Maintenance teams planning replacements for E3S-AR36 frequently review Omron SMPS 24V 10A, E3Z D61 2M and Omron Sensors to prevent downtime, checking availability and compatibility with existing systems.
Omron E3S-AR36 Photoelectric Sensor
The Omron E3S-AR36 Photoelectric Sensor is a medium photoelectric sensor with built-in amplifier, retro-reflective with M.S.R. function, and provides a 2 m sensing distance using the E39-R1 Reflector. It operates on a 10β30 VDC power supply and belongs to the Omron automation lineup under the Omron Photoelectric Sensors category and the Omron E3S Series. Featuring a red LED (660 nm) light source, PNP output, M12 connector, Light-ON/Dark-ON selectable mode, and 0.5 ms response time, this model ensures stable detection of opaque objects (75 mm dia. min.) with 30 mA current consumption and IEC IP67 protection for industrial reliability.

The Omron E3S-AR36 delivers a reliable sensing distance of 2 meters using a retro-reflective method and a Red LED (660 nm) light source. It is optimized for detecting opaque objects as small as 75 mm in diameter, making it suitable for packaging lines, conveyor systems, and object presence detection in factory automation. The sensor operates efficiently with a 10 to 30 VDC power supply and PNP output configuration, consuming just 30 mA plus 15 mA with turbo mode.
Designed for flexibility, the E3S-AR36 Photoelectric Sensor offers a selectable Light-ON/Dark-ON operation mode, a fast 0.5 ms response time, and sensitivity adjustment using a two-turn endless adjuster with visual indicators. The rugged design includes a durable PBT housing with stainless steel (SUS304) components and a secure M12 connector. It is built to withstand industrial challenges with IP67 and NEMA 4X (indoor) ratings, strong resistance to vibrations and shocks, and a wide operating temperature range from β25Β°C to 55Β°C.
This sensor is trusted for its performance, durability, and safety features such as reverse polarity protection, short-circuit protection, and mutual interference prevention.
