Photoelectric proximity sensors SICK’s PowerProx MultiTask photoelectric sensors combine the advantages of time-of-flight technology in a small housing with increased detection speed. Objects being conveyed at high speed, small and flat objects, jet-black and shiny objects can be reliably detected over an extensive sensing range. The photoelectric sensor provides stable detection results over a large detection angle and is immune to ambient light. Sensing ranges are available from 5 cm to 3.8 m. The sensor provides eye safety at the level of laser class 1 and fast signal processing, while

the VISTAL housing ensures the device is sufficiently rugged. Adjusted by means of a potentiometer or teach-in button, there are variants available with either one or two separately adjustable switching thresholds, depending on the application. IO-Link can be used to define up to eight switching points and to make use of the smart sensor functions. The four variants — distance, speed, precision and small — are designed for different detection tasks. The distance variant is suitable for occupied bay and clearance detection, pallet handling, and collision protection in storage and conveyor technology. Quick response times, high switching frequencies and reliable object detection at extended sensing ranges make the speed variant suitable for the packaging industry or in any application that relies on detection at top speed, such as highspeed counting. The precision model detects the smallest of objects, cut-outs and recesses from a considerable distance. It copes well with changes in materials and surfaces, so is suitable for quality control and for handling and assembly applications. The small variant is flexible and can be used in a wide range of different fields, offering high switching frequencies of up to 1000 Hz. SICK Pty Ltd www.sick.com.au
