Contact Image Sensor Heads for Card-compatible

LSH2002-AA10A

ROHM’s LSH2002-AA10A Contact Image Sensor Heads 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.

Applications

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

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)
