D38999/24WG39SN is a MIL-DTL-38999 Series III connector — the scoop-proof, triple-start threaded-coupling family that has become the default circular interface for avionics, ground vehicles, marine and deployable systems. Shell size 21 on arrangement 21-39 provides 37 x #22D + 2 x #20. The 'N' suffix denotes normal polarisation; alternate keys A-D rotate the insert so two adjacent connectors on the same rack cannot be cross-mated. Class W sets the finish and therefore the salt-spray and conductivity performance. Airoadcon ships the form-fit-function equivalent, including the cross-brand J599 build, with sample quantities for qualification testing.
