CGY-E economy photoelectric sensors combine cylindrical threaded housings with diffuse, retro-reflective or through-beam sensing. Diffuse models detect reflected light from the target, retro-reflective models operate with a separate reflector, and through-beam models use an opposed emitter and receiver. The listed infrared models operate from 10-30VDC, with NPN or PNP outputs and IP65 protection.
