Install the C-Mount Lens and Cover (COV‑7000‑CMNT or COV‑7000‑CMNT‑EX)

Complete the following steps to install a C-Mount lens and cover to the vision system. The C-Mount covers (COV-7000-CMNT or COV-7000-CMNT-EX) are optional accessories and required for IP67 protection.

Note:

When using a C-Mount lens, the following restrictions apply:
- 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 and vision system. However, the spacer decreases the working distance.

If using the COV-7000-CMNT cover, the maximum lens length is 41mm, the maximum lens body diameter is 36.5mm and the maximum diameter including locking screws is 47mm.
If using the COV-7000-CMNT-EX extended cover, the maximum lens length is 62mm, the maximum lens body diameter is 36.5mm and the maximum diameter including locking screws is 46.5mm.

CAUTION: If installing a C-Mount cover, the illumination accessory (ISLM-7000-WHI) PCB should not be installed to the vision system. Refer to Remove the Illumination Accessory PCB for steps to safely remove the PCB and avoid damage to the vision system.

Remove the rubber faceplate covering the image sensor window, if present.
Remove the protective film covering the threaded lens opening, if present.
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).
Thread the lens into the vision system.
Attach the cover to the vision system. Rotate the cover clockwise approximately seven degrees to lock it.
