CGU sensors place the emitter and receiver on opposite sides of a slot, providing through-beam detection without aligning separate housings. The listed models use modulated infrared LED light, a 10-30VDC supply and a red operation indicator. Choose the nominal sensing span, output circuit and switching state together. Response time is below 1ms and enclosure protection is IP65.
