Photoelectric Sensor Wiring Through-Beam sensors have two separate devices: - The emitter - The receiver The emitter is what sends the light out and the receiver is what catches the light. Both of these sensor devices will need to be connected to 24-volt DC power. The receiver will also be connected to the 24-volt DC “Motor Starter” coil. Watch the video and type down the correct answer in the comments below: The photoelectric sensor Brown wire is always connected to: a) The load b) 24VDC Return
