G18-3B5PC Retroreflective Type Photoelectric Sensor Photocell Sensor Metal Type

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

Retroreflective type photoelectric switch also integrates the transmitter and the receiver.Its dfference from other models is that reflector is used to reflect light to the photolectric switch Though the object between the photoletric switch and reflector can reflect the ight, it is much less efficient than the reflector so as to cut down reflected light.
