Omron E3Z-D66 Photoelectric Sensor
Omron E3Z-D66 is a wide-view diffuse-reflective photoelectric sensor designed for direct object sensing across a range from 5 to 100 mm. Its 870 nm infrared LED directs light toward the target, while the returned optical signal provides the information used to establish the switching state. The NPN output transfers this state to compatible machine-control circuitry, and Light-ON or Dark-ON operation can be selected according to the required logic. The sensor operates from 12 to 24 VDC and uses an M8 connector for detachable electrical integration. A one-turn adjuster supports sensitivity setting, while response time is specified at 1 ms maximum. Within the E3Z Series, the E3Z-D66 provides an M8-connected option for wide-view diffuse sensors across Omron Industrial Products.

The Omron E3Z-D66 Photoelectric Sensor uses wide-view diffuse-reflective sensing across a 5 to 100 mm range. Its 870 nm infrared LED sends light toward the target, and the sensor evaluates the returned optical signal without requiring a separate reflector. The NPN output transfers the switching state to compatible industrial control equipment, while Light-ON or Dark-ON operation can be selected according to the required logic. The sensor operates from 12 to 24 VDC and uses an M8 connector for detachable wiring. Current consumption is specified at 30 mA maximum, response time at 1 ms maximum, and a one-turn adjuster supports sensitivity setting. Ambient-light resistance reaches 3,000 lx under incandescent light and 10,000 lx under sunlight.
For an Omron diffuse sensor requiring NPN output, an M8 connector, and a short wide-view sensing range, the relevant model is the E3Z-D66. Operating temperature extends from -25 to 55°C, while storage covers -40 to 70°C without icing or condensation. Insulation resistance is specified at 20 MΩ minimum at 500 VDC, and dielectric strength is 1,000 VAC for one minute. Reverse supply polarity, output short-circuit, mutual-interference, and reversed-output polarity protection are included. The PBT body supports compact machine mounting, while the detachable connector simplifies replacement or wiring changes. Its specification also suits searches for an Omron M8 diffuse sensor and Omron 100 mm infrared photoelectric sensor. For a longer-range M8-connected NPN diffuse model with a 1 m sensing distance, see the E3Z-D67.
