Omron E3JK-TR11 2M is a through-beam photoelectric sensor with a long 40 m sensing distance, SPDT relay output and a wide 24–240 VAC/DC power supply. It comes as a set of a separate emitter (E3JK-TR11-L 2M) and receiver (E3JK-TR11-D 2M), runs directly on AC or DC without a separate power supply, and its visible red LED makes alignment easy over long distances. A version with a mounting bracket is available as the E3JK-TR11-C 2M. It is part of the Omron E3JK Series. Explore more Omron photoelectric sensors.
