Photoelectrics Through-beam, Relay Output Type PC50CNT20R. • Range: 20 m • Adjustable sensitivity • Modulated, infrared light • Supply voltage: 12 to 240 VDC and 24 to 240 VAC, 50/60 Hz • Output: Relay 3 A, 30 VDC, 240 VAC • Make and break switching function • LED-indication for output ON, signal stability and supply ON • Excellent EMC Product Description Ordering Key PC50CNT20RP The PC50CNT. is a family of general purpose through- beam sensors in a compact square 17 x 50 x 50 mm rein- forced RC/ABS-housing. They are useful in applications where basic sensors provide adequate sensing perfor- mance. The long sensing range together with sensitivity adjustment gives a very flexi- ble sensor. Light and dark operation is switch selectable.
