Applications

MIL-DTL-38999 Series III is the thread-coupled, scoop-proof circular connector standard used across aerospace, defence and high-vibration industrial platforms. The Tri-Start coupling needs only a fraction of a turn to fully mate yet cannot loosen under vibration because of the anti-decoupling ratchet. Class W (olive drab cadmium over aluminium) is the most widely specified finish and gives 500 h of salt-spray protection. The contact-variant letter before the key position is P for pin and S for socket; A/B are the contact-less versions of each. Airoadcon builds the same shell threads, insert arrangements and keyway positions, so a J599/ number intermates with the Amphenol, TE Deutsch and Souriau equivalents listed above.
