The safety grating light curtain is also the photoelectric safety protection device (also known as the safety protector, high-speed punch protector, infrared safety protector, etc.). In an intelligent processing plant, people and machines work together. In some mechanical industrial equipment with potential risks, such as stamping machines, cutting machines, automatic welding machines, metal cutting equipment, automatic assembly lines, automatic welding lines, mechanical transmission and handling equipment, and hazardous areas (toxic, high pressure, high temperature, etc.), where personal injuries are likely to be caused to operators, The safety grating sensor is a protective device to ensure the safe operation of workers.

Components of safety grating:

Emitter: composed of several light-emitting devices, emitting infrared light;

Light receiver: It is composed of several light receiving devices, which receive infrared light and correspond with the light emitting devices of the light emitter one by one to form a protective light curtain, generate light on and light off signals, and transmit the signals to the controller through the signal cable to control the external devices;

Signal cable: used to transmit signals between controller and illuminator and light receiver;
