FGM-LG series safety light curtain is compact, high precision, and has strong signal transmitting and receiving ability.

The control principle is that the light emitter emits light signal directly accepted by the light receiver to form a protective light curtain, the light receiver monitors the light curtain's on/off status and processes the light curtain's on/off signal through the internal circuit.

Directly output low level (when the light is on) or high level (when the light is on), through the transmission line to the PLC or alarm alarm circuit, to achieve the equipment to stop or send out the safety alarm.
