This document introduces ROHM's LSH2004-AA10A sensor head product, which is suitable for any scanning applications that require rapid scanning of widths of up to A6.
The LSH2004-AA10A is a compact color contact image sensor head designed for rapid scanning of widths up to A6, suitable for photo‑graphic and other image‑input applications such as check readers and card scanners. It integrates an analog memory circuit and LED light source on a ceramic substrate for high dimensional accuracy and thermal stability.
The data sheet lists key electrical characteristics, pin functions, timing diagrams, and internal circuit details, enabling designers to incorporate the sensor into electronic equipment like audio‑visual devices, office automation, and communication equipment.
