Light Curtains (217 suppliers)

Light curtains are photoelectric transmitters that project infrared beams to a receiver. They are used to guard openings and work spaces in or around machinery. When an opaque object interrupts the infrared beam, a stop signal is sent to the hazardous process to protect personnel or equipment.
