Omron E3S-AD87 Photoelectric Sensor
Omron E3S-AD87 is a PNP diffuse-reflective photoelectric sensor with a vertical housing for direct object sensing across a distance of up to 700 mm. Its 880 nm infrared LED sends light toward the target, 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, 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-AD87 provides the longer-range PNP diffuse option. Related 700 mm diffuse sensors are available across Omron Sensing Range.

The Omron E3S-AD87 Photoelectric Sensor uses diffuse-reflective sensing with a built-in amplifier for direct object sensing across a maximum distance of 700 mm using a 200 × 200 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 equipment. 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 logic. A two-turn endless adjuster supports sensitivity setting, while operation or reset time is specified at 0.5 ms maximum.
For an Omron PNP diffuse reflective photoelectric sensor requiring a longer 700 mm sensing range and M12 wiring, the corresponding model is the E3S-AD87. 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 is specified from -40 to 70°C without icing or condensation. Power-supply reverse polarity, output short-circuit, and mutual-interference prevention are listed. Its specification also matches searches for an Omron 700 mm PNP sensor and Omron long range diffuse sensor. For a related E3S PNP diffuse-reflective model with a shorter 10 to 200 mm sensing range, see E3S-AD86.
