The MIL-DTL-26482 SI qualified design delivers assured mating performance in vibration-prone environments, reducing the risk of intermittent connections and field downtime. This translates to improved system reliability and lower maintenance costs for mission-critical assemblies in aerospace and defense programs. Cadmium plating on an aluminium shell provides robust corrosion resistance and durable EMI shielding, extending service life in harsh environments while maintaining lightweight hardware for airframe integration. The square flange receptacle with a straight backshell adaptor simplifies panel mounting, alignment, and installation, enabling faster assembly with fewer torque and fitment issues. The 3-position, 3-cavity layout using solder cup contacts supports clean, secure solder connections and reliable signal integrity in dense harnesses. The 1/3 bayonet coupling offers quick, repeatable mating under field conditions, improving technicians’ efficiency during installation and servicing. Compatibility with Souriau 851 series ecosystems helps maintain part commonality across programs, reducing spares inventory and training needs for technicians familiar with aluminium shells and cadmium-plated contacts.

FAQs
To install the 85100AC83PW50, align the square flange receptacle with the mounting panel, secure with appropriate fasteners, and attach the straight backshell adaptor. Ensure the 1/3 Bayonet coupling engages fully for a positive lock, and solder the male pins to the harness using the solder cup contacts. Verify orientation (W) and passivity of mating components before energizing the circuit.
Yes. The MIL-DTL-26482 SI qualified design provides robust mating performance under vibration and shock. The 1/3 bayonet coupling ensures repeatable engagement, while the aluminium shell and cadmium plating offer durable mechanical protection and corrosion resistance in demanding aerospace and defense applications.
The assembly supports 3 electrical contacts in 3 cavities, with solder cup contact types for secure field connections. It uses a straight backshell adaptor and a square flange receptacle design, optimized for compact harness routing and reliable signal integrity across the operating temperature range of -40 °C to 125 °C.
The 85100AC83PW50 is MIL-DTL-26482 SI qualified and features cadmium plating with an aluminium shell. It is REACH compliant, aligning with current environmental and safety standards for international aerospace and defense supply chains.
Using this connector can reduce rework and spares complexity due to commonality with the Souriau 851 series. Its durable materials and reliable mating minimize field failure rates, lowering maintenance downtime and extending mean time between failures (MTBF) for critical harnesses in aviation and defense platforms.
