Mechanical Considerations
5-4 BASLER A302f
DRAFT
5.4 Positioning Accuracy of the Sensor Chip
On the A302f, the tolerance for the positioning of the sensor’s image area to the camera housing
is ± 0.3mm in the horizontal and vertical directions. Rotational positioning accuracy is as shown
in Figure 5-4. Reference position is the center of the camera housing.
Since the translational and rotational positioning tolerances depend on each other, the worst case
of maximum rotational and horizontal/vertical mis-positioning cannot occur at the same time.

5.5 Maximum Lens Thread Length on A302fc
As shown in Figure 5.5, when a C-mount lens is
used on an
A302fc, the thread length on the lens
must be less than 7.5 mm.
A302fc cameras
equipped with a C-mount lens adapter have an
internal IR cut filter. If a lens with a longer thread
length is used, the IR cut filter will be damaged or
destroyed and the camera will no longer operate.
Cameras equipped with F-mount lens adapters do
not have an internal IR cut filter.
Caution!
When a C-mount lens is used on an A302fc, the thread length on the lens must
be less than 7.5 mm. If a lens with a longer thread length is used, the camera
will be damaged and will no longer operate.
