Introduction
SN-GDD-1 beam/diffused infrared photoelectric sensor consist of a pair of emitter and receiver installed face to face which compose a circuit. After power is supplied, the receiver will send out an electric signal (NPN/PNP) to the controlled equipment and system when the infrared beam form emitter is blocked by an object.

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.
