FAQs
The 85100A833S50 is a MIL-DTL-26482 SI qualified square flange receptacle featuring 3 solder cup contacts, an aluminium shell, and a 1/3 bayonet coupling. It mates with appropriate Souriau 851 series plugs, uses the N orientation, and ships ready with connector assemblies, simplifying spares planning and reducing mis-mating risk in avionics and rugged industrial equipment.
This receptacle is rated for -40 °C to 125 °C, making it suitable for extreme environments such as aerospace and harsh industrial environments. The aluminium shell with cadmium plating contributes to durable performance, while the solder cup contacts provide reliable, soldered connections in constrained spaces.
Yes, the 85100A833S50 supports REACH compliance, aligning with European environmental requirements for chemical safety. This reduces regulatory risk for assemblies used in regulated sectors and ensures subassemblies and systems can meet purchasing and certification requirements without additional testing for compliance.
With a compact 41 mm length and a 21 × 21 mm footprint, plus straight back orientation and a 1/3 bayonet coupling, the connector enables fast mating and routing in tight panels. The N orientation simplifies cable planning, reducing installation time and potential misalignment during field upgrades or maintenance.
The 851 series is well-suited for aerospace, defense, and rugged industrial automation where reliability under vibration, temperature extremes, and regulatory compliance are critical. Features like solder cup contacts, square flange receptacle, and adaptor backshell support reduce life-cycle costs by enabling standardization, easy field repair, and rapid integration into existing harnesses.
