A safety grating is a safety protection device used to detect and prevent objects or personnel from entering hazardous areas. It is composed of a photoelectric transmitter and receiver, which monitors whether there are objects or people entering the hazardous area by emitting a beam of light and detecting the received reflected light.

When an object or person enters a hazardous area, the safety grating will immediately emit a signal, usually processed by a safety controller and corresponding safety measures implemented, such as stopping the operation of the machine or equipment. This type of safety protection device is widely used in industrial production lines, robots, automated warehouses, and other situations where personnel safety needs to be protected.

In short, the safety grating is an important safety protection device that can protect the safety of personnel, protect the safe operation of equipment, and improve production efficiency.
