A safety grating is a safety protection device used to monitor and protect the safety of personnel or objects in a specific area. The safety grating is detected by an infrared beam. When an object enters the safety area, the grating will detect it and output a signal to the controller, thereby triggering the safety protection mechanism.

The working principle of a safety grating is to use a transmitter to emit an infrared beam, and a receiver to receive the beam. When the beam of light is blocked by an obstacle, the grating outputs a signal to notify the controller, triggering an alarm or safety protection measures. A security grating typically consists of a set of transmitters and receivers, which can be connected to multiple gratings as needed to achieve a larger security area.

Safety gratings are widely used in robots, automated production lines, conveyor belts, metallurgy, food processing, elevators, and other fields. In the robot system, the safety grating is used to detect the movement range of the robot to prevent collisions between the robot and personnel. In automated production lines, safety gratings are used to monitor and protect the safety of workers in specific areas. In conveyor belts and elevator systems, safety gratings are used to monitor objects entering or leaving specific areas to protect the safety of personnel and equipment. In the metallurgical and food processing industries, safety gratings are used to monitor and protect workers' safety during production processes.

In short, as an important safety protection device, safety gratings have been widely used in various automation fields, effectively protecting the safety of personnel and equipment, and improving production efficiency and quality.
