Omron E3S-AD11 2M Photoelectric Sensor
Omron E3S-AD11 2M is an NPN 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, while returned light provides the sensing information without requiring a separate reflector. The sensor operates from 10 to 30 VDC and includes a 2 m pre-wired cable for 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 load current up to 100 mA. Within the E3S Series, the E3S-AD11 2M provides the pre-wired NPN option. Related short-range diffuse sensors are available across Omron Sensing Products.

The Omron E3S-AD11 2M 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. A 660 nm red LED provides the optical source, while the NPN output transfers the switching state to compatible machine-control circuitry. The sensor operates from 10 to 30 VDC and includes a 2 m pre-wired cable. Current consumption is specified at 30 mA maximum, with approximately 15 mA additional current when the turbo function is used. 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 setup. Operation or reset time is specified at 0.5 ms maximum.
For an Omron NPN diffuse reflective photoelectric sensor requiring 10 to 200 mm sensing and fixed cable wiring, the relevant model is the E3S-AD11. 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 matches searches for an Omron 200 mm NPN sensor and Omron built-in amplifier diffuse sensor. For a related E3S PNP diffuse-reflective model with the same 10 to 200 mm sensing range and an M12 connector, see E3S-AD36.
