Omron E3FA-RP11 2M is a PNP retro-reflective photoelectric sensor with a 0.1–4 m sensing distance and a pre-wired 2 m cable. It works with the E39-R1S reflector, and its MSR (mirror surface rejection) function prevents shiny objects from being mistaken for the reflector. For the same sensor with NPN output, see the E3FA-RN11 2M. It is part of the Omron E3FA Series. Explore more Omron photoelectric sensors.
