Omron E3S-AD36 Photoelectric Sensor
Omron E3S-AD36 is a PNP diffuse-reflective photoelectric sensor with a built-in amplifier for direct object sensing from 10 to 200 mm. Its 660 nm red LED sends light toward the target, and returned light provides the sensing information required for switching. 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 setup. Response time is specified at 0.5 ms, and load current is rated up to 100 mA. Within the E3S Series, the E3S-AD36 provides the PNP connector option. Related 200 mm diffuse photoelectric sensors can be explored across Omron Industrial Sensor Products.

The Omron E3S-AD36 Photoelectric Sensor uses diffuse-reflective sensing with a built-in amplifier for direct object sensing from 10 to 200 mm using a 100 × 100 mm white-paper reference target. Its 660 nm red LED directs light toward the target, while the PNP output transfers the resulting switching state to compatible PLC inputs and 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 30 mA maximum, with approximately 15 mA additional current when the turbo function is active. 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.
For an Omron PNP diffuse reflective photoelectric sensor requiring 10 to 200 mm sensing and M12 connection, the corresponding model is the E3S-AD36. Operating temperature extends from -25 to 55°C, while storage ranges from -40 to 70°C without icing or condensation. Ambient-light resistance reaches 5,000 lx under incandescent light and 10,000 lx under sunlight. Power-supply reverse polarity, output short-circuit, and mutual-interference prevention are included. Its specification also suits searches for an Omron 200 mm PNP sensor and Omron M12 diffuse sensor. PBT, denatured polyallylate, and SUS304 are among the listed materials.
