Multi Line Sensor Heads for Card-compatible
LSH2002-AA10A
ROHM's LSH2002-AA10A multi line 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. Applications Image scanners (i.e. business card), detection sets (e.g. surface, paper edge, paper type) Features 125in/s (635mm/s) read speed (monochrome) 2Bidirectional reading capability 354mm read width (70mm total width) 4Color light source (switchable) Dimensions (Unit : mm)
