FAQs
To install, align the square flange receptacle with the panel cutout, mount using the flange hardware, and secure the backshell adaptor with the provided adaptor. Ensure Z orientation is correct for mating with the corresponding plug, and verify that the solder cup contacts are properly tinned before final mating. The compact 44 x 40 x 40 mm footprint and 54 g weight support installation in constrained spaces without compromising seal integrity.
MIL-DTL-26482 SI qualification confirms conformance to a recognized military specification for high-reliability connectors, including environmental and mechanical performance under vibration and temperature cycling. Combined with aluminium shell, cadmium plating, and 36 solder cup contacts, the 85100A2236SZ50 is designed for aerospace-grade durability and consistent mating integrity in demanding flight and ground-support environments.
Yes. The 85100A2236SZ50 is part of the Souriau 851 series and shares common design language, including backshell options, coupling mechanisms, and contact configurations. This compatibility simplifies system integration, enables modular harness designs, and supports scalable solutions across platforms that rely on proven MIL-spec connectors.
The product is REACH compliant and employs cadmium plating for corrosion protection, suitable for harsh environments. The operating temperature range of -40 °C to 125 °C covers extreme cold and high-temperature operation, making it appropriate for aerospace, defense, and industrial automation where environmental exposure is a concern.
By delivering reliable MIL-spec performance with 36 solder cup contacts in a compact form, the connector reduces downtime from mating failures and field repairs. The square flange design and 1/3 Bayonet coupling enable faster installations, while the aluminium shell and cadmium finish extend service life in challenging environments, lowering total cost of ownership over the system’s lifetime.
