Contact Type Image Sensor
( 1/6 )
1.Application
This specification sheet is applied to Contact Type Image Sensor UA2B200AX.
2.
General Description
The UA2B200AX is a contact type image sensor with a valid pixel density of 200 DPI capable of
scanning an image at the rate of 250
s/line for 200 mm width. The video signal is outputted at the
8-bit long digital value and is provided with black and white output correcting function for each
pixel.
