FAQs
Use the square flange mounting pattern with the straight backshell adaptor. Ensure correct Y orientation for harness routing and secure mating with the 1/3 Bayonet coupling to resist vibration in aerospace and industrial environments.
It provides 27 solder-cup contacts loaded in a 27-cavity layout, uses cadmium plating on an aluminium shell size 20, and operates from -40 °C to 125 °C with a straight-backshell configuration and 1/3 bayonet coupling.
Yes. It is MIL-DTL-26482 SI qualified, REACH compliant, and designed for high-density interconnects with reliable mating and corrosion resistance in demanding environments typical of aerospace and industrial automation.
The 1/3 Bayonet coupling enables quick, secure mating and un-mating with minimal torque, reducing downtime during field servicing and panel changes while maintaining strong mechanical retention.
Interchangeability within the Souriau 851 family lowers spare-part inventory and qualification effort, while robust environmental performance and fast field servicing translate to higher uptime and lower total cost of ownership in mission-critical systems.
