Omron E3JK-TR12-C 2M through-beam sensor: 5 m; Relay SPDT at receiver; IP64, 2 m cable.
The Omron E3JK-TR12-C is a pre-wired E3JK through-beam emitter and receiver set photoelectric sensor, rated for 5 m. This configuration uses red led, 624 nm, 24–240 vdc ±10% or 24–240 vac ±10%, 50/60 hz and relay spdt at receiver 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.

Engineering suggestions require suitability checks for your installation.
A conveyor line may need to identify products across a defined sensing gap or against a fixed surface.
Evaluate the through-beam emitter and receiver set geometry and 5 m range with the actual target; confirm output wiring and response in the control circuit.
A station may need a discrete presence signal for a part or carrier before the next operation.
Use the relay spdt at receiver output with a compatible input and verify the target, reflector or emitter/receiver alignment as applicable.
