FAQs
Plan for a straight backshell adaptor installation with a 1/3 bayonet coupling to ensure fast mating and secure retention. Verify the N orientation and Cadmium-plated aluminium shell for corrosion protection in harsh environments. Ensure compatibility with Souriau 851 series mating components and allow clearance for 25 solder cup contacts to avoid bending or crowding of leads.
Yes. The 85100A2025P50 is designed as part of the Souriau 851 series family and shares common interfaces, including 25-contact layouts and bayonet coupling. For best results, pair with matching series receptacles and connectors to maintain channel integrity, consistent contact resistance, and uniform environmental sealing across assemblies.
It excels in aerospace, military ground equipment, and rugged industrial systems requiring reliable high-density interconnects. The 25-contact layout supports compact wiring in tight panels, while the -40 to 125 °C range ensures performance in temperature extremes typical of aerospace and heavy machinery installations.
Key considerations include MIL-DTL-26482 SI qualification for military-standard performance, REACH compliance for environmental safety, cadmium plating protection for corrosion resistance, and the operating temperature range of -40 to 125 °C. Confirm compatibility with your ESG and regulatory requirements and ensure the mating components meet similar specs.
Cadmium plating provides corrosion resistance that reduces maintenance cycles in humid or coastal environments, while the aluminium shell keeps weight down, improving fuel efficiency in aerospace and lowering handling costs in field deployments. The 25-contact, high-density design minimizes harness complexity, speeding installation and reducing downtime costs over the product’s service life.
