Product Name : PJ-1030 U type photo interrupter sensor for position detection
Photoelectric switch is the abbreviation of photoelectric proximity switch. It USES the occlusion or reflection of the detected object to the light beam, and is connected to the circuit by the synchronous loop, so as to detect the presence or absence of the object.Objects are not limited to metal, and all objects that reflect (or block) light can be detected.The photoelectric switch converts the input current on the transmitter into a light signal, and the receiver then detects the target object according to the intensity or absence of the light received.
