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.

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

lies in the optical path.

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 10-pin

with a 1.25mm pin space. It is a JAE 1L-Z-10P-S125T3-E. Its I/O designation is provided in Table 1. The location of Pin 1 is indicated

on the module outline.
