>> This IP65-rated Lexium MDrive from Schneider Electric Motion is an integrated motor for machine builders to use in applications subject to tough environmental conditions. IP65 LMDs include sealed M12 industrial connectors for power, communications and I/O interface.
>>
To get the IP65 rating, a component must withstand hosing from nozzles up to 30 kPa.
IP rating’s first number: Denotes protection against solids Level Object size protected Effective against against 0 — No protection against contact and ingress of objects 1 Anything larger than 50 Any large surface of the body, such as the back mm of a hand, but no protection against deliberate contact with a body part 2 Anything larger than 12.5 Fingers or similar objects mm 3 Anything larger than 2.5 Tools, thick wires, and so on mm 4 Anything larger than 1 mm Most wires, screws, and so on 5 Dust protected Dust protected Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment, complete protection against contact (dust proof) 6 Dust tight No ingress of dust, complete protection against contact (dust tight)

What IP means for applications Now consider the two larger tables that accompany this article. A component with an IP65 rating withstands solid objects (as indicated by the 6) and liquids (as indicated by the 5). So, an IP65 motor is considered dust tight. It also seals against water projected from any direction from a distance of 3 m through 6.3-mm waterjet nozzles for a duration of at least 3 min with pressure not exceeding 30 kPa. Could the authors of this technical specification be any more specific? Probably not. But after reviewing application needs, how does an engineer decide if IP65 is an adequate protection level? To begin, the engineer must consider if the motor will be used outdoors or need to be fully submerged. Also: Will it need to withstand washdown conditions?
