ifm electronic Inductive Barrel-Style Proximity Sensor, M5 x 0.5, 1.5 mm Detection, PNP Output, 10 → 30 V dc,

Inductive sensors are nowadays indispensable for industrial usage. As compared to mechanical switches they offer almost ideal conditions: non-contact operation free from any wear and tear, high switching frequencies and accuracy. In addition, they are insensitive to vibration, dust and moisture. Inductive sensors detect all metals without contact.

Metal housing (cable device = V2A; plug device = brass, nickel-plated)
Switching distance 0.8 mm (b), embeddable
Output function NO
Connection via cable or plug and socket interface
