This document introduces ROHM's ultra-small contact image sensor heads, suitable for character recognition. This product has a small size and a deep focus point, allowing scanning of objects without close contact to the scanner's glass bed to prevent damage. It also features screw holes and alignment pins for convenient mounting. It is mainly used in detection equipment for surface, paper edge, and paper type detection.
The LSH2001-AA10A is an ultra‑small contact image sensor head designed for detection sets such as surface, paper edge, and paper type applications. Its deep focus point enables scanning without close contact to the glass bed, protecting both the object and the scanner.
The datasheet lists key characteristics including a 16.25 mm effective scanning width, 200 dpi dot density, 3.3 V power supply, 8 MHz clock, and operating temperature from –5 °C to 45 °C. Pin assignments, timing charts, and example peripheral circuits are also provided for integration into electronic equipment.
