Omron E3ZM-T86 Photoelectric Sensor
Omron E3ZM-T86 is a connector-type through-beam photoelectric sensor designed for object sensing across a specified distance of 15 m. The sensing system uses the E3ZM-T86-L emitter and E3ZM-T86-D receiver, with a 660 nm red LED establishing the optical path between them. The PNP output communicates the switching state to compatible machine-control circuitry, while a Light-ON or Dark-ON switch allows the required output logic to be selected. The sensor operates from 10 to 30 VDC and uses an M8 4-pin connector for electrical integration. Each sensing unit consumes up to 20 mA, while response time is 1 ms maximum. The E3ZM-T86 provides removable wiring within the 15 m red LED through-beam sensor range across Omron Automation Products.

The Omron E3ZM-T86 Photoelectric Sensor uses separate E3ZM-T86-L emitter and E3ZM-T86-D receiver units to establish a 15 m through-beam sensing path. A 660 nm red LED forms the optical beam, and an opaque target of 12 mm diameter minimum is specified. The PNP output supports a load supply voltage up to 30 VDC and load current up to 100 mA, with residual voltage limited to 2 V maximum. The sensing units operate from 10 to 30 VDC and consume up to 20 mA each. A Light-ON or Dark-ON switch selects the output behavior, while operate or reset time is 1 ms maximum. A one-turn adjuster supports setup, and an M8 4-pin connector provides detachable electrical integration. Operation and stability indicators provide visual status information.
For an Omron PNP through-beam sensor requiring 15 m sensing with connector-based wiring, the relevant model is the E3ZM-T86. Operating temperature is specified from -25 to 55°C, with storage extending from -40 to 70°C. Electrical protection includes reversed supply polarity, output short circuit, and reversed output polarity. SUS316, methacrylic resin, PES, PEEK, and fluoro rubber are listed among the materials. The M8 interface differentiates this model from pre-wired T81 configurations while retaining a long optical path. For a related 15 m PNP through-beam model with 2 m fixed cables, see E3ZM-T81 2M.
