Omron E3Z-B66 Photoelectric Sensor
Omron E3Z-B66 is a retro-reflective photoelectric sensor without the MSR function for sensing clear plastic bottles from 80 to 500 mm. Its 660 nm red LED establishes the optical path, while the NPN output transfers the switching state to compatible industrial control equipment. Light-ON or Dark-ON operation can be selected to match the required control logic, and a one-turn adjuster supports sensitivity setting. The sensor operates from 12 to 24 VDC, consumes up to 30 mA, and responds within 1 ms. A standard M8 connector provides the electrical interface. Within the E3Z Series, the E3Z-B66 provides the short-range connector configuration. Related clear bottle photoelectric sensors can be reviewed across Omron Sensor Products.

The Omron E3Z-B66 Photoelectric Sensor uses retro-reflective sensing without the MSR function for clear plastic bottle sensing across an 80 to 500 mm distance. Its 660 nm red LED establishes the optical path, while the NPN output supports a load supply voltage of up to 26.4 VDC and load current of up to 100 mA. Light-ON or Dark-ON operation can be selected according to the required control logic. The sensor operates from 12 to 24 VDC, consumes up to 30 mA, and responds within 1 ms. A standard M8 connector provides the electrical interface, while the one-turn adjuster supports sensitivity setting. Orange operation and green stability indicators provide visual status information.
For an Omron clear bottle sensor requiring NPN output, an M8 connector, and an 80 to 500 mm sensing range, the relevant model is the E3Z-B66. Ambient-light resistance is specified at 3,000 lx under incandescent light and 10,000 lx under sunlight. Operating temperature extends from -25 to 55°C, while storage covers -40 to 70°C without icing or condensation. Reverse supply polarity, output short-circuit, mutual-interference, and reversed-output polarity protection are listed. PBT and modified polyarylate are specified as construction materials. Its specification also suits searches for an Omron M8 photoelectric sensor and Omron NPN bottle sensor. For a longer-range NPN connector version covering 500 mm to 2 m, see the E3Z-B67.
