Designed with a through-beam sensing method, the Omron E3S-AT36 offers a sensing distance of 7 meters, making it well-suited for detecting opaque objects as small as 10 mm. It features a Red LED (660 nm) as the light source, providing reliable detection across long distances. The sensor operates on a 10 to 30 VDC power supply, supports PNP output configuration, and delivers a fast 0.5 ms response time—perfect for time-critical industrial systems.
Both the emitter and receiver consume just 20 mA, with an optional turbo mode drawing an additional 15 mA for enhanced performance. The sensor includes a two-turn endless sensitivity adjuster with indicator, allowing precise configuration based on your environment. It supports Light-ON/Dark-ON selectable modes and is protected by integrated reverse polarity and short-circuit protection circuits. Built using PBT, denatured polyallylate, and stainless steel (SUS304), it’s housed in a rugged design that withstands vibration, shock, and temperature fluctuations.
Rated for IP67 and NEMA 4X (indoor only) environments, the Omron E3S-AT36 Photoelectric Sensor is trusted by engineers for its high durability and accuracy in harsh industrial conditions.
