DESCRIPTION

D38999/26FH35SA is a MIL-DTL-38999 Series III subminiature connector featuring a threaded 360° turn coupling mechanism and environmentally sealed design for harsh environment applications. The connector is available with stainless steel, aluminum, or composite shell materials, with multiple plating options including electroless nickel, nickel PTFE, black zinc-nickel, and olive drab cadmium to meet corrosion resistance requirements. It supports up to 187 maximum signal contacts with standard contact sizes of 23, 22, 20, 16, 12, 10, and 8, accommodates shell sizes 9 through 25, and offers contact styles including crimp, solder cup/eyelet, and PCB tail configurations. The connector operates across a temperature range of -65°C to +200°C (depending on shell finish), provides 500 mating cycles of durability with higher-cycle versions available, and includes features such as scoop-proof design, hermetic versions, filter versions, and spring fingers for EMI control. Standard configurations include straight plugs with EMI spring fingers and lanyard release options, as well as receptacles with box mounting, wall mounting, jam nut, solder mount, weld mount, and through-hole bulkhead options, making it ideal for aerospace, defense, and marine connectivity solutions requiring environmental sealing and robust performance.
