•
In mounting situations with strong vibrations, shock mounts may need to be pro‐
vided
•
Mounting options must be available for the 4 threaded mounting holes or the two
sliding nuts

Working distance
The possible working distance is 70 mm to 2,000 mm, depending on the application
and the device type. The working distance is measured starting from the housing edge.
The field of view is determined by the focus position, focal distance of the lens, and the
working distance. The necessary working distance can be determined based on the
field of view diagram (
see "Field of view diagrams", page 23

Mounting bracket and reflection prevention
In order to avoid reflections from the surfaces to be scanned, mount the device so that
it is tilted from the perpendicular to the surface.

Typical angle 20°
Depending on the application, an angle of between 0° (bright field light) and 45° (dark
field light) may be advisable.
5.3.3
Field of view diagrams
Take into account the following aspects in application design:
•
Field of view geometry of the device and position of the field of view in the space
in front of the device
•
Possible angles at which the objects can occur with respect to the device
•
For the planned working distance: resultant field of view length and width and
approximate resolution
