Omron E3S-DC Color Mark Photoelectric Sensor (RGB 3-LED, IO-Link, Diffuse Reflective)

Omron E3S-DC Color Mark Photoelectric Sensor (RGB 3-LED, IO-Link, Diffuse Reflective)

Color mark photoelectric sensor with RGB 3-color LED (Red 635nm + Green 525nm + Blue 465nm) for stable detection on glossy aluminum-vapor-deposited packaging, colorful printed packaging with subtle color differences, and packaging with lot-to-lot color variation.

Key features

  • Standalone diffuse-reflective M12 sensor (no fiber required) — compact 80×54×56mm zinc die-cast IP67 housing
  • Thin projection beam + large lens optics keeps detection stable even when workpiece tilts. 9x S/N ratio improvement vs E3ZM-V via 3-LED light source plus high-efficiency optical design
  • Hi dynamic range covers black to mirror-like surfaces without saturation
  • Easy 2-button teaching (MARK + BKGD) for quick setup
  • Push-pull (IO-Link models) or NPN output. 10-30 VDC
  • M12 4-pin connector
