The FSA safety light curtain products utilize photo-synchronization technology: featuring a unique photo-synchronization technology, they replace traditional data cable synchronization, eliminate signal interference, and simultaneously eliminate the need for longer data cable connections.

Safety Light Curtain, an infrared safety protection device, consists of an emitter and a receiver installed on opposite sides. It is controlled digitally by a microcontroller and a microprocessor, creating an infrared light curtain barrier that scans at high speed. When people or objects enter the barrier area, the control system quickly shifts the output signal level, causing the load to activate and stopping the machine. Once people or objects move out of the warning area, the load closes automatically, ensuring safety protection.
