it, that is probably the case, there are several other options. The Freescale Kinetis Freedom Platform, including the FRDM-KL05Z, FRDM-KL25Z and FRDMK20D50S boards provide a Cortex-M0+ / Cortex-M4 solution for robotics.
You need two PWM channels to run two motors at different speeds, two to three channels to send 10 μs trigger pulse for Ultrasonic sensors and three to five channels to capture the return pulses from Ultrasonic sensors.
Freescale's Robot Kit that operates with the Tower System Mechatronics Board is an easyto-use mechatronics development and demonstration platform. This toolset allows for the science of combining mechanics, electronics, and software into an integrated system. The Microchip PIC16F684 can be used to create an inverted pendulum robot. By implement-
ing a positional Proportional-Integral-Derivative (PID) feedback control with the PIC16F684 can be used in an inherently unstable system. An inverted pendulum is used to demonstrate this type of control. The inverted pendulum consists of three main parts: the base platform, the pendulum and the controller board. Although this demonstrates the capabilities of PIC MCUs in simple control systems, PIC32 MCUs are capable of delivering complex robotics control systems. Microchip provide a wide range of software support which is extremely useful in robotics development. Finally, for a great introduction to the world of robotics, Arduino provides a wide range of boards. From the 8-bit Atmega328 on the Arduino Uno to the 32-bit SAM3X8E CortexM3 on the Due, Arduino provides a massive selection of software examples and an accessible IDE in an open-source model. The Arduino approach of good design and simplicity has
led to its popularity in robotics. The challenge of utilising 8-bit AVR MCUs for tasks which you might ordinarily turn to a 32-bit processor for can be rewarding and enlightening.
Some of the development boards for the above robot designs can be designed and created using CadSoft EAGLE. CadSoft recently brought out a new version of its design software EAGLE 6.4 featuring new interoperability features and improved design simulation. All these products can be researched, discussed, bought and supported from bought from www.element14.com n

