Omron E3Z-LT86 Photoelectric Sensor
Omron E3Z-LT86 is a laser through-beam photoelectric sensor designed for object sensing across a specified distance of up to 60 m. Its sensing arrangement uses the E3Z-LT86-L emitter and E3Z-LT86-D receiver, with a 655 nm red laser diode establishing the optical beam between them. The PNP output communicates the switching state to compatible machine-control circuitry, while Light-ON and Dark-ON operation supports different control requirements. The sensor operates from 12 to 24 VDC and uses an M8 4-pin connector arrangement for electrical integration. Total current consumption is specified at 35 mA, while response time is 1 ms maximum. Within the E3Z Series, the E3Z-LT86 provides connector wiring within the PNP 60 m through-beam sensor range across Omron Sensing Range.

The Omron E3Z-LT86 Photoelectric Sensor uses laser through-beam sensing across a specified distance of up to 60 m. Its optical arrangement consists of the E3Z-LT86-L emitter and E3Z-LT86-D receiver, with a 655 nm red laser diode establishing the beam between the two units. An opaque target of 12 mm diameter minimum is specified. The PNP output supports compatible industrial control inputs, while load supply voltage is stated up to 26.4 VDC and load current up to 100 mA. The units operate from 12 to 24 VDC and consume 35 mA in total, specified as 15 mA for the emitter and 20 mA for the receiver. Light-ON or Dark-ON operation is available, and response time is 1 ms maximum. An M8 4-pin connector arrangement provides the electrical interface.
For an Omron PNP laser through-beam sensor requiring connector wiring and a 60 m sensing distance, the relevant model is the E3Z-LT86. A one-turn adjuster supports setup, while operation and stability indicators provide visual status information and the emitter includes a power indicator. Operating temperature extends from -10 to 55°C, with storage from -25 to 70°C. Reversed power-supply polarity protection, output short-circuit protection, and reversed output polarity protection are included. Ambient-light resistance reaches 3,000 lx for incandescent illumination and 10,000 lx for sunlight. For a related pre-wired PNP model using 2 m cables and the same stated sensing distance, see E3Z-LT81 2M.
