E3Z-T61 OMRON Photoelectric Switch Sensor E3ZT61 Brand New Sealed
OMRON E3Z-T61 15 m NPN Through-Beam Photoelectric Sensor
Detection Across the Conveyor
The OMRON E3Z-T61 uses a separate emitter and receiver to detect objects interrupting an infrared beam. Its 15 m sensing distance allows installation across wide equipment openings. The built-in amplifier provides a switching signal directly to a compatible control input.

Production-Line Applications
Typical applications include carton detection in packaging machinery, part counting on conveyors, and presence checks in automated assembly. Through-beam sensing suits opaque products that reliably block the optical path.
Alignment and Adjustment
Mount the emitter and receiver facing each other. Align the beam, then set sensitivity using the one-turn adjuster. Check the receiver’s stability indicator and confirm switching with the actual target. Select Light-ON or Dark-ON to match the control sequence.
FAQ
Q1: Does the E3Z-T61 need a reflector?
A: No. It uses a separate emitter and receiver.
