Fife SE-20 Wide Gap Sensor

• 

Using a pulsed LED, Fife’s SE-20 Wide-Gap Sensor is engineered for gaps up to 3 meters and is unaffected by ambient light or reflections, making it ideal for highly reflective strips.

Material in the reflector polarizes the light it reflects back to the sensor. These polarized light signals are processed to filter out ambient light and reflections to accurately define the position of the strip.
