Home Products Photoelectric Sensors Omron E3JK Series E3JK-RN12 2M Omron E3JK-RN12 2M Photoelectric Sensor Omron E3JK-RN12 2M is an NPN 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 a standard model with longer range, see the E3JK-RN11 2M. It is part of the Omron E3JK Series . Explore more Omron photoelectric sensors .
