Omron E3Z-T61 5M Photoelectric Sensor
The Omron E3Z-T61 5M Photoelectric Sensor uses separate emitter and receiver units to establish a through-beam sensing path across distances up to 15 m. The E3Z-T61-L 5M emitter uses an 870 nm infrared LED to transmit the sensing beam toward the E3Z-T61-D 5M receiver, allowing an object to be detected when it interrupts the optical path. Its NPN output provides the resulting detection state to compatible machine-control equipment, while Light-ON or Dark-ON operation can be selected according to the required control logic. The sensor operates from 12 to 24 VDC, and 5 m pre-wired cables support installation over the required machine area. Built for long-range through-beam detection, the E3Z-T61 sits within the E3Z Series and the wider 15 m through-beam sensor range developed by Omron detection products.

The Omron E3Z-T61 5M Photoelectric Sensor uses through-beam sensing across a specified distance of 15 m. The optical arrangement includes the E3Z-T61-L emitter and E3Z-T61-D receiver, with an 870 nm infrared LED establishing the sensing beam. An opaque target of 12 mm diameter minimum is specified. The NPN output supports compatible industrial control circuitry, with load supply voltage up to 26.4 VDC and load current up to 100 mA. The sensing 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 electrical connection.
For an Omron NPN through-beam sensor requiring a 15 m sensing distance and longer fixed wiring, the relevant model is the E3Z-T61. Operating temperature extends from -25 to 55°C, with storage from -40 to 70°C under the supplied conditions. Operation and stability indicators provide visual status, while the emitter has a dedicated power indicator. 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-T61 arrangement with shorter 2 m pre-wired cables, see E3Z-T61 2M.
