Feature: This Photoelectric Switch is controlled by infrared ray, as an proximity sensor switch, consists of a light emitter and a receiver. A proximity-sensing (diffused) arrangement is one in which the transmitted radiation must reflect off the object in order to reach the receiver. In this mode, an object is detected when the receiver sees the transmitted source rather than when it fails to see it. Can be applied in security system, manufacturing industry.
