Technical Datasheet: OMRON E3S-AR86

Product Type: Built-in Amplifier Retro-reflective Photoelectric Sensor (Vertical Mount)

Part Number / Model: E3S-AR86

Series: E3S-A Series (Medium Size High-Performance Sensors)

1. Product Characteristics & Application

• Sensor Type: Photoelectric Sensor

• Sensing Method: Retro-reflective with built-in Mutual Interference Prevention and Polarity-free Red Light source (660 nm Red LED).

• Sensing Distance: 0.1 to 2 meters (When paired with the standard E39-R1 reflector).

• Housing Shape & Orientation: Compact cuboid structural shape, optimized for Vertical mounting.

• Special Features: Equipped with M.S.R. (Mutual Interference Prevention / Modulated Scatter Reflective) function allowing it to reliably detect mirror-like or highly reflective targets without false triggering. Built with a two-turn sensitivity endless adjuster and a highly visible alignment indicator spot. Highly utilized in material handling tracking loops, sorting channels, conveyor networks, and general machine packaging lines.
