( 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

µs/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.
