MIL-DTL-26482 SI qualified design delivers proven interchangeability and minimizes design risk, translating to reduced program schedule impact and faster integration in aircraft and rugged equipment. The eight solder cup contacts enable robust, low-resistance connections suitable for high-reliability systems, reducing maintenance rework and rework-related downtime. Cadmium plating coupled with an aluminium shell provides corrosion resistance and lighter weight, improving long-term durability in outdoor or humid environments while supporting weight targets on aerospace panels. A straight backshell with an adaptor option and a 1/3 bayonet coupling supports rapid mate/disconnect and simplifies installation in constrained spaces, cutting assembly time and labor costs. Delivered with connector and N orientation, this receptacle offers consistent geometry for multi-dock enclosures and standardized field replacement, streamlining procurement and inventory management in high-mix manufacturing environments.

FAQs
For proper installation, align the N-oriented receptacle with its mating plug, use the straight backshell adaptor to simplify panel routing, and ensure solder cup contacts are clean and wetted for reliable joints. The 48 mm length and 26.5 mm width/height must fit the panel cutout, while the 8-contact layout supports the required signal/power density.
Yes. This part is MIL-DTL-26482 SI qualified, part of the Souriau 851 series, and is designed to mate with compatible 8-position square flange interfaces. Its solder cup contacts and cadmium-plated aluminium shell are specified to maintain performance in MIL environments while meeting SI qualification expectations.
The receptacle operates across -40 °C to 125 °C, offering reliable performance in extreme aerospace and industrial settings. It also complies with REACH environmental standards, supporting regulatory requirements for long-term field deployments and reducing compliance risk in global programs.
The 85100AC128P50 is a square flange receptacle designed to mate with matching 851-series plugs featuring a 1/3 bayonet coupling. It uses pin (male) solder cup contacts and comes with a straight backshell adaptor, facilitating straightforward mating in constrained enclosures and enabling rapid field replacement when needed.
The 851 series provides standardization across programs, reducing inventory complexity and part proliferation. Its MIL-DTL-26482 SI qualification, corrosion resistance, and vibration tolerance translate to lower maintenance costs, fewer unplanned downtime events, and longer service life in harsh environments. The combination of lightweight aluminium shell and cadmium plating also contributes to overall system efficiency and payload considerations.
