This document introduces the multi-line sensor heads (MLS) developed by ROHM, which are suitable for high-speed scanning and reading wrinkles and fold lines. The product features 6 output channels and dual light source, enabling high-speed reading and anti-noise characteristics. It is suitable for high-speed reading equipment such as document scanners and wide format scanners.
The LSH1208‑BD70A is a multi‑line sensor head (MLS) designed for high‑speed document and wide‑format scanners. It features six analog output channels and a dual light source to reduce shading from wrinkles and folds, and its shield‑structure sensor IC improves anti‑noise performance.
Key specifications include a 216 mm effective scanning width, 1200 dpi dot density, 3.3 V power supply, and an 8 MHz clock. The datasheet lists detailed pin assignments, timing charts for various DPI modes, and circuit diagrams for both the inner and peripheral circuitry.
