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.
zApplications
Image scanners (i.e. business card), detection sets (e.g. surface, paper edge, paper type)
zFeatures
1)25in/s (635mm/s) read speed (monochrome)
2)Bidirectional reading capability
3)54mm read width (70mm total width)
