DESCRIPTION

D38999/42WB35PN is a MIL-DTL-38999 Series III subminiature connector designed for rugged, harsh environment applications in aerospace, defense, and marine industries. The connector features a threaded 360° turn coupling mechanism with environmentally sealed construction, scoop-proof design, and optional 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 corrosion resistance requirements. The connector accommodates up to 187 signal contacts with standard contact sizes of 8, 10, 12, 16, 20, 22, and 23, operates across a temperature range of -65°C to +200°C depending on shell finish, and provides 500 mating cycles with higher durability versions available. Contact styles include crimp, solder cup/eyelet, and PCB tail options, with configurations available for plugs (straight with EMI spring fingers, lanyard release) and receptacles (box mount, wall mount, jam nut, solder mount, weld mount, through-hole bulkhead). This connector is ideal for applications requiring reliable electrical connections in demanding environments where environmental sealing, EMI control, and long-term durability are critical.
