LSH2004-AA20A_11

Contact Image Sensor Heads for narrow-width scanners LSH2004-AA20A Compatible with A6 size media, feature a dual-arch structure, allowing straight pass reading (both-directions). In addition, they are compact, measuring only 119.5mm in length. 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) Proprietary prism maintains a uniform output signal. 4) Ceramic substrate used, ensuring excellent dimensional and thermal stability. Dimensions (Unit : mm) 5.5±0.3 119.5±0.3 2.5 109.6 (Effectiv Reading Width :104.6) 3.96±0.5 5±0.1 φ2±0.05 (Depth 1) Paper Feed Direction C L No.1 Pixel 17.5±0.25 12.5±0.05 60±0.3 A 29.75±0.3 10.7±0.4 25±1 Max. 1.5 15.5±1 (12.9) (3.8) No.9 No.1 (NOTE 1) Deflection at the top of glass:0-0.25 Projection to platen is positive.
