Omron E3ZM-T61 2M Photoelectric Sensor
Omron E3ZM-T61 2M is a through-beam photoelectric sensor designed for object sensing across a specified distance of 15 m. The sensing arrangement uses the E3ZM-T61-L emitter and E3ZM-T61-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, while a Light-ON or Dark-ON switch supports different machine sequences. The sensor operates from 10 to 30 VDC and uses 2 m pre-wired cables for electrical connection. The emitter and receiver each consume up to 20 mA, while response time is 1 ms maximum. Within the E3ZM Series, the E3ZM-T61 2M provides fixed wiring within the 15 m through-beam sensor range across Omron Automation Sensors.

The Omron E3ZM-T61 2M Photoelectric Sensor uses through-beam sensing across a specified distance of 15 m. The optical arrangement consists of the E3ZM-T61-L emitter and E3ZM-T61-D receiver, with a 660 nm red LED establishing the beam between them. An opaque target of 12 mm diameter minimum is specified. The NPN output supports compatible industrial control circuitry, with load supply voltage up to 30 VDC and load current up to 100 mA. Both sensing units operate from 10 to 30 VDC and consume up to 20 mA each. A Light-ON or Dark-ON switch controls the output behavior, 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. Receiver indicators show operation and stability, while the emitter has a power indicator.
For an Omron NPN through-beam sensor requiring 15 m sensing and pre-wired installation, the relevant model is the E3ZM-T61. Operating temperature is specified from -25 to 55°C, with storage from -40 to 70°C. Reversed supply polarity protection, output short-circuit protection, and reversed output-polarity protection are included. SUS316, methacrylic resin, PES, PEEK, and fluoro rubber are listed among the materials. The visible red LED differentiates this supplied 2 m configuration from the 5 m listing, which states an infrared light source. For the same model designation with longer cable routing, see E3ZM-T61 5M.