Ambient LED Lighting Advances in Tomorrow’s Vehicle The advancement of Ambient LED Lighting solutions stems from the quest by automotive-OEM interior stylists to add value and make their vehicles more appealing to the driver’s senses, while creating a truly positive driving experience and increasing brand awareness. Electronics continues to be the fastest-growing sector of automotive content, over mechanical, pneumatics and hydraulics. With the increasing number of ambient LED applications - from cluster backlighting to cupholder lights, to map lights, to mood lighting in footwells and door trims, to dome lights - ambient LED solutions, both white and RGB, are differentiators used by automotive OEMs. In fact, research indicates that lighting can enhance the driver’s visual senses. It remains critical to select the right embedded solution to match the application requirements and enable cost-effective designs with a shorter time to market. This article will take a closer look at: • the tradeoffs among the methods for controlling LED ambient lighting solutions • the use of control algorithms to enable effective binning, dimming and temperature compensation for LED color • creating driver-preferred lighting scenarios by changing the color and brightness of the LED arrays by Johann Stelzer / Andreas Reiter / Frank Ziegenhorn Microchip Technology Inc. With the ever-increasing need for networked lighting modules, implementing the best practices for LIN communications in ambient LED lighting solutions can help reduce development costs and cycle times. Because LEDs consume less energy and occupy less space, fuel efficiency is enhanced and the packaging benefits allow stylists to expand their creativity in using lighting to enhance the cabin. Overall, ambient LED lighting solutions provide OEMs with an opportunity to innovate a comforting atmosphere for both the driver and passenger. Ambient LED lighting is far more than a gimmick feature. Research on the impacts of interior lighting has widely been ignored in the past few years, while the R&D focus has been on exterior lighting. This is changing. With the
EP&Dee | June, 2013 | www.epd-ee.eu
rapid advancement of LED technology in the past few years, OEMs are in the position to offer not only more colorful interior lighting but also user-adjustable lighting. Drivers are then able to adjust lighting to their mood or taste. Additionally, there is much more potential in interior lighting. In future car models, interior lighting is poised to become part of the advanced driver information system. The revolutionary idea is to adapt the interior light according to the driving situation. The interior light color could be different for the city, rural roads and highways, for example. Red interior light can increase the driver alertness in the city, while a yellow interior light can help the driver to relax when cruising on a highway. Interior lighting could even warn the driver about an imminent acci-
dent. In many cases, flicker-free interior lighting is associated with a high-value proposition for car makers to differentiate their product in an ever-increasing competitive environment. Driving the LEDs LEDs must be driven with a source of constant current. Most LEDs have a specified current level that will achieve the maximum brightness for that LED without premature failures. The light output from a LED is proportional to the current passing through it. There are two techniques to control the LED brightness in the circuit. One is to vary the LED drive current. The LED drive current may be controlled using a variable resistor or by using a variable-voltage power supply. Another technique is to apply pulse-width modulation (PWM) or variable-
DESIGN frequency, fixed-duty-cycle PWMs to the LED drive current. The first method has two major disadvantages: As the current is reduced, the LED efficiency may also be reduced. And, in high-power white LEDs, a color shift may take place with the reduction in current level. The PWM dimming technique always drives the LED at full current. Therefore, problems such as reduced efficiency and color shifts can be eliminated. To create different color combinations, the duty cycles of the PWM outputs will have to change over time. Color Control Methods Embedded microcontroller technology allows the color components of a light source to be sensed and actively controlled. Active color control can be used to create a specific color of light, or can be used to create a mix. For example, multiple component colors can be blended to create a specific quality of white light.
LEDs cally requires a resolution of 14-bit to 16-bit and a quite powerful microcontroller (MCU). The same quality can be achieved with four channels, each with 10-bit resolution, which is typically found in a low-cost 8-bit MCU. In this four-channel scenario, color x brightness multiplication occurs in an external hardware circuit. The typical logarithmic gradation required for brightness control can also be realized in a sufficiently precise manner on such a low cost 8bit MCU, with approximation via a power function (see Figure 1). LED temperature is one of the factors that have a significant impact on the LED’s color. Hence, temperature has to be compensated. A simple, effective and cost-efficient method for temperature compensation is to use a microcontroller’s on-chip comparator and a lowcost Negative Temperature Coefficient (NTC) thermistor that is positioned close to the LEDs. Another way of gaining control over the LED’s temperature is by measuring its forward volt-
microcontroller, such as a PIC® MCU with nonvolatile memory, inevitable. Furthermore, the need to network those RGB lighting nodes in the vehicle, along with the desire for diagnostics, calls for a suitable low-cost communication protocol. While the first generations of interior lighting were individually wired, the latest generations and recent developments at OEMs make use of the well-known, cost-effective LIN / J2602 communication bus. The LIN communication speed of 19.2k baud is sufficient to support color changing and lighting scenarios without noticeable impact for the driver and passengers. More recently, LIN communication with autoaddressing capability is being considered for this type of application by some car makers. There are several known auto-addressing methods, each with pros and cons (see Figure 2). Common to all of them is that they add costs to the silicon, when compared with standard LIN communication. However, those addition-
Figure 1: Block diagram showing solutions with 3 and 4 PWM channels
Figure 2: Block diagram showing LIN transceivers with and without auto addressing Using three individual color values for Red (R), Green (G) and Blue (B), plus an additional value for brightness, supports the generation of the desired color either with three PWM channels or, simpler and more effectively, by three PWM channels—one for each color— and an additional, separate fourth PWM for brightness. The latter approach can be experienced in recent Ford Motor Company models offering mood lighting. The approach that uses three channels for integrated color and brightness control typi-
age drop. The resolution of a microcontroller’s integrated 10-bit analog-to-digital converter (ADC) is sufficient for this task. The forward voltage drop measurement has its benefits, as it eliminates the need for additional external components. Lighting Networks Color correction, temperature compensation, color changing, color mixing, brightness control and the desire by car makers to realize various lighting scenarios make the usage of a
al costs yield reduced logistics costs at the OEM and Tier1 levels. Addressing Space Constraints Typical interior-lighting applications are very space constrained. Light nodes are embedded in switches, cup holders, door handles, dashboards, seats, reading lights, footwell areas and overhead consoles. Available space for the electronics is often squeezed to an area of 10 mm × 20 mm or less, driving small package solutions in SSOP, QFN and DFN housing. www.epd-ee.eu | June, 2013 | EP&Dee
Ambient temperature and self heating in such environments require careful heat management, for semiconductor devices with low power dissipation and extended operating temperature ranges from -40°C to 125°C. Usually, the nodes are connected to terminal 30 and thus require very low standby current, significantly below 100 μA. Microchip’s Automotive Ambient Interior Lighting Module Reference Design demonstrates microcontroller-based control of RGB LED devices (see www.microchip.com, Application Note AN1074). This module can be controlled remotely by a master body controller, via the LIN bus. These
troller and RGB LED. LIN commands are interpreted by the module to control color mixing (16,383 colors) and intensity (1023 levels). The kit ships with four modules to assign as lighting zones in a LIN or J2602 network. These modules can also be used in conjunction with Microchip’s LIN Serial Analyzer (Part # APGDT001) to quickly create a working LIN RGB network, straight out of the box. A microcontroller-based solution provides the flexibility and integration required for future RGB LIN-based interior lighting applications. Carefully considered system architecture designs allow the usage of low-cost 8-bit
tion and enhancing driving comfort and safety. Features such as approach sensing and capacitive-touch switches are additional functions that are easy to implement at almost no additional cost with PIC microcontrollers, thus further enhancing the value of the system.

