Technical Overview
The Omron E3JK-RR11-C is a pre-wired E3JK retro-reflective, without msr photoelectric sensor, rated for 7 m with E39-R1 reflector or 11 m with E39-R2 reflector. This configuration uses red led, 624 nm, 24–240 vdc ±10% or 24–240 vac ±10%, 50/60 hz and relay spdt output; the stated response time is 20 ms max. and enclosure rating is IP64. The -C version includes a mounting bracket, and retro-reflective -C versions include an E39-R1 reflector. Current supply status is not established by the consulted manufacturer material and is recorded as Unknown.

Suggested applications
Engineering suggestions require suitability checks for your installation.
1. Conveyor object detection
A conveyor line may need to identify products across a defined sensing gap or against a fixed surface.
Potential use
Evaluate the retro-reflective, without msr geometry and 7 m with E39-R1 reflector or 11 m with E39-R2 reflector range with the actual target; confirm output wiring and response in the control circuit.
Retro-reflective without MSR
7 m with E39-R1 reflector or 11 m with E39-R2 reflector
Relay SPDT
20 ms max.
2. Machine station presence confirmation
A station may need a discrete presence signal for a part or carrier before the next operation.
Potential use
Use the relay spdt output with a compatible input and verify the target, reflector or emitter/receiver alignment as applicable.
