The APS series inductive proximity sensors are IP67-rated rectangular compact dc sensors in top- or front-sensing models with 2.5 mm and 4 mm sensing ranges. Available in two- or three-wire configurations, the 10-30-Vdc high-frequency oscillation-type sensors are fitted with polycarbonate unshielded housings and LED status indicators. The series is available with normally open or normally closed NPN, normally open PNP or normally open NPN/PNP outputs. These sensors have an embedded 2-m connection cable. The sensors are UL-listed, CE-marked and RoHS-compliant.
