SE-20 Wide Gap Sensor

The SE-20 is ideal for highly reflective materials, as it is not affected by ambient light and reflections.

The SE-20 emits a pulsing light, hitting the edge of the strip and is reflected from the reflector installed below the strip. The material in the reflector polarizes the light it reflects to the sensor. These polarized light signals are processed to filter out ambient light and reflections to accurately define the position of the strip.
