Omron E3S-AD68 Photoelectric Sensor
Omron E3S-AD68 is an NPN diffuse-reflective photoelectric sensor designed for wide-view sensing across a distance of 100 mm. Its 880 nm infrared LED directs light toward the target area, while returned light supplies the sensing information to the built-in amplifier. The sensor operates from 10 to 30 VDC and uses an M12 connector for detachable machine wiring. Light-ON or Dark-ON operation can be selected, and a two-turn endless adjuster supports sensitivity setting. Response time is specified at 0.5 ms, while current consumption is 35 mA maximum. Within the E3S Series, the E3S-AD68 provides the NPN wide-view configuration. Related wide-view diffuse sensors are available across the Omron Sensor Range.

The Omron E3S-AD68 Photoelectric Sensor uses a wide-view diffuse-reflective sensing arrangement with a built-in amplifier across a stated distance of 100 mm. Its 880 nm infrared LED directs light toward the target area, while the NPN output transfers the resulting switching state to compatible machine-control circuitry. The sensor operates from 10 to 30 VDC and uses an M12 connector for detachable electrical connection. Current consumption is specified at 35 mA maximum, while load current is rated up to 100 mA. Light-ON or Dark-ON operation can be selected according to the required control logic. A two-turn endless adjuster with an indicator supports sensitivity setup. Operation or reset time is specified at 0.5 ms maximum, supporting quick output changes during machine operation.
For an Omron NPN wide view photoelectric sensor requiring 100 mm sensing and an M12 connector, the relevant model is the E3S-AD68. The stated reference target is white paper measuring 100 × 100 mm. Ambient-light resistance reaches 5,000 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. Power-supply reverse polarity, output short-circuit, and mutual-interference prevention are listed. Its specification also matches searches for an Omron 100 mm infrared sensor and Omron NPN M12 sensor. For a related PNP E3S wide-view model using the same 100 mm stated sensing distance, see E3S-AD88.
