Omron E3S-R86 Photoelectric Sensor
The Omron E3S-R86 Photoelectric Sensor is a transparent object detection sensor featuring retro-reflective with M.S.R. function, 1 m sensing distance (using the E39-R1 reflector), and PNP output. It operates on a 10–30 VDC power supply and connects via a M12 connector. Part of the Omron automation range under the Omron Photoelectric Sensors category and the Omron E3S Series, this vertical type model features a red LED (660 nm) light source, Light-ON/Dark-ON selector switch, 1 ms response time, 30 mA current consumption, and durable IP67 protection for stable performance in demanding environments.

The Omron E3S-R86 supports retro-reflective sensing for transparent and low-reflective materials with a sensing distance of 1 meter. It uses a Red LED (660 nm) light source and operates on a 10 to 30 VDC supply with ripple tolerance of 10%. This PNP output sensor integrates easily into PLCs and control systems through a robust M12 connector, and offers selectable Light-ON/Dark-ON operation. The two-turn endless sensitivity adjuster enables precise detection, even for delicate materials like 0.7-mm LCD glass boards.
Engineered for durability, the E3S-R86 is rated IP67 for protection against water and dust, and it operates reliably in temperatures from 0 to 40°C. It resists vibration (10–55 Hz) and shock (500 m/s²), and is housed in tough polybutylene terephthalate and stainless steel (SUS304). Its compact design, low 30 mA current consumption, and fast 1 ms response time make it ideal for high-speed packaging lines, inspection systems, and transparent material sensing in manufacturing.
