The product combines MIL-DTL-26482 SI qualification with cadmium plating to deliver reliable corrosion resistance in harsh environments, reducing maintenance costs and downtime for military and aerospace customers. The square flange backnut provides precise alignment and robust mounting, enabling faster panel installation and vibration resistance across airborne and ground-support equipment. With six solder cup contacts delivered pre-loaded, technicians benefit from streamlined terminations and reduced assembly risk, improving field reliability and traceability in heavy equipment. The 1/3 bayonet coupling enables quick mating and disconnection, cutting service time during routine maintenance or field troubleshooting. The aluminium shell, size 10, together with a -40 °C to 125 °C operating range, delivers lightweight strength and operational flexibility for temperature-extreme environments. Delivered with connector options enhances install-time predictability and harness compatibility across Souriau 851 series ecosystems.

FAQs
For installation, align the square flange with the mounting surface, insert the backnut, and thread until seated. Use the X orientation to ensure proper connector alignment, then engage the 1/3 bayonet coupling with a quarter-turn to mate. The pre-loaded solder cup contacts simplify termination; verify continuity with a multimeter after assembly. Always follow ESD precautions and use appropriate torque values for the backnut to avoid over- or under-tightening.
Yes. The receptacle is rated for an operating range from -40 °C to 125 °C, making it suitable for aerospace, defense, and rugged industrial applications. Cadmium plating provides enhanced corrosion resistance, while the aluminium shell keeps weight low and mechanical performance high. For extreme environments, ensure mating hardware and harness routing comply with additional program requirements.
The part features six solder cup contacts in a socket (female) configuration, designed for reliable terminations in compact harness assemblies. It is delivered loaded, so you can quickly connect to your backplane or harness. The 2.54 mm (approximate) spacing and 98-layout facilitate compact interconnects in confined enclosures, with the 1/3 bayonet coupling ensuring secure mechanical and electrical connection.
Key certifications for this part include MIL-DTL-26482 SI qualification and REACH compliance, addressing both performance under stringent military/aerospace specs and chemical exposure regulations. These credentials support procurement through regulated supply chains, ensuring traceability, environmental responsibility, and conformity to industry standards in defense, aerospace, and industrial applications.
Typical use cases include aerospace avionics harnessing, military ground-support equipment, and rugged industrial machines requiring reliable, vibration-resistant connections. ROI is driven by quick installation (backnut and 1/3 bayonet coupling), reduced maintenance due to corrosion resistance, and long service life under wide temperature swings. Compatibility with Souriau 851 accessories further lowers total cost of ownership through streamlined spares and upgrades.
