Omron E3JK-RP12 2M Photoelectric Sensor

Omron E3JK-RP12 2M is a PNP retro-reflective photoelectric sensor with MSR (mirror surface rejection), a sensing distance of up to 6 m with the E39-R1 reflector or 10 m with the E39-R2, and a pre-wired 2 m cable. The MSR function prevents shiny or glossy objects from being mistaken for the reflector, so they are detected reliably. For the same sensor with NPN output, see the E3JK-RN12 2M. It is part of the Omron E3JK Series. Explore more Omron photoelectric sensors.
