Omron E3Z-T61K 2M Photoelectric Sensor
The Omron E3Z-T61K 2M Photoelectric Sensor provides through-beam object detection across a sensing distance of up to 15 m. The sensing system combines the E3Z-T61K-L 2M emitter with the E3Z-T61K-D 2M receiver, using an infrared LED operating at 870 nm to establish the optical path between the two units. A target is detected when it interrupts the infrared light reaching the receiver. The NPN output transfers the resulting detection state to compatible industrial control circuitry, while selectable Light-ON or Dark-ON operation allows the switching behavior to match the required control logic. The sensor operates from 12 to 24 VDC and uses 2 m pre-wired cables for connection. For 15 m NPN through-beam sensing, the E3Z Series includes the E3Z-T61K within the industrial through-beam sensor range developed by Omron industrial sensing.

The Omron E3Z-T61K 2M Photoelectric Sensor uses through-beam sensing across a specified distance of 15 m. The sensing arrangement includes the E3Z-T61K-L emitter and E3Z-T61K-D receiver, with an 870 nm infrared LED establishing the optical path. An opaque target of 12 mm diameter minimum is specified. The NPN output supports load supply voltage up to 26.4 VDC and load current up to 100 mA. The units operate from 12 to 24 VDC and consume 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 is selectable, 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.
For an Omron infrared through-beam sensor requiring NPN output and 15 m sensing, the relevant model is the E3Z-T61K. Operating temperature is specified 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 includes a power indicator. Reversed power-supply polarity protection, output short-circuit protection, and reversed output-polarity protection are listed. PBT and modified polyarylate are specified among the materials. For a related E3Z-T61K listing with a longer 5 m pre-wired connection, see E3Z-T61K 5M.
