Interpretation aid for the field of view diagrams
Using the diagrams, you can determine the following data for each device type:
•
The maximum working distance for a selected code resolution
•
The dimensions of the field of view that is available for this distance

Given (in red):
•
Code resolution for 2D code 7: 1.0 mm
•
Focal length of lens 8: 12.5 mm
Read off (in green):
•
Maximum working distance 9: approx. 1,400 mm
•
Field of view ß: approx. 800 mm x approx. 600 mm
Both axes of the diagrams must be interpreted linearly.

Mounting the device
Aligning the device with viewing window to object
Remember to consider the shape and alignment of the field of view in front of the
device.
