Omron E3Z-T61A 5M Photoelectric Sensor
The Omron E3Z-T61A 5M Photoelectric Sensor uses separate emitter and receiver units to provide through-beam object detection across a distance of up to 10 m. The E3Z-T61A-L 5M emitter sends red LED light at 660 nm toward the E3Z-T61A-D 5M receiver, establishing an optical path that is interrupted when a target enters the sensing area. An NPN output communicates the resulting detection state to compatible machine-control circuitry, while selectable Light-ON or Dark-ON operation supports different switching requirements. The sensor operates from 12 to 24 VDC and includes 5 m pre-wired cables for electrical connection. For 10 m NPN through-beam detection, the E3Z Series includes the E3Z-T61A within the long-range through-beam sensor range associated with Omron industrial automation.

The Omron E3Z-T61A 5M Photoelectric Sensor uses through-beam sensing across a specified distance of 10 m. The optical arrangement includes the E3Z-T61A-L emitter and E3Z-T61A-D receiver, with a 660 nm red LED establishing the sensing beam. An opaque target of 12 mm diameter minimum is specified. The NPN output supports a load supply voltage up to 26.4 VDC and a load current up to 100 mA. The units operate from 12 to 24 VDC and consume 35 mA maximum in total, specified as 15 mA for the emitter and 20 mA for the receiver. Light-ON or Dark-ON operation is selectable, while operate or reset time is 1 ms maximum. A one-turn adjuster supports setup, and 5 m pre-wired cables provide extended fixed wiring.
For an Omron NPN through-beam photoelectric sensor requiring visible red light, 10 m sensing, and longer cables, the relevant model is the E3Z-T61A. Operation and stability indicators provide visual status, while the emitter has a dedicated power indicator. Operating temperature extends from -25 to 55°C, with storage from -40 to 70°C. Reversed power-supply polarity, output short-circuit, and reversed output-polarity protection are specified. PBT and modified polyarylate are listed among the materials. For the same E3Z-T61A arrangement with shorter 2 m pre-wired cables, see E3Z-T61A 2M.
