Photoelectrics Through-beam, Transistor Output Type PC50CNT20B. • Range: 20 m • Adjustable sensitivity • Modulated, infrared light • Supply voltage: 10 to 30 VDC • Output: 200 mA, NPN or PNP selectable • Make and break switching function • LED for output indication, signal stability and power ON • Protection: reverse polarity, short circuit, transients • Cable and plug versions • Excellent EMC Product Description Ordering Key PC50CNT20BAM1 The PC50CNT. is a family of general purpose through-beam sensors in a compact square 17 x 50 x 50 mm reinforced PC/ABS-housing. They are useful in applications where basic sensors provide ade- quatesensingperformance. The long sensing range together with sensitivity ad- justment gives a very flexible sensor. The DC types are with a transistor output and the configuration is fully pro- grammable (NPN, PNP, NO and NC).
