LSH2004-AA30A_11

Contact Image Sensor Heads for narrow-width scanners LSH2004-AA30A These image sensor heads feature high-speed scanning (1000mm/s) and are compatible with A6 size media. They are center connector type units with no frame protrusion, simplifying assembly. Applications Check readers, card scanners, and a variety of other image input devices. Features 1) Signal amplifier integrated into each sensor IC in order to eliminate external noise ; compatible with 3.3V interface. 2) LED light source mounted on the same substrate as the sensor chip itself, resulting in a more compact, lightweight package. 3) Utilizes proprietary prism for improved lighting efficiency. 4) Ceramic substrate used, ensuring excellent dimensional and thermal stability. Dimensions (Unit : mm) 124.0±0.3 5.5±0.5 109.6(Effective Reading Width:107.8) 8.0±0.5 2±0.2 5.6±0.2 2×2-φ2.2 (Depth 5) Paper Feed Direction 18.0±0.4 No.8 Pixel 14±0.2 10.5±0.4 60±0.3 A 62±0.3 32±0.3 No.12 (NOTE 1) Deflection at the top of glass:0-0.25 Projection to platen is positive.
