MIL-DTL-26482 SI qualification provides a clear compliance path, improving reliability in mission-critical platforms and reducing field failures and rework, particularly in aerospace, defense, and industrial automation. 14 solder-cup contacts form high-density, robust signal and power paths, enhancing panel-level performance and reducing harness complexity for instrumentation and control systems. The 1/3 bayonet coupling enables fast, repeatable mating in maintenance cycles, lowering downtime on aircraft panels and rugged equipment. The aluminium shell delivers a lightweight yet durable enclosure that supports weight-sensitive designs and corrosion resistance in challenging environments. A straight backshell with backnut ensures straightforward installation and reliable sealing, while the operating range of -40 to 125 °C broadens suitability across extreme climates. Delivered with connector reduces integration time and ensures consistency across spares and assemblies.

FAQs
The 85100E1214SW50 is a square flange receptacle with backnut and straight backshell, delivering 14 socket (female) contacts in a 14-cavity layout. It uses solder cup contacts and a 1/3 bayonet coupling, oriented for W configuration. It ships delivered with the connector, ensuring compatible mating with Souriau 851 series components and a robust, MIL-DTL-26482 SI qualified interface.
This receptacle is MIL-DTL-26482 SI qualified and features cadmium plating for corrosion protection, with an aluminium shell suitable for harsh environments. Operating temperature ranges from -40 °C to 125 °C, and REACH compliance is noted in the product specifications, supporting use in regulated industrial and aerospace settings.
Yes. The combination of MIL-DTL-26482 SI qualification, 14-cavity configuration, backnut-backed square flange receptacle design, and the rugged aluminium shell makes it well-suited for aerospace and defense equipment. Its field-serviceable features and 1/3 bayonet coupling facilitate reliable, quick mating in demanding platforms while meeting stringent industry standards.
A straight backshell simplifies alignment and mating during installation, while the backnut provides a secure sealing interface to the bulkhead or panel. This pairing reduces installation time, improves sealing integrity, and minimizes misalignment risk in dense avionics or rugged industrial housings, contributing to faster field servicing and reliable performance over the product life cycle.
The 85100E1214SW50’s rugged MIL-spec construction, cadmium plating, and solder-cup contacts reduce corrosion-related downtime and rework. Its lightweight aluminium shell plus long temperature range lowers thermal stress and wear, while the 14-cavity layout supports scalable channel counts. Overall, expect lower spare-part inventories, faster maintenance cycles, and improved system uptime in demanding environments.
