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 (COV-7000-CMNT-LG) is an optional accessory and required
for IP67 protection.
Note:
When using a C-Mount lens, the following restrictions apply.
l
If using the COV-7000-CMNT-LG cover, the maximum lens length is
l
77mm with a bandpass filter, the maximum lens body diameter is
55mm and the maximum diameter including locking screws is 55mm.
1. Remove the rubber faceplate covering the image sensor window, if
present.
2. Remove the protective film covering the threaded lens opening, if present.
3. Place the adapter on the faceplate of the vision system. Insert the four
adapter screws and tighten; the maximum torque is 0.90 Nm (8 in-lb).
4. Thread the lens into the vision system.
Maximum thread length is 5.25mm.
l
The C-Mount threads and lens body cannot protrude
l
greater 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 6.5mm length is exceeded, a spacer
can be added between the lens and vision system, however
the spacer decreases the working distance.
