MIL-DTL-26482 SI qualification delivers proven reliability in severe conditions, reducing field failures and maintenance costs for aerospace, defense, and industrial equipment deployments. By pairing with the 851 series ecosystem, it enables certified cross-compatibility and faster field upgrades, accelerating program timelines. The 27-contact, solder-cup configuration supports dense wiring while maintaining signal integrity in compact panels, translating to smaller enclosures and lighter harnesses without compromising performance. Cadmium plating provides corrosion resistance in challenging environments, extending service life in humidity, salt spray, and temperature extremes. The aluminum shell with a size 20 footprint offers robust mechanical strength while keeping weight down, improving overall system efficiency and reducing transport costs. Straight backshell alignment and a 1/3 Bayonet coupling enable quick, secure mating even in restricted access layouts. Operating from -40 °C to 125 °C ensures reliability across extreme climates, while the square flange receptacle design simplifies panel installation and maintenance. Delivered with connector and ready for integration, this part supports rapid deployment and consistent quality across programs.

FAQs
The 85100A2027P50 uses a square flange receptacle with 27 cavities and a 1/3 Bayonet coupling, designed to be compatible with the Souriau 851 ecosystem. It supports straight backshells and an adaptor backshell, enabling straightforward integration into existing panels and harnessing without custom adapters.
Key specs include 27 solder cup contacts in a 27-cavity layout, cadmium plating on an aluminium shell, shell size 20, and overall dimensions around 44 mm depth, 36.9 mm width, and 36.9 mm height. The connector is a square flange receptacle with a straight backshell and N orientation, delivered with connector for easy installation.
Yes. It is MIL-DTL-26482 SI qualified, features a wide operating temperature range from -40 °C to 125 °C, and uses cadmium plating for extra corrosion resistance, making it well-suited for harsh aerospace, defense, and industrial environments.
Consider the straight backshell, adaptor backshell option, and the N orientation when planning mounting holes and mating direction. The 1/3 Bayonet coupling provides secure retention with quick mating, which is advantageous in tight spaces or when feeding cables through restricted panels.
Choosing this MIL-DTL-26482 SI qualified receptacle from the Eaton Souriau 851 series reduces field failures and maintenance, supports longer lifecycle performance, and enables standardized sourcing across programs. The combination of high contact density, lightweight aluminum shell, and proven environmental tolerance delivers cost savings through easier integration and longer service intervals.
