DESCRIPTION

D38999/26FD97PN is a MIL-DTL-38999 Series III subminiature connector designed as a straight plug with EMI spring fingers for rugged, harsh environment applications in aerospace, defense, and marine industries. The connector features a threaded 360° turn coupling mechanism and is environmentally sealed with scoop-proof design, offering hermetic and filter versions for enhanced protection. It supports multiple shell materials including stainless steel, aluminum, and composite, with various plating options such as electroless nickel, nickel PTFE, black zinc-nickel, and olive drab cadmium to meet specific corrosion resistance requirements. The connector operates across a wide temperature range of -65°C to +200°C (depending on shell finish), accommodates up to 187 signal contacts with AS39029 contact type, and provides contact styles in crimp, solder cup/eyelet, and PCB tail configurations. With a standard durability rating of 500 mating cycles and available shell sizes from 9 to 25, this connector is ideal for mission-critical applications requiring reliable electrical connectivity in demanding environmental conditions.
