Feature MIL-DTL-26482 SI qualification; Business Impact: ensures regulatory compliance and mating integrity in mission-critical assemblies; Application: aerospace, defense, and high-reliability industrial equipment. By aligning with recognized standards, you reduce compliance risk and streamline supplier qualification. The 85100AC1626SW50 part demonstrates strict quality control and traceability, supporting long-term performance in harsh environments while preserving interchangeability with existing Souriau 851-series interfaces. Feature 26-contact layout within a 51 mm length; Business Impact: high-density connectivity without enlarging the footprint, simplifying routing and harness design; Application: avionics bundles and rugged control panels. The 26 cavities are configured to support solder cup contacts, enabling robust, soldered terminations for vibration-prone installations. This combination translates into faster assembly, lower assembly error rates, and easier field serviceability. Feature Cadmium finish on an aluminium shell; Business Impact: corrosion resistance and lightweight construction for harsh environments; Application: outdoor, maritime, or aerospace applications where exposure is a concern. Cadmium plating provides robust protection while aluminium shell reduces weight and improves heat dissipation. Together, they extend component life, reduce maintenance cycles, and help meet environmental constraints such as REACH while maintaining attractive total cost of ownership. Feature Solder Cup contacts with loaded contact delivery; Business Impact: simpler termination, reliable solder joints, and quicker field upgrades; Application: assembly lines and retrofit projects. The receptor delivers with connector, oriented W, ensuring consistent mating orientation and quick cabling. The solder cup contacts improve electrical performance and reduce intermittent connections in vibration-rich environments. Feature 1/3 Bayonet coupling and straight adaptor backshell; Business Impact: secure latching and repeatable mating under vibration, plus straightforward installation; Application: equipment subject to dynamic loads such as aircraft, military, and industrial automation. The straight adaptor simplifies panel mounting, while the 1/3 bayonet mechanism provides tactile feedback and a robust seal, improving MTBF and reducing field maintenance.

FAQs
The 85100AC1626SW50 uses a 1/3 bayonet coupling and a straight adaptor backshell, with a W orientation for consistent mating. Typical installation requires conformal alignment prior to engagement and a secure panel mounting method. Pre-loaded solder cup contacts simplify termination, and delivering with the connector reduces assembly steps, improving install time and repeatability in vibration-prone environments.
Key performance specs include 26 contacts in a 51 mm length, operating temperature range from -40 °C to 125 °C, cadmium plating, aluminium shell, and 1/3 bayonet coupling for secure mating. The design supports solder cup contact terminations, ensuring reliable electrical connections under vibration. Compliance with MIL-DTL-26482 SI and REACH enhances regulatory confidence and long-term reliability.
Yes. The MIL-DTL-26482 SI qualification, 26-contact square flange receptacle format, and rugged cadmium-plated aluminium shell are tailored for aerospace, defense, and other high-reliability applications. The straight adaptor, W orientation, and loaded solder contacts deliver robust performance in harsh environments while maintaining interchangeability with existing Souriau 851-series interfaces.
The product meets MIL-DTL-26482 SI qualification and REACH environmental requirements, with cadmium plating and an aluminium shell chosen for corrosion protection and weight management. These certifications and materials choices reduce lifecycle risk and support compliance in regulated sectors while sustaining performance across temperature and vibration extremes.
The 1/3 bayonet coupling provides secure, repeatable mating that resists loosening under vibration, while the solder cup terminations offer robust electrical joints with minimal creep. The cadmium-plated aluminium shell resists corrosion, extending service life and reducing maintenance cycles, which translates to lower total cost of ownership in demanding operating conditions.
