Data Sheet

The PCB containing the imaging array is enclosed in a module housing along with a one-to-one graded indexed micro lens array, which

focuses the image of the scanned documents onto the sensing line of the sensor chips. The document is illuminated with an LED light

source, which is also mounted in the housing (see Figure 2).

Figure 2: AMIS-710252-A6 Cross Sectional View

This pictorial cross section shows the LED bar light source and its illumination path. The light on the document reflects images of the

document. The reflected images focus through the micro lens onto the image sensing line of the chips, where images are converted to

proportional electrical charges. An on board amplifier processes these signal charges into proportional video signal voltages, which are

sent out to the output video port.

All components are housed in a small plastic housing and covered with a glass window. This cover glass not only serves to protect all

of the critical components within the housing from dust, but along with the micro lens, it plays a minor role in the depth-of-focus because

it lies in the optical path.

4.0 Pin Out Description

There is one connector located at the end of the module. The outline of the module's housing in Figure 4 illustrates the connector

location. With the module window facing down on the flat surface, the viewer looking down on backside of the module and the

connector's pins facing viewer, the connector is located on the right-hand end of the module. The connector is a single row of ten pins

with a 1.25mm pin space. It is ECE EBW-PK23-P010L2-3Z. Its I/O designation is provided in Table 1. The location of Pin 1 is indicated

on the module outline.
