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

For the In-Sight 9902L vision system, the C-Mount lens has the
following restrictions:
l
Maximum thread length is 5.25mm.
l
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
19.25mm. If the C-Mount lens threads and body protrude
more than 6.5mm, you can add a spacer between the lens

working distance.

77mm, the maximum lens body diameter is 55mm and the maximum
diameter including locking screws is 55mm.

adapter screws and tighten; the maximum torque is 0.90 Nm (8 in-lb).
4. Thread the lens into the vision system.
