The infrared proximity switch uses the object to block or reflect the beam, and the circuit is strobed by the synchronous circuit to detect the presence or absence of the object. Objects are not limited to metal, and all objects that reflect light can be detected. The photoelectric switch converts the input current into an optical on the transmitter, and the receiver then detects the target object according to the received light intensity or presence or absence. The photoelectric switch is common in security systems is often used in the industry to count the number of movements of the robot arm.
