Omron E3Z-LR86 Photoelectric Sensor
Omron E3Z-LR86 is a laser retro-reflective photoelectric sensor with an MSR function for sensing opaque targets from 0.2 to 7 m when used with the E39-R12 reflector. Its 655 nm red laser establishes the optical path toward the reflector, while the PNP open-collector output communicates the switching state to compatible machine-control circuitry. Light-ON or Dark-ON operation can be selected according to the required logic. The sensor operates from 12 to 24 VDC and uses a 4-pin M8 connector for electrical integration. Current consumption is specified at 30 mA maximum, response time at 1 ms maximum, and a one-turn adjuster supports sensitivity setting. Within the E3Z Series, the E3Z-LR86 provides connector-based PNP sensing within the laser MSR sensor range across Omron Industrial Sensor Products.

The Omron E3Z-LR86 Photoelectric Sensor uses laser retro-reflective sensing with an MSR function across a range from 0.2 to 7 m when used with the E39-R12 reflector. Its 655 nm red laser establishes the optical path, while the PNP open-collector output supports up to 100 mA load current and a maximum load supply voltage of 26.4 VDC. Light-ON or Dark-ON operation can be selected according to the required control logic. The sensor operates from 12 to 24 VDC and uses a 4-pin M8 connector for electrical integration. Current consumption is specified at 30 mA maximum, response time at 1 ms maximum, and a one-turn adjuster supports sensitivity setting. Orange operation and green stability indicators provide visual operating information.
For an Omron long-range laser sensor requiring PNP output and detachable M8 wiring, the applicable model is the E3Z-LR86. Ambient-light resistance reaches 3,000 lx under incandescent light and 10,000 lx under sunlight. Operating temperature extends from -10 to 55°C, while storage covers -25 to 70°C without icing or condensation. Reverse supply polarity, output short-circuit, mutual-interference, and reversed-output polarity protection are included. PBT and methacrylic resin are listed as body materials. The 0.2 to 7 m range supports longer optical paths where connector-based wiring is preferred. Its specification also matches searches for an Omron PNP M8 laser sensor and Omron MSR retro-reflective sensor. For the NPN M8 version with the same sensing range, see the E3Z-LR66.
