IFM Electronic IF5937 inductive proximity sensor with white bronze coated brass housing, orange PBT active face. The IFK2007-FRKG/M/2LED/US-104-IRF sensor features DC PNP/NPN electrical design. It provides overload and pulsed short-circuit protection. The sensor is indispensable for industrial usage. As compared to mechanical switches they offer almost ideal conditions such as 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.
