Detection objects are not limited to metal, and all objects that reflect light (or block light) can be detected.
Photoelectric switch makes use of the block or reflection of the detected object to the light beam, and the circuit is turned on by the synchronous circuit to detect the presence or absence of the object.
The photoelectric switch converts the input current into a light signal on the transmitter, and the receiver detects the target object according to the intensity or presence of the received light.
Built-in multiple protection circuits, strong anti-interference ability, sensitive response.
The sensor uses infrared light to detect the objects for sensitive detection with delay that can be almost ignored.
