Optical and Mechanical
Considerations

3.1 Mechanical Interface

The camera’s electronics are housed in an anodized aluminum case. See Figure 3 and
Figure 4.

3.2 Mounting

For maximum stability and best heat sinking, DALSA recommends mounting the camera
by its front plate. There are four M4 threaded holes and seven 4-40 UNC holes tapped
into the front plate for mounting or attaching heat sinking. Other mounting options
include M4 holes on the sides of the camera (stability increases with number of sides
used) and the tripod mount (least stable).

3.3 Environment

For best operation, the camera and cables should be shielded from environmental noise
sources. The camera should also be kept as cool as possible. Specified operating
temperature is 0-40° C. Mounting holes (see above) allow you to attach heat sinking.
