Before procurement teams confirm E3S-AT61-2M, they typically review Omron SMPS 24V 10A, E3Z D61 2M and Omron Sensors to double-check performance ratings, stock availability, and supplier credibility carefully.
Omron E3S-AT61 2M Photoelectric Sensor
The Omron E3S-AT61 2M Photoelectric Sensor is a medium sensor with built-in amplifier, through-beam vertical type offering a 7 m sensing distance and NPN output with a 2 m pre-wired cable. It operates on a 10β30 VDC power supply and is part of the Omron automation range under the Omron Photoelectric Sensors category and the Omron E3S Series. Featuring a red LED (660 nm) light source, it detects opaque objects of 10 mm dia. minimum with 0.5 ms response time, Light-ON/Dark-ON selectable mode, and IEC IP67 protection ensuring high reliability. The Emitter and Receiver consume 20 mA max. (plus 15 mA with turbo function), with a 30 VDC load voltage and 100 mA max. load current for efficient industrial performance.

The Omron E3S-AT61 2M leverages a reliable through-beam sensing method with a generous sensing distance of 7 meters, capable of detecting opaque objects as small as 10 mm in diameter. Using a Red LED (660 nm) light source, it ensures accurate detection across long ranges. Designed for stability, the sensor operates on 10 to 30 VDC with an NPN output and supports a rapid 0.5 ms response time, making it suitable for fast-paced automation applications.
The emitter and receiver each consume a modest 20 mA, with an optional turbo mode drawing slightly more power for enhanced signal reliability. Installation is simplified with a pre-wired 2-meter cable, and the Light-ON/Dark-ON selectable operation along with a two-turn endless sensitivity adjuster provides operational flexibility. Built with rugged PBT and stainless steel (SUS304), the housing resists vibration, shock, and environmental stress. With a protection rating of IP67 and compliance with NEMA 4X (indoor only), it performs reliably even in dusty or humid conditions.
Equipped with reverse polarity protection and output short-circuit protection, the Omron E3S-AT61 2M Photoelectric Sensor is a trusted component in mission-critical sensing applications.
