Install the C-Mount Lens and Cover (COV-7000-CMNT-LG)
Complete the following steps to install a C-Mount lens and cover to the vision system. The C-Mount cover is an optional
accessory and required for IP67 protection.
Note :

When using a C-Mount lens, the following restrictions apply:
l
Maximum thread length is 5.25mm.

The C-Mount lens threads and body cannot protrude more than 6.5mm in length into the vision
system when screwed in unless the diameter of the back lens is smaller than 14.75mm. If the C-
Mount lens threads and body protrude more than 6.5mm, you can add a spacer between the lens
