Omron E3Z-T61A 2M Photoelectric Sensor
The Omron E3Z-T61A 2M Photoelectric Sensor uses a through-beam sensing arrangement to detect objects that interrupt the optical path between its separate emitter and receiver. With a sensing distance of up to 10 m, the sensor can monitor wider conveyor paths, machine openings, and material movement areas. A 660 nm red LED establishes the sensing beam, while the NPN output communicates object detection to compatible PLC inputs and machine-control circuits. Selectable Light-ON or Dark-ON operation allows the output behavior to match the required control sequence. The unit operates from 12 to 24 VDC and includes a 2 m pre-wired cable for installation. For through-beam detection, the E3Z Series includes the E3Z-T61A within the through-beam sensing range available from Omron industrial sensing.

The Omron E3Z-T61A 2M Photoelectric Sensor uses through-beam sensing across a specified distance of 10 m. The sensing arrangement includes the E3Z-T61-A-L emitter and E3Z-T61-A-D receiver, with a 660 nm red LED establishing the optical path between them. The NPN output communicates the switching state to compatible industrial control circuitry. The sensor operates from 12 to 24 VDC and consumes 35 mA maximum in total, with 15 mA maximum specified for the emitter and 20 mA maximum for the receiver. Light-ON or Dark-ON operation can be selected according to the required control sequence, while operate or reset time is 1 ms maximum. A one-turn adjuster supports setup, and 2 m pre-wired cables provide fixed electrical connection. Ambient-light limits are specified for incandescent illumination and sunlight.
For an Omron red LED through-beam sensor requiring NPN output and 10 m sensing, the relevant model is the E3Z-T61A. Operating temperature is stated from -25 to 55°C under the supplied conditions, while storage extends from -40 to 70°C. Operating humidity covers 35% to 85%, and insulation resistance is specified at 20 MΩ minimum at 500 VDC. Reversed power-supply polarity, output short-circuit, and reversed output-polarity protection are listed. PBT is specified as the housing material. For the same sensing arrangement with longer 5 m pre-wired cables, see E3Z-T61A 5M.
