MIL-DTL-38999 Series III / 8D Series
MIL-DTL-38999 Series III / 8D Series Connectors are high-performance circular connectors engineered for the most demanding aerospace, defense, and industrial applications. Featuring a patented self-locking threaded coupling mechanism, high contact density, excellent EMI shielding, and superior resistance to vibration, shock, and harsh environments, the 8D Series ensures secure and reliable signal, power, and data transmission in mission-critical systems.
The Souriau D38999 Series, also known as the 8D Series, is a high-performance circular connector family designed to meet the stringent requirements of aerospace, defense, and other harsh-environment applications. Fully compliant with major industry standards including MIL-DTL-38999 Series III, EN3645, BACC63, and CECC, the 8D Series delivers exceptional reliability in the most demanding operating conditions.
Available in a choice of aluminum, composite, titanium, stainless steel, and bronze shells, along with multiple plating options, the 8D Series offers excellent resistance to corrosion, shock, vibration, fire, and mechanical wear. This broad range of materials enables engineers to select the optimal solution for virtually any mission-critical application.
Built around the MIL-DTL-38999 Series III design, the connector incorporates Souriau’s patented self-locking mechanism, visual mating indication, scoop-proof contact protection, quick threaded coupling, and 360° EMI shielding. The combination of the self-locking technology and metallic contact retention system ensures secure electrical performance even in environments exposed to extreme vibration, shock, and rough handling.