Microchip introduces world’s first programmable USB2 controller hubs; adds simultaneous support for USB2 and HSIC, low-power modes Microchip announces the expansion of the USB2 Controller Hub (UCH2) portfolio it gained with the recent SMSC acquisition. The seven new UCH2 ICs, across three families, are the world’s first to provide programmability, enabling the developers of PCs and mobile devices to configure their designs without external memory. Additionally, these are Microchip’s first UCH2s to support both USB2 and USB High Speed Interchip (HSIC) connectivity, maximum battery life via low-power modes such as Link Power Management (LPM), and the ability to replace wall chargers with advanced battery charging modes, such as BC1.2, Apple®, SE1 and China charging. For applications that need to communicate over multiple protocols, these UCH2s feature direct I/O bridging to I2C™, SPI, UART and general-purpose I/O. They also have the flexibility to support the behaviours of multiple operating systems, such as vendor-specific messaging

and FlexConnect for simple port reversals. While the PC market is converting to USB3, most market forecasts predict that USB2 will remain predominant in mobile devices until at least 2015. This continued use of both USB3 and USB2 challenges the designers of PCs and mobile devices to ensure interoperability while providing new features and maximum battery life. Microchip’s seven new UCH2s, across three families, address these needs for both PC and mobile manufacturers. Whereas competing USB2 Controller Hubs only offer limited battery charging and require external memory for configuration, Microchip’s new UCH2s integrate “Quad Page” configuration OTP Flash memory, which reserves space for interoperability and other customisations by the designer, including four separate configuration opportunities. Additionally, Microchip makes it easy to generate configuration settings and programme the OTP memory, via its
new ProTouch Configuration Editor software tool, also announced today. The ProTouch Configuration Editor software tool is available today via a free download from www.microchip.com/get/2M4E. It is bundled with the ProLink programming software. Also being announced today is the USB2534 Eval Board (EVB-USB2534), which is available now priced at $399 each. This board supports the development of USB charging designs using the new three-member USB253X UCH2 family for mainstream USB2 applications.

Hammond. Enclosures for your equipment Virtually, every electrical or electronic equipment, even amateur one, needs enclosure. Why? After all, enclosure is not always necessary for the proper operation of the equipment. There may be multiple reasons for that. Two, most common ones include: protection of users against electrical shock and widely understood protection of the equipment against influence of environment in which such equipment operates. by Marcin Kajzler
The first important function of enclosure is to prevent from touching elements which are live and ensure that equipment is protected against direct contact. Such protection is the most basic way to ensure protection against electrical shock. If this is the only protection, then such equipment holds zero protection class. In such case, enclosure is made of nonconductive material: dielectric material. Why can’t this be a conductor? If a breakdown of any of the components happens to the conductive enclosure, it could lead to production of user’s life-threatening potential. Metal enclosure should, therefore be connected to a grounding which is usually protective conductor or protective – neutral conductor. Such equipment offers the first class of protection. In case of equipment damage, proper grounding will protect the user against voltage dangerous for their life. Enclosures connected to the grounding system, which are made of conductor, have one more advantage: they reduce electromagnetic emission of the equipment and shield it against influence of external interfering fields. The second important reason of placing appliances in enclosures is the necessity of their protection against influence of environmental conditions, including water and solid bodies

influence. The most popular system of equipment marking is a code in the IPyz form. A digit in the “y” position shows resistance to penetration by solid bodies, whereas the “z” position – shows resistance to water. A list of respective values and their meaning as per the PN EN 60529 standard are presented in the Table 1.
If a product does not require marking with any of the characteristic digits “y” or “z”, then “X” is placed instead (e.g. IP2X – no specification of water resistance). Enclosures used in special applications e.g. in equipment designed to operate in explosive conditions, require non-combustibility.

