Omron E3JK-RR11 2M Retro-Reflective Photoelectric Sensor 24-240 VAC/DC Relay Output 2 m Cable

The Omron E3JK-RR11 2M is a high-performance retro-reflective photoelectric sensor designed for reliable object detection in industrial automation, conveyor systems, and machine control applications. This sensor uses a red LED light source and a reflector (sold separately) to detect objects at long range — up to approximately 7 m with a standard reflector and up to 11 m with a larger reflector depending on setup.

Featuring a robust ABS housing and pre-wired 2 m cable, the E3JK-RR11 2M supports AC/DC supply voltages from 24 V to 240 V, making it suitable for diverse industrial installations. The relay (SPDT) output with L-ON/D-ON selectable operation allows for flexible integration into control logic systems. Its manual sensitivity adjustment, 20 ms response time, and IP64 protection rating provide dependable performance in dusty or splash-prone environments.
