Omron E3S-AT86 Photoelectric Sensor

Name: Omron E3S-AT86
Brand: Omron
SKU: E3S-AT86
Rating: 4.9 (4 reviews)

The Omron E3S-AT86 Photoelectric Sensor is a Medium Photoelectric Sensor with Built-in Amplifier, featuring Through-beam type detection, 7 m sensing distance, PNP output, and M12 connector models. It operates on a 10–30 VDC power supply and is part of the Omron industrial automation portfolio under the Omron Photoelectric Sensors category and the Omron E3S Series. Equipped with a red LED (660 nm) light source, it detects opaque objects of 10 mm diameter minimum. Both emitter and receiver consume 20 mA (plus 15 mA with turbo function) and deliver 100 mA max load current. With Light-ON/Dark-ON selectable mode, 0.5 ms response time, and IEC IP67 protection, it ensures high-speed, durable, and reliable industrial performance.

The Omron E3S-AT86 delivers stable and reliable detection through a through-beam sensing method with a maximum sensing distance of 7 meters, suitable for identifying opaque objects as small as 10 mm. Powered by a Red LED (660 nm) light source, the sensor ensures accurate positioning and detection even in high-speed automation setups. It operates on a standard 10 to 30 VDC power supply and supports PNP output configuration, making integration into PLC systems simple and effective.

With a swift 0.5 ms response time and selectable Light-ON/Dark-ON operation modes, this sensor adapts to dynamic line conditions. The emitter and receiver units each consume only 20 mA, and an additional turbo mode enhances performance in critical conditions. The M12 connector ensures secure and quick installation, while the two-turn endless sensitivity adjuster provides easy calibration.

Built for harsh environments, the Omron E3S-AT86 Photoelectric Sensor features a rugged housing made from PBT, denatured polyallylate, and stainless steel (SUS304), offering excellent resistance to vibration, shock, and environmental stress. It carries an IP67 and NEMA 4X (indoor only) protection rating and includes built-in reverse polarity protection and output short-circuit protection.