In practice, metal enclosures do not burn, and plastic ones do not burn with flame, however, they melt when exposed to high temperature. Widely available metal enclosures are practically only aluminum enclosures. Steel enclosures are most often made to customer’s individual order. Popularity of aluminum is due to its low weight, simplicity of machining and natural resistance to corrosion. In case of plastic enclosures, the selection of materials is much wider. We can choose from three basic materials: ABS, polycarbonate and polystyrene. Below, there is a description of the most popular materials used for production of electric and electronic enclosures. Such list should help while making the selection of enclosure for a given application.
metal, aluminum is very light and easy to machine, however, it is not so much resilient. It reflects electromagnetic radiation very well.
Aluminium Aluminium, when in contact with oxygen from the air is covered with a thin film of aluminum oxide. This film tightly covers the whole surface and protects against diffusion inside the layer of oxygen particles which prevents further corrosion.
Additionally, they protect against external magnetic fields because steel is ferromagnetic. Steel reflects electromagnetic radiation better than aluminum, however, it is more prone to corrosion and sensitive to acids and bases.
Steel Steel enclosures weight more, are more resilient and resistant than aluminum enclosures.
rather cheap enclosures, without any special mechanic properties. Polycarbonate Plastic with excellent mechanical properties and durability comparable with aluminum. Polycarbonate is exceptionally transparent for visible light. Since it is quite expensive material, enclosures made of it are less popular than those made of ABS.
ABS (Acrylonitrile Butadiene Styrene) ABS is a plastic material, one of the most popular materials used to make enclosures. This is a very hard material resistant to scratches and impacts, but at the same time it is susceptible to esters and acids, but also to UV radiation which might cause a change of its colour.
HM-1599TABLGY As one of the few plastics, ABS can be coated with metallic coat. Thanks to this, there is a possibility of producing ABS enclosure that will conduct current.
This phenomenon causes that aluminum enclosures virtually do not corrode thanks to which they do not have to be preserved. As a
Polystyrene This material is quite hard, but brittle. It easily Hades and its transparency leaves much to be desired. This is one of the cheapest plastics to produce that is why it is used for production of
One of the most widely known manufacturers of enclosures in the world is Canadian Hammond which was established in 1917. At the beginning of its business activity, it produced, among others, radio sets and amplifiers. Sudden increase in the popularity of electric devices in the 50’s and 60’s opened new markets. Hammond company started to produce transformers and enclosures. At present, Hammond offers many different types of enclosures which are available in all shapes and made of various materials. We can choose among enclosures designed for control panels of electronic appliances, console, for devices with displays, dust and water – resistant and many others. The list of available types of enclosures is very long. TME’s offer includes over 500 Hammond enclosures, which means that there is much to choose from. n www.tme.eu www.epd-ee.eu | June, 2013 | EP&Dee

SUYIN Optronics presents an ultra-compact mini-camera module with a resolution of 8 megapixels Suyin Optronics offers a highly miniaturized camera module bearing the part number CM 8013 AF05 OV01 that features a maximum resolution of 8 megapixels. Due to its compact dimensions of 8.5 mm (W) × 8.5 mm (L) × 5.91 mm (H), the module is also suitable for use in applications facing particularly tight space restrictions. Integrated autofocus capabilities, combined with a highperformance lens consisting of five plastic elements, ensures outstanding image quality and provides a display that is always sharp, regardless of the distance setting used. The image sensor, an OV8825 CMOS sensor in a PLCC housing, is in the 1/3.2-inch or 1/4 inch format. The size of the active image sensor area (the effective resolution) is 3,296 (H) × 2,460 (V) pixels. Using the standard “serial camera control bus” (SCCB), the images are read out as 10bit RAW RGB (MIPI) files (full-frame, sub-sampled, windowed). The user has comprehensive control over output of the image files with regard to image quality and formatting. The supported image sizes include 8 megapixels, EIS1080p, 1080p, EIS720p, EISQ 1080p, Q 1080p, EISVGA, VGA and QVGA, among others. Depending on the resolution, the maximum image transmission rate is 24fps (8 megapixels), 30fps
(EIS1080p), 60fps (EIS720p), etc. All required image editing functions – such as the exposure setting, white balance, the masking of defective pixels, etc. – can be programmed via the SCCB interface. Black level calibration is performed automatically (ABLC). Among other features, the miniature camera module offers integrated 256-byte one-time programmable (OTP) memory for stor-

