Multi line sensor heads for Wide format Scanner LSH1208-BD70A Multi line Sensor heads(MLS) corresponding to high speed scan and to reading wrinkles and fold lines due to 6 output channels and dual light source. Newly developed shield-structure sensor IC improved anti-noise characteristic. Applications High speed reading equipment (i.e. document scanners, wide format scanners devices). Features 1) High speed reading capability due to 6 analog output. 2) Newly developed shield-structure sensor IC shuts out external noise. Moreover, it reduces malfunction due to applying electro-static as represented by IEC61000-4-2. 3) Reduction of shade due to wrinkles and fold lines by adopting dual light source.
