LSH2004-AA30A is a contact image sensor head from ROHM for use in narrow-width scanners. The sensor head features high-speed scanning (1000mm/s) and is compatible with A6 size media. It is a center connector type unit with no frame protrusion, simplifying assembly.
The LSH2004-AA30A is a contact image sensor head designed for narrow‑width (A6) scanners, offering high‑speed scanning up to 1000 mm/s. It integrates a signal amplifier, LED light source, and proprietary prism on a ceramic substrate for compact, stable performance.
The data sheet lists detailed electrical characteristics, pin functions, timing diagrams, and example inner and peripheral circuits, helping designers integrate the sensor into various image‑input devices such as check readers and card scanners.
