Photoelectric switch Principle of photoeletric switch
The working principle of the photoelectric switch is that when the beam emitted by the emitter is blocked or partly reflected by the object, the beam by the emitter is blocked or partly reflected by the object, the beam receiver whereby makes a judgment and reacts.
