Omron E3JK-RR13 2M is a retro-reflective photoelectric sensor with an infrared LED, a sensing distance of up to 7 m with the E39-R1 reflector or 11 m with the E39-R2, SPDT relay output and a wide 24–240 VAC/DC power supply. It runs directly on AC or DC without a separate power supply, and its invisible infrared beam suits applications where a visible light spot is not wanted. For the same range with a visible red LED, see the E3JK-RR11 2M. It is part of the Omron E3JK Series. Explore more Omron photoelectric sensors.
