The H3662 Line Scan Sensor is an edge, centerline, or width detecting IR sensor. Using IR light, it illuminates a retro-reflective tape (reflector), which is placed behind the web. The light returned by the reflector is imaged onto a linear array within the sensor. The H3662 compensates for uniform decay of the optics due to dust build-up or discoloration of the lens/reflector cover. An integrated micro-controller analyzes the signal from the array and detects the exact position of the web’s edges.H3662 Line Scan Sensor SpecificationsAnalog output1.0-5.0 V dc
