Omron E3Z-B67 Photoelectric Sensor
Omron E3Z-B67 is a retro-reflective photoelectric sensor without the MSR function, specified for clear plastic bottle sensing from 500 mm to 2 m. A 660 nm red LED establishes the optical path between the sensor and reflector, while the NPN output communicates the switching state to compatible machine-control circuitry. Light-ON or Dark-ON operation can be selected according to the required output logic. The sensor operates from 12 to 24 VDC and uses a standard 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-B67 provides the 2 m connector configuration. Related NPN retro-reflective sensors are available across Omron Industrial Sensors.

The Omron E3Z-B67 Photoelectric Sensor uses retro-reflective sensing without the MSR function for clear plastic bottle sensing from 500 mm to 2 m. A 660 nm red LED establishes the optical path between the sensor and reflector, while the NPN 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 machine logic. The sensor operates from 12 to 24 VDC and uses a standard 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.
For an Omron NPN retro-reflective sensor requiring an M8 connector and a sensing range extending to 2 m, the applicable model is the E3Z-B67. Ambient-light resistance reaches 3,000 lx under incandescent light and 10,000 lx under sunlight. Operating temperature extends from -25 to 55°C, with storage from -40 to 70°C without icing or condensation. Reverse supply polarity, output short-circuit, mutual-interference, and reversed-output polarity protection are specified. PBT and modified polyarylate are listed as body materials. Search terms such as Omron 2 m bottle sensor and Omron NPN M8 photoelectric sensor also correspond to this configuration. For a shorter-range connector model covering 80 to 500 mm, see the E3Z-B66.
