Product Overview
The Omron E3Z-T86 detects any opaque object that passes between a matched emitter and receiver pair, with a sensing range up to 15 m. manufactured by Omron Corporation. Hengyixin Automation ships this sensor from our Xiamen warehouse with a 30-day DOA return window and a datasheet PDF included in the box.
Through-beam is the most reliable of the three sensing modes: it ignores target color and reflectivity, works on shiny or dark surfaces, and isn't affected by ambient light. The PNP output suits North American / European wiring (sourcing into a PNP-compatible PLC input), and the M8 4-pin connector lets you swap a sensor without re-wiring — just unplug and replace.
At long range, align the receiver within a few degrees of the emitter axis; the green stability LED on the receiver confirms a clean signal.

FAQ for E3Z-T86
What's the difference between E3Z-T86 and E3Z-T81?
Same 15 m range, PNP output, and electrical specs. T81 (already done) has a pre-wired 2 m cable attached to the body — cheaper, but you have to re-wire to replace. T86 (this SKU) has an M8 connector — slightly more expensive, but you can swap a sensor by unplugging the M8 cable.
How do I choose Light-ON vs Dark-ON mode?
Use the white wire on the M8 connector: leave it open (or tie to 0 V) for Dark-ON (output ON when an object breaks the beam — the standard pick for object detection). Tie white to +V for Light-ON (output ON when the beam is clear — the right pick for safety-beam applications where you want a fault signal when the beam breaks).
Can the E3Z-T86 detect transparent objects?
No. Through-beam works by blocking light, so transparent or semi-transparent objects (clear glass, film, translucent bottles) may pass through without interrupting the beam. Use a polarized retro-reflective sensor (E3Z-R81 / R86) or a specialized transparent-detection sensor for clear objects.
What cable do I need?
One M8 4-pin female cable per sensor (emitter and receiver). The standard Omron pick is the XS3F-M421-402-A (2 m straight); 5 m and 10 m versions exist too. Third-party M8 4-pin cables from Phoenix Contact, Lumberg, or Binder work as well.
Is the E3Z-T86 suitable for outdoor use?
Yes, with care. IP67 handles rain and splashes, but mount the receiver out of direct sunlight (which can saturate the sensor), use weatherproof cable glands, and clean the lenses periodically. For harsher outdoor exposure, step up to the E3ZM series (stainless steel, IP69K).
