The PI200M-A4 is suitable for scanning A4 size (216 mm) documents with 8 dots per millimeter resolution. Applications include document scanners, mark readers, and other office automation equipment. Functional Description The PI200M-A4 imaging array consists of 27 sensors, PI3020 produced by Peripheral Imaging Corp. The sensor is a monolithic chip with an array of 64 photo sensing elements, of which 27 are cascaded to provide 1728 photo-detectors. These cascaded chips are contiguously aligned in a single row and bonded to PCB.
