Omron E3JK-R4M1 is a retro-reflective photoelectric sensor with a 4 m sensing distance, relay output and a wide 12–240 VDC / 24–240 VAC power supply. It works with a reflector, detects any object that breaks the beam, and its visible red LED makes reflector alignment easy. This model operates in Light-ON mode; for Dark-ON, see the E3JK-R4M2. For a shorter 2.5 m range, see the E3JK-R2M1. It is part of the Omron E3JK Series. Explore more Omron photoelectric sensors.
