M12 inductive proximity sensor P1-12.20.K

Sn=5.0mm, 4-wire, NPN/NO+NC, 10-30VDC, 250mA, M12x45mm

Price 24.96 EUR no VAT

Unshielded type P1-12.20.K proximity inductive sensor for direct current with cylindrical plastic housing M12x45mm, with NPN output type, with one normally open and one normally closed contact. The maximum distance of operation of the proximity sensor is 5,0mm. The sensor ends with a 4-wire PVC connecting cable with a length of 2m and has an LED indicator showing the output state of the inductive sensor. The sensor's outputs are protected of overload and short circuit.


The presented unshielded type M12 inductive proximity sensor is used in industrial systems, as automation equipment for switching at 3- and 4-wire direct current electrical circuits. It is activated by approaching of metallic object to him active area. The inductive proximity sensor is resistant to moisture and dust. It has a long service life thanks to the non-contact switching of the electrical circuit in which it is connected.
