Omron E3FA-RN12 2M Photoelectric Sensor

Omron E3FA-RN12 2M is an NPN coaxial retro-reflective photoelectric sensor with a 0–500 mm sensing distance and a pre-wired 2 m cable. Its coaxial optics detect targets right up to the sensor face, and the MSR (mirror surface rejection) function prevents shiny objects from being mistaken for the E39-R1S reflector. For longer reflector spacing up to 4 m, see the E3FA-RN11 2M. It is part of the Omron E3FA Series. Explore more Omron photoelectric sensors.
