LSH3004-AA20A

Multi Line Sensor Heads for narrow-width scanners LSH3004-AA20A Compatible with A6 size media, feature a dual-arch structure, allowing straight-pass reading (both-directions). In addition, it is 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. 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.
