Omron E3JK-RR12-C 2M is a retro-reflective photoelectric sensor with MSR (mirror surface rejection), supplied with a reflector and mounting bracket. It senses up to 6 m with the E39-R1 reflector or 10 m with the E39-R2, has SPDT relay output and runs on a wide 24–240 VAC/DC supply. The MSR function prevents shiny objects from being mistaken for the reflector, and with the accessories included, it is ready to install. For the sensor alone, see the E3JK-RR12 2M. It is part of the Omron E3JK Series. Explore more Omron photoelectric sensors.
