It comes pre-wired with a 2 m cable and draws 30 mA max from the supply. ## How it compares to nearby order codes The E3Z-D61K uses the same IR LED but is diffuse reflective — it detects targets directly, not a reflector. If your application requires a reflector, the D81K is the correct choice. The E3Z-R81K is also retro-reflective but swaps the IR LED for a red 660 nm LED and has a longer nominal range. The D81K's wide 5–100 mm view is optimized for short-range area detection; which one fits depends on target distance and required spot size.","metaTitle":"Omron E3Z-D81K Photoelectric Sensor, Retro-reflective, 5-100","metaDescription":"Active production Omron E3Z-D81K retro-reflective photoelectric sensor, 860nm IR LED, 5-100mm wide view, 30mA, pre-wired 2m.

The D61K detects diffuse reflection from the target; the D81K requires a separate reflector.
