Twidec1 Pair 020M Indoor Wall Mounted Photoelectric Beam Sensor NPN NO 18mm Photoelectric Sensor Switch Proximity Switch 2m line Length with Infrared Ray Beam E3F20DNL18

Photoelectric Switch control by infraredray, as a apporach sensor, includeing a transmitter and receiver in it. A retroreflective arrangement places the transmitter and receiver at the same location and uses a reflector to bounce the light beam back from the transmitter to the receiver. An object is sensed when the beam is interrupted and fails to reach the receiver. Can be applied in security system, manufacturing industry.   Weatherproof (IP66) construction for indoor/outdoor usage.Safety sensor for garage doors or outdoor gates,Overhead door security sensor,Industrial automation, Detect small objects on manufacturing line,Entry detection for store fronts,Assist in measuring parking distance,Alarm sensor etc..
