Omron E3JK-TR13 2M is a through-beam photoelectric sensor with a long 40 m sensing distance, an infrared LED, SPDT relay output and a wide 24–240 VAC/DC power supply. It comes as a set of a separate emitter (E3JK-TR13-L 2M) and receiver (E3JK-TR13-D 2M), runs directly on AC or DC without a separate power supply, and its invisible infrared beam suits applications where a visible light spot is not wanted. For the same range with a visible red LED, see the E3JK-TR11 2M. It is part of the Omron E3JK Series. Explore more Omron photoelectric sensors.
