Safety light curtain, a device based on photoelectric sensing technology, consists of a transmitter and a receiver. The emitter emits parallel infrared beams forming a light curtain, and the receiver detects these beams. Under normal circumstances, the receiver can detect the beam from the transmitter. If an object blocks the beam, the receiver will send a signal to the control system, and the control system will perform a preset response such as stopping the machine to ensure safety. This light curtain can effectively prevent possible safety accidents.
