Omron E3JK-TR12 2M Photoelectric Sensor

Omron E3JK-TR12 2M is a through-beam photoelectric sensor with a 5 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-TR12-L 2M) and receiver (E3JK-TR12-D 2M), and runs directly on AC or DC without a separate power supply. A version with mounting brackets is available as the E3JK-TR12-C 2M. It is part of the Omron E3JK Series. Explore more Omron photoelectric sensors.
