FCT Electronics catalog pages.

NOTE: European mfg. (like FCT) sell both 4-40 (English) and M3 (metric hardware).
Purchase correct size.
In addition to Sliding latch, you will also find plastic and metal dust caps.
That may be of interest for other Lucent RFTG-u owners.
CAUTION: D-subminiature latches should only be used in permanent or non-mobile equipment. WHY?
I watched computer equipment (tens of thousands of $$) -- dropped to floor --
by the pulling of cable (wiring tech -- reassigned after incident).

> Hello, I’ve been using regular D-subminiature shells (DE-9 size) to hold the power connector onto the REF0 and REF1 and they come loose when I mess with the units. I’ve been looking all over today and can’t find the specific shell type that I need to use to clamp onto the D-sub connector.
> The REF0 and REF1 have small round discs that probably use a shell that is more of a clamp opposed to a screw-down type. Where can I find the proper D-sub shells?
