For the ISI System, our Capacitive Position Sensors have in-vacuum cables which require a certain type of feedthru flange to exit the vacuum system:  Triax Connector Feedthru Flange.

We recently had some of these flanges Class-A-ed, and wanted to use some of these down in the Staging Bldg.  One of these flanges was inspected and left on a table.  During clean-up, I moved it from the table on to one of our racks.  Yesterday, when pulling this part from the rack, I discovered that the flange was damaged beyond vacuum functionality.  In a nut shell, one (of 2) connectors was broken off the flange.  The connector is attached to the steel flange via a ceramic material, and this was the source of the vacuum failure for these flanges:  1 (of the 2) connectors must have been pushed enough to crack.  [see photos]

This is a bit scary, so we will want to exercise extreme care with these flanges/connectors/cables.  Is there strain-relief for the cables (could easily envision someone stepping on an in-air cable on the floor and potentially pulling against this delicate connector enough to cause the plug to fail mechanically fail. We should also be careful handling these flanges through all steps of their life (i.e. don't cram them together when they are bagged after clean & bake, don't store them in areas where they can be easily bumped, etc.)
