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.

Ceramic substrate used, ensuring excellent dimensional and thermal stability.
