Contact image sensor heads Image sensor heads for Card-compatible IA2002-CE10A

ROHM’s IA2002-CE10A contact image sensor head utilizes a special ceramic substrate featuring superior dimensional precision and thermal dissipation characteristics, resulting in stable reading, even under fluctuating ambient temperature conditions. A unique prism, developed using the latest in optical technology, ensures simultaneous uniform light output and low light radiation to the media. In addition, bidirectional reading capability enables greater flexibility regarding carrier orientation.

z Applications

Image scanners (i.e. business card), detection sets (e.g. surface, paper edge, paper type)

z Features

1）25in/s (635mm/s) read speed (monochrome)

2）Bidirectional reading capability

3）54mm read width (70mm total width)

4）Color light source (switchable)
