Applications

The D38999/26SD19PA is the straight cable plug of the shell 15 D-19 arrangement — 19 size #20 signal contacts, the general-purpose contact size for control, power-return and signal runs in military aerospace wiring. The trailing A denotes an alternate key position, which prevents a plug from mating with the wrong receptacle of the same insert arrangement on a shared panel. The class S shell uses a stainless steel body with a nickel plate rather than the aluminium/cadmium combination of class W, giving a harder, more corrosion- and abrasion-resistant housing for high-mating-cycle and exposed-installation applications.
