Metal Infrared Ray Trough Beam Photoelectric Sensor

Principle of photoelectric switch
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.

Metal Infrared Ray Trough Beam Photoelectric Sensor

Description

Throuh- beam type

Through-beam type photoelectric switch is designed that via the light beam between opposite- mounted transmitter and receiver,the object passing through these two devices will interrupt the light beam and start the receiver.

Diffuse type

Diffuse reflection type photoelectric switch integrates the transmitter and the reciver.Light reflected by the photoelectric switch is rflected back to the receiver by the detected object.

Retroreflective type

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.
