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.
