4m Infrared Photoelectric Proximity Switch Optical Sensor G24-3B4PC

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.
Photoelectric Sensors detect photo-optical workpieces. USYUMO provides many varieties of Sensor, including diffuse-reflective, through-beam, retro-reflective, and distance-settable Sensors.
