These cylindrical capacitive proximity sensors use plastic housings in M12, M18 and M30 sizes. Select the sensing distance and working range together, then choose the supply and output circuit. The DC range includes NPN and PNP versions with normally open, normally closed or combined outputs, subject to the model combinations below. AC versions use a two-wire output. A red LED indicates operation.

These sensors are intended for ordinary industrial control. Nuclear, gas or power systems requiring exceptional reliability, personal-safety functions, harsh outdoor or contaminated environments, fire or explosion hazards, military use and aerospace require a specifically designed and confirmed configuration.
