MIL-DTL-38999 Series I connectors, designated as MS27505, are high-performance electrical receptacles designed for back panel and box mounting applications in harsh environments. Featuring a rugged aluminum shell with options for electroless nickel or cadmium olive drab plating, these connectors offer superior durability and corrosion resistance. With a total of 79 removable crimp contacts (22D), they provide reliable electrical connections in extreme conditions, operating flawlessly in temperatures ranging from -65°C to 175°C. The bayonet coupling mechanism ensures secure mating, while the C-keyway polarization prevents improper connections. Engineered to meet stringent military specifications, including environmental resistance and conductivity requirements, the MS27505 connectors are ideal for use in mission-critical aerospace, defense, and industrial applications.
