Omron E3JK-DN13 2M is an NPN diffuse-reflective photoelectric sensor with a long 2.5 m sensing distance, an infrared LED and a pre-wired 2 m cable. It detects targets directly from reflected light without a reflector, 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-DN11 2M. It is part of the Omron E3JK Series. Explore more Omron photoelectric sensors.
