The Autowide Sensor AWL is used mainly for CPC (center position control) to detect the center line on a strip (web).

It can continuously control the center line at a constant position without changing the position of the sensor each time the width of the strip changes (large changes such as seams etc.). The AWL is a new generation of detector which uses a highfrequency LED as the projector and SPDs(silicon photo diodes) as the detector.
