FAQs
The 85100A83AP50 is a square flange receptacle with a straight adaptor backshell designed for 21 mm by 21 mm footprints and a 41 mm length. It ships ready for connector mating with the 1/3 Bayonet coupling and N orientation, and is compatible with standard Souriau 851 series receptacles when used with the appropriate backshell and mounting hardware.
This receptacle provides 3 solder cup contacts (Pin/Male) in a 3-position layout, suitable for signal or low-current power paths in compact assemblies. The 1/3 Bayonet coupling supports reliable retention, while the aluminium shell and cadmium plating offer corrosion resistance and light weight for harsh environments.
Yes. MIL-DTL-26482 SI qualification, along with REACH compliance, makes this connector appropriate for aerospace, defense, and rugged industrial automation applications. Its compact form factor and robust coupling are well-suited for aircraft panels, military avionic enclosures, and tight-control cabinets.
The 85100A83AP50 is MIL-DTL-26482 SI qualified and REACH compliant, providing a high level of reliability and environmental responsibility. Cadmium plating is specified for the shell, which contributes to corrosion resistance in demanding environments.
With a lightweight aluminium shell, cadmium finish, and a 41 mm length, the connector supports easy replacement and reduced downtime. The 3-contact solder cup design minimizes the risk of loose connections, while the robust MIL-spec qualification helps stabilize procurement costs over the product lifecycle.
