Rohm LSH1004-AB10A Contact image sensor heads for narrow-width scanner Datasheet

Contact Image Sensor Heads for narrow-width scanners
LSH1004-AB10A
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.
