Application

D38999/26KB5SN is the Series III straight plug on the 11-5 insert — five size-20 contacts in a shell 11 body — built in class K, the stainless-steel shell variant of the 38999 class table rather than the usual aluminium with cadmium or nickel plating. The stainless shell is specified where the connector sees aggressive cleaning, salt exposure or elevated surface temperature and the plating of a W or F class part would be the first thing to fail. The plug carries the Tri-Start threaded coupling ring with ratchet, so it mates with any Series III receptacle of the same shell size and insert, including the /20 wall-mount and /24 jam-nut receptacles. It is bought by DLA as a plug connector line item (solicitation SPE7M4-27-U-0002), and class K parts are normally QPL-restricted, so the qualified source must be confirmed before quoting.