surement Device in a new M2 Enclosure A supply voltage in the range of 9VDC to 36VDC is required. Typical power consumption is 1.1W. The temperature measurement range of -60°C to +1370°C is digitalized by a 24-bit analog-to-digital converter. Cold junction compensation is accomplished using a PT100 temperature sensor directly at each measurement input socket. A compensation of the AD converter is performed each time before a measurement value is acquired. To achieve the highest possible accuracy, the sensor characteristic is linearized using an internal compensation algorithm. The hardware filter used in IPETRONIK’s M-THERMO2 is a single pol low-pass RC filter with a cut-off frequency of 1 Hz. The resolution is ≤0.087°C (≥14 bits). Accuracy is specified as ±0.035% of the temperature
measurement range at 25°C. The measurement module features channel sampling rates up to 100 Hz and a maximum aggregate sampling rate of 800Hz. Status LEDs at each measurement input indicate open inputs (sensor break detection) and provide information on the channel location during software configuration. The output data is transmitted using CAN bus 2.0B according to ISO 11898-2 with up to 1 MBit/s. All measurement inputs, CAN bus and power supply are completely galvanically isolated from each other. As known from the former M-Family, M-THERMO2 provides a toolless mounting technique to attach the modules to each other. IPETRONIK www.ipetronik.com
Operating from a 2.6V to 5.5V input voltage range, the XRP6670 is capable of supplying up to 3Amps of continuous current with an adjustable output voltage as low as 0.8V. This synchronous Pulse Width Modulation (PWM) voltage regulator can accommodate a broad range of inductor and output capacitor values through its constant 300kHz to 2.5MHz programmable operating frequency. Additionally, the adjustable frequency range of the XRP6670, which is set via a single resistor, allows the user to optimize size, transient response and efficiency while precisely positioning the fundamental operating frequency and subsequent harmonics. Ideal for industrial, medical, and audio and video equipment, the XPR6670, with its compact form factor and reduced component count, is also ideal for space sensitive applications.

AUTOMATION Peratech designs the QTC Ultra Sensor â€“ an ultra-sensitive touch sensor for domestic, commercial and industrial use Peratech, the innovators in touch technology, has developed an ultra-sensitive sensor using its award winning QTCâ„˘ technology. Quantum Tunnelling Composite material changes its resistance when pressure is applied, enabling it to be used to make
pressure sensors that can respond to light touches even through steel or glass. Fitting conventional switches to products always introduces a point of possible failure either within the switch or the fitting of the switch. QTC Ultra Sensor solve this as it can either be fitted as a small piece of QTC sheeting or screen printed on the back of the steel plate as required by the product designer. The design works equally well with other materials such as plastics, glass or wood provided that there is enough flex to activate the QTC switch. It can even be used behind translucent materials
to create secret till lit buttons. QTC solutions are thinner, smaller, more discrete, less expensive and ultra-reliable as there is no air gap and no moving parts making them ideal for domestic, commercial and industrial equipment. QTC material has nanosized particles of conductive material evenly distributed in a non-conductive polymer. When a force is applied the particles move close enough for electrons to flow between the particles using an effect called Quantum Tunnelling.

New ProfiLED lightbars from OMC save cost; provide even illumination
Everlight Electronics Introduces a Cost-Effective 1W High-Power LED for Multiple Lighting Applications
OMC, the pioneer in optoelectronics - LED lighting, backlighting and industrial fibre optic transmission components – has announced the launch of its ProfiLED Lightbar™ product family, which reduce cost and offer an improved appearance, especially in low and medium volume applications. Unless production volumes are very high, the cost of developing a custom lightbar is prohibitive for most applications. Instead, designers often use several standard square or rectangular units in combination. However, this approach gives rise to high materials and assembly costs, and the finished product has unsightly dark lines where the arrays join. Using the same approach as it adopts in its ProfiLED Backlight™ range of LCD backlights, which employ LED

