MIL-DTL-26482 SI qualification provides a robust baseline for rugged environments, reducing qualification time and enabling smoother program milestones. The 32-contact layout offers high-density routing in a compact footprint, supporting complex I/O networks while preserving panel space. Solder Cup contact delivery ensures reliable, field-serviceable terminations with minimal tooling, and the 1/3 Bayonet coupling delivers fast, repeatable mating in tight installations. A straight backshell with backnut simplifies mounting in constrained chassis, improving vibration resistance and overall reliability in aerospace, military, and industrial automation. Cadmium plating on an aluminium shell delivers corrosion resistance and thermal performance across the specified -40 °C to 125 °C range, while REACH compliance aligns with modern environmental standards. Delivered with connector and X-oriented configuration streamlines integration with existing Souriau 851 components, reducing spares variety and procurement effort.

FAQs
Installation centers on aligning the 32-contact square flange with the mating plug, securing the backnut backshell, and ensuring proper orientation (X). The solder cup contacts require clean, flux-compatible terminations, and the 1/3 bayonet coupling enables rapid, repeatable mating. Use corresponding Souriau 851-series components to maintain compatibility and ensure IP/environmental performance expectations are met.
Key specs include operating temperature from -40 °C to 125 °C, cadmium plating for corrosion resistance, an aluminium shell, and 32 contacts with solder cup delivery. The backnut backshell and straight orientation support stable, vibration-resistant mounting, while MIL-DTL-26482 SI qualification guarantees heritage performance in defense and aerospace applications.
Yes. It is designed for seamless interoperability within the Souriau 851 family, featuring the same 32-contact density, backnut backshell, 1/3 bayonet coupling, and X orientation. Using a consistent family reduces spare parts variety, simplifies procurement, and ensures reliable mating with existing 851-series plugs and panels.
This receptacle is MIL-DTL-26482 SI qualified and REACH compliant. The cadmium plating provides proven corrosion resistance, while the aluminium shell offers light weight and strength. These certifications support regulatory compliance in aerospace and industrial sectors and help streamline supplier qualification processes.
Plan for periodic inspection of solder terminations and mating interfaces to prevent contact wear. The 1/3 bayonet coupling enables repeatable mating, but ensure proper latching to maintain vibration resistance. Stock compatible Souriau 851 series connectors to minimize downtime during field replacements and to maintain consistent electrical and environmental performance over the lifecycle.
