A Photoelectric Sensor consists primarily of an Emitter for emitting light and a Receiver for receiving light . When emitted light is interrupted or reflected by the sensing object, it changes the amount of light that arrives at the Receiver. The Receiver detects this change and converts it to an electrical output. Specification: Type : Small and light (old) type Sensing type : Retroreflective Sensing distance: 1 m Power supply: 12 - 24 VDC Operation mode: Dark ON Control output : NPN Package includes: 1 x AUTONICS Photo Sensor BM1M-MDT Facebook Instagram Pinterest
