Omron E3S-AD88 Photoelectric Sensor
Omron E3S-AD88 is a PNP 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 electrical connection. Light-ON or Dark-ON operation can be selected according to the required machine logic, while a two-turn endless adjuster supports sensitivity setting. Response time is specified at 0.5 ms, and current consumption is 35 mA maximum. Within the E3S Series, the E3S-AD88 provides the PNP wide-view configuration. Related wide-view photoelectric sensors can be explored across Omron Industrial Sensing Products.

The Omron E3S-AD88 Photoelectric Sensor uses wide-view diffuse-reflective sensing with a built-in amplifier across a stated distance of 100 mm using a 100 × 100 mm white-paper reference target. Its 880 nm infrared LED supplies the optical source, while the PNP output transfers the 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, while a two-turn endless adjuster supports sensitivity setting. Operation or reset time is specified at 0.5 ms maximum, supporting quick switching during object presence and position sensing.
For an Omron PNP wide view photoelectric sensor requiring 100 mm sensing and an M12 connector, the relevant model is the E3S-AD88. Ambient-light resistance reaches 5,000 lx under incandescent light and 10,000 lx under sunlight. Operating temperature extends from -25 to 55°C, while storage ranges from -40 to 70°C without icing or condensation. Power-supply reverse polarity, output short-circuit, and mutual-interference prevention are listed. PBT, denatured polyallylate, and SUS304 are among the stated materials. Its specification also suits searches for an Omron 100 mm PNP sensor and Omron infrared wide view sensor. For the related NPN wide-view E3S configuration with the same stated 100 mm sensing distance, see E3S-AD68.
