FAQs
Yes. This square flange receptacle is designed for the Souriau 851 series and uses a 1/3 bayonet coupling with a straight backshell adaptor. It is delivered with the connector, ensuring compatibility with standard panel cutouts and widely used 851 accessories for streamlined integration.
The assembly provides three solder cup contacts in a 3-cavity layout, with a cadmium plating on an aluminium shell and a shell size of 12. It supports -40 °C to 125 °C operating temperatures and complies with REACH environmental standards, making it suitable for aerospace and rugged industrial applications.
Aerospace, defense, and rugged industrial automation are primary beneficiaries. The MIL-DTL-26482 SI qualification ensures reliable performance under vibration and environmental stress, while the square flange receptacle format and 1/3 bayonet coupling support high-density, sealed interconnects in aircraft, ground vehicles, and harsh manufacturing environments.
The 1/3 bayonet coupling enables fast, tool-free mating with strong retention, which reduces assembly time and the risk of misalignment. Combined with the adaptor backshell and square flange mounting, it facilitates reliable, repeatable connections in tight panel spaces and supports quicker field replacements when needed.
By consolidating three circuits into a single, MIL-spec interconnect with high vibration resistance and wide temperature tolerance, you reduce harness complexity and part numbers. The durable Cadmium-plated Aluminium shell minimizes corrosion risk, while REACH compliance and available accessories help standardize procurement, delivering lower total cost of ownership over multiple programs.
