E3SCR11

Overview of Omron E3SCR11

The Omron E3SCR11 is a rugged, metal body, polarized retroreflective photoelectric sensor designed for long sensing distances. It offers selectable NPN/PNP output (open collector) and Light-ON/Dark-ON operation modes with fuzzy logic-enhanced mutual interference protection. Its sensing distance is 3 meters when used with the E39-R1 reflector.
