BESCHRIJVING

The D38999/20WE99PN 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. This connector features a threaded 360° turn coupling mechanism, environmentally sealed construction, and scoop-proof design to ensure reliable performance in demanding conditions. The connector supports multiple shell materials including stainless steel, aluminum, and composite options, with various plating finishes such as electroless nickel, nickel PTFE, black zinc-nickel, and olive drab cadmium for enhanced corrosion resistance. It accommodates up to 187 signal contacts with standard contact sizes of 23, 22, 20, 16, 12, 10, and 8, using AS39029 contact types available in crimp, solder cup, eyelet, and PCB tail styles. Operating across a temperature range of -65°C to +200°C (depending on shell finish), with 500 mating cycles durability and higher durability versions available, this connector is ideal for mission-critical applications requiring environmental sealing, EMI control, and long-term reliability.
