7m retro-reflective sensor with universal AC/DC power, SPDT relay output, and IP64 protection. Reliable long-range detection for industrial automation.
The Omron E3JK-RR11-C 2M is a robust, industrial-grade retro-reflective photoelectric sensor equipped with a built-in AC/DC power supply. Operating with a visible red LED (624 nm) to simplify optical alignment, it delivers a versatile sensing distance ranging from 100 mm up to 7 meters (when used with the E39-R1 reflector). The sensor features an SPDT relay output for direct integration into diverse control circuits and is housed in a durable IP64-rated ABS casing. Packaged with a pre-wired 2-meter PVC cable, it operates reliably in harsh environmental conditions without the M.S.R. (Mutual Interference Reduction) function.

Deployed along expansive stretches of conveyor belts to detect the presence or absence of moving boxes and packaged goods.
Eliminates counting or timing errors caused by wide gaps or varying box sizes, reliably triggering diverters and wrapping machines using a single-sided wiring setup.
Installed across the thresholds of wide industrial warehouse doors to monitor the entry and exit of forklifts and personnel.
Prevents the accidental closure of heavy motorized doors on equipment or workers by instantaneously interrupting the safety circuit when the continuous red LED beam is broken.
Mounted on the gantry of heavy-duty overhead cranes to maintain strict safety boundaries between multiple cranes sharing the same rail.
Provides an immediate stop-signal override via its direct relay output if a neighboring crane approaches within a dangerous 7-meter proximity, preventing structural impacts.
