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) Dimensions (Unit : mm) 10.42 2.5 5.5 (Depth1) 12.5 17.5 5.5 70 54(Effective Scanning Width) Max.2.3 15.5 25 No.9 Max.13.25 Max.1.5 35 No.1 Pin No. No.1 No.2 No.3 No.4 No.5 No.6 (NOTE 1) Deflection at the top of glass:0-0.25 Projection to platen is positive.
