What are photoelectric switch sensors and proximity switches, and in what industries are they used?

Photoelectric switch sensor is a kind of sensor that uses photoelectric effect to detect. It works by sending out a beam of light and detecting whether the beam is blocked to determine the presence and state of the object. The specific process is as follows: 1. Emission beam: The sensor emits a beam of light. 2. Received signal: When an object enters the light path, the light will be blocked or scattered, and the light signal received by the sensor will change. 3. Signal processing: The sensor processes the received signal to determine whether the object exists, the position and status of the object and other information. According to the detection method, it can be divided into diffuse type, reflector type, mirror reflection type, trough type photoelectric switch and. Optical fiber type photoelectric switch

The antibeam type consists of a transmitter and a receiver, which are separated from each other in structure, and will produce a switching signal change when the beam is interrupted, typically in a way that photoelectric switches located on the same axis can be separated from each other up to 50 meters.

Photoelectric switch sensor is mainly suitable for the need to determine the existence of objects, object location and status of the occasion, such as automatic mechanical equipment in the material detection, the assembly line in the item count, vending machine in the commodity detection, but also widely used in security monitoring, traffic lights, game equipment and other fields.
