DESCRIPTION

D38999/26FG35SN is a MIL-DTL-38999 Series III subminiature connector designed as a straight plug with environmentally sealed construction for rugged aerospace, defense, and marine applications. The connector features a threaded 360° turn coupling mechanism, stainless steel shell with electroless nickel plating (48-hour salt spray rated), and supports up to 35 signal contacts using AS39029 contact type with crimp, solder cup, or PCB tail termination options. Operating across a temperature range of -65°C to +200°C depending on shell finish, the connector provides scoop-proof design with optional EMI spring fingers and hermetic versions for enhanced environmental protection. With 500 mating cycles durability and multiple shell material options (stainless steel, aluminum, composite), this connector is ideal for high-reliability interconnections in demanding aerospace and defense systems requiring robust environmental sealing and electromagnetic interference control.
