General Description

The PI627MC-A4, PI628MC-A4 and PI629MC-A4 are a family of Contact Image Sensor (CIS) modules,

using MOS image sensor technology for high-speed performance and high sensitivity. They contain a

complete optical imaging system that includes the light source and focusing elements.

The modules’ contact image sensor is divided into four sections, each with its own video output and identical

processing circuits allowing for high scanning speeds. Each module comes with its own particular LED light

source, which have different maximum light power outputs. Since the light power limits the exposure, which

is proportional to the product of scanning speed and light power, each module will have a different maximum

scanning speed and signal output voltage.

The modules can be used for scanning A4 size (216 mm) documents with 23.62 dots per millimeter

resolution. Applications include document scanning, mark readers, gaming and office automation

equipment.
