Feature → Business Impact → Application: The 85100A128S50 uses MIL-DTL-26482 SI qualification to deliver high-reliability interconnects when vibration, temperature extremes, and mechanical shock are present, reducing unscheduled maintenance and failures in mission-critical systems. This translates to measurable uptime gains for aerospace harnesses and rugged industrial controls. Application: Aerospace flight controls, military ground vehicles, and offshore automation where consistent performance under stress is essential. Feature → Business Impact → Application: Eight contact positions in a socket (female) solder cup configuration within a compact aluminium shell support dense wiring and clean board-to-wire transitions, enabling compact panel layouts without sacrificing connection integrity. Application: Control panels for robotics, process automation, and defense electronics where space is at a premium. Feature → Business Impact → Application: Cadmium plating on an aluminium shell provides enhanced corrosion resistance and extended service life in harsh environments, reducing preventive maintenance and replacement costs. Application: Coastal or chemical processing facilities, outdoor installations, and equipment exposed to salt spray. Feature → Business Impact → Application: 1/3 Bayonet coupling with a square flange receptacle simplifies mating and improves vibration resistance, cutting assembly time and risk of misalignment during field installs. Application: Heavy-duty machinery and aerospace ground support equipment requiring fast, reliable coupling. Feature → Business Impact → Application: Delivered with connector and loaded contacts, plus N orientation, streamlining installation and ensuring consistent performance across assemblies. Application: Retrofit projects and new builds in industrial automation and defense sectors where standardization with Souriau 851-series parts is preferred.

FAQs
Yes. The 85100A128S50 is part of the Souriau 851 series and uses a square flange receptacle design with a straight backshell adaptor, ensuring straightforward mounting on standard Souriau panels. The 1/3 bayonet coupling provides rapid mating while maintaining secure retention in vibration-heavy environments.
The receptacle uses socket (female) solder cup contacts and operates from -40 °C to 125 °C. The 8-contact arrangement supports reliable signal and power transmission within rugged interconnect assemblies typical of aerospace and industrial machinery.
This part is well-suited for aerospace, defense, and rugged industrial automation due to MIL-DTL-26482 SI qualification, corrosion-resistant cadmium plating on aluminium shell, and a compact, vibration-resistant design that maintains connectivity under harsh conditions.
The connector is MIL-DTL-26482 SI qualified and features cadmium plating with an aluminium shell for corrosion resistance. It also references REACH environmental considerations. This combination supports regulatory compliance in demanding, regulated applications.
Delivered with connector and contacts already loaded, plus the straight backshell adaptor and N orientation, the 85100A128S50 reduces assembly time and field errors. Its robust materials and MIL-spec qualification help extend service life, lowering maintenance costs and improving total cost of ownership over the product life cycle.
