Omron E3S-AT36 Photoelectric Sensor
Omron E3S-AT36 is a PNP through-beam photoelectric sensor with a horizontal design and built-in amplifier for object sensing across a distance of up to 7 m. Its 660 nm red LED establishes the optical path between separate emitter and receiver units, while the PNP output transfers the 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 wiring. Light-ON or Dark-ON operation can be selected, while a two-turn endless adjuster supports sensitivity setting. Both emitter and receiver consume up to 20 mA, and response time is specified at 0.5 ms. Within the E3S Series, the E3S-AT36 provides the PNP connector option.

The Omron E3S-AT36 Photoelectric Sensor uses through-beam sensing with a horizontal design and built-in amplifier across a maximum distance of 7 m. A 660 nm red LED forms the optical path between separate emitter and receiver units, while the PNP output changes state when an object interrupts the beam. The sensor operates from 10 to 30 VDC and uses an M12 connector for detachable electrical connection. Both emitter and receiver consume up to 20 mA, with approximately 15 mA additional consumption when the turbo function is active. Load current is specified at 100 mA maximum and load supply voltage at 30 VDC maximum. 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 maximum.
For an Omron PNP through beam photoelectric sensor requiring 7 m sensing and an M12 connector, the corresponding model is the E3S-AT36. The stated sensing target is an opaque object with a minimum diameter of 10 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 without icing or condensation. Power-supply reverse polarity and output short-circuit protection are listed. Its specification also suits searches for an Omron 7 m PNP sensor and Omron long range through beam sensor. For the corresponding NPN E3S version with M12 connection, see E3S-AT16.