Everlight Adds Two IRLEDs for Remote Controls and Optical Touch Panels EVERLIGHT Electronics Co., Ltd. expands its product offering of ‘invisible’ light sources for remote control applications with two new SMD infrared LEDs (IRLEDs), the IR26-71C and the IR26-61C. The two IR26-71C models are 940nm side-view SMD IRLEDs that feature superior mechanical (height) and optical (radiant intensity and viewing angle) characteristics which make them ideal for use in remote controls and touch panels. Their height of only 1.2mm allows the target devices to be as slim as possible, even when implemented into portables like mobile phones and tablets. With a radiant intensity of 5mW/sr and 8mW/sr or more at 20mA, they outperform most SMD IRLEDs in the market. The 8.0mW/sr@20mA version catches up with or exceeds 5mm IR diodes, and allows either lower driving currents, to extend the battery lifetime of handheld
devices, or increased panel sizes respectively increased transmission distance of remote controls. A viewing angle of 50° ensures that the remote control does not need to be directly pointed towards the receiving device, but
instead provides a wide operating range. Based on a similar package design, Everlight offers the IR26-61C IRLED series with a narrower viewing angle of 20° and the PT26-71B phototransistor series, which are both matching pairs designated for smallmiddle (5-32”) size optical touch panel applications.

EVERLIGHT Unveils Ultra-small Outline ITR Photo Interrupter for Optical Switches, Digital Cameras and Printers EVERLIGHT ELECTRONICS CO., LTD. has introduced the latest member of its ITR series of photo interrupters for use in optical switches, digital cameras and printers, the ultra small outline slotted type ITR1205ST11A/TR. A slotted type opto interrupter detects an object when it enters the gap of the slotted switch and blocks the light path between the emitter and detector.
EVERLIGHT’s ITR Products consist of an infrared emitting diode and an NPN silicon phototransistor, integrated by a
double molding process. This unique process reduces 74% volume in dimension as compared with conventional photo interrupter product in the market. The phototransistor detector receives light from the IR LED only, and avoids the noise from ambient light. With a low profile of only 2.7mm, the new ITR1205ST11A/TR has an even more compact size than conventional parts. By using an advanced packaging technology, EVERLIGHT's ITR1205ST11A/TR can be designed to have a gap and slit width of 1.1mm and 0.3mm respectively, thus enabling it to have a higher degree of accuracy or detection sensitivity. This high degree of accuracy is especially needed for digital camera applications. EVERLIGHT’s ITR photo interrupters are Pb/Halogens-free and RoHS compliant. EVERLIGHT ELECTRONICS www.everlight.com
Digital differential pressure sensor for highly accurate monitoring Omron Electronic Components BV has added a new digital flow sensor offering exceptionally high accuracy and repeatability in monitoring low air flows. The sensor is an ideal alternative to a differential pressure sensor for optimising energy efficiency in air conditioning and ventilation systems, like variable air volume (VAV) and heat recovery unit systems (HRU) or for use in high quality medical equipment and industrial applications. Based on Omron's cutting-edge MEMS thermal flow sensor chip, the new Omron D6F-PH provides better accuracy and repeatability than standard differential pressure sensors especially in low flow conditions. It is capable of measuring with superior sensitivity and reproducibility in these environments and with a wider pressure range than the commonly used capacitancetype and piezoelectric-type differential pressure sensors. Embedded ASICs carry out digital correction (linearity and temperature correction) making the D6F-PH more precise and less influenced by temperature than conventional analogue output sensors.
Features of the sensor include a new digital correction algorithm that achieves 3% R.D. precision. The sensor’s flow impedance has been increased, to reduce the influence of the bypass pipe length and diameter and give more stable measurements. The D6F-PH is suitable for use in a bypass configuration where the small differential pressure generated by orifice or flow restrictor is correlated to high volumetric flow in main duct. The sensor is available from Omron in three versions, with measurement ranges from 0-250Pa, ±50Pa and ±500Pa. Current consumption is just 6mA with no load at supply voltage Vcc of 3.3VDC. The sensor features a digital I2C interface with 12 bit pre-set resolution. The new sensor is exceptionally compact, with dimensions of just 26mm × 22mm × 18mm as a result of the new flow path design. Omron’s D6F-PH digital differential pressure sensor can optionally be supplied pre-set to provide temperature measurement or failure detection functions. OMRON http://components.omron.eu
