Omron E3JK-RR11 2M Photoelectric Sensor

Omron E3JK-RR11 2M is a retro-reflective photoelectric sensor with a sensing distance of up to 7 m with the E39-R1 reflector, or 11 m with the E39-R2, SPDT relay output and a wide 24–240 VAC/DC power supply. It runs directly on AC or DC without a separate power supply, and its visible red LED makes reflector alignment easy. A version with a mounting bracket is available as the E3JK-RR11-C 2M. It is part of the Omron E3JK Series. Explore more Omron photoelectric sensors.
