MIL-DTL-26482 SI qualification ensures reliable mating in high-vibration aerospace and industrial environments, reducing field failures and warranty costs. The square flange receptacle form factor minimizes mounting footprint while maintaining robust alignment and EMI performance, supporting compact assemblies in confined equipment bays. A cadmium-plated aluminium shell delivers corrosion resistance in exposed or mission-critical settings, extending service life and lowering maintenance cycles. The 1/3 bayonet coupling enables fast, tool-free mating and un-mating, cutting installation and service downtime in production lines and field work. Eight solder-cup contacts provide strong, low-resistance circuits for power and signal paths, enabling reliable operation across varied harness configurations. Delivered with connector is a straightforward installation path, with a straight backshell adaptor that simplifies routing and cabling in tight spaces. The 851 series compatibility ensures scalable configurations, facilitating redesigns or upgrades without a complete system overhaul. This combination addresses common objections about weight, form factor, and environmental compliance while delivering measurable productivity gains.

FAQs
Installers should align the 2 cavity layout with the mating plug, verify the 1/3 bayonet coupling engages fully, and use the straight backshell adaptor to route cabling away from hot surfaces or moving parts. The solder cup contacts require proper tinning and secure crimping or soldering as per your wire gauge. Ensure the joint remains free of contaminants to maintain MIL-DTL-26482 compliance in service.
MIL-DTL-26482 SI qualification specifies stringent performance under vibration, temperature, and environmental conditions, translating to reduced contact wear and longer connector life. For defense and aerospace programs, this means lower maintenance intervals, fewer unplanned downtimes, and better predictability in mission-critical timelines, while still meeting REACH environmental requirements.
Yes. The MIL-DTL-26482 SI qualified design, combined with an aluminium shell and cadmium plating, supports operation from -40 °C to 125 °C and withstands substantial vibrational loads typical in aerospace and heavy industry. This makes it a dependable choice for applications where reliability under stress and temperature variation is essential.
The 85100A82PX50 is part of the Souriau 851 family and delivers compatibility with other 851-series receptacles and adaptors. Its straight backshell and 1/3 bayonet coupling are consistent with common mating interfaces, enabling straightforward integration into existing harnesses and enabling scalable system upgrades without reworking the entire interconnect network.
Maintenance is simplified by its robust MIL-DTL-26482 SI qualification and reliable solder cup contacts, which reduce failure modes and rework. The fast mating mechanism lowers service time, improving uptime in production or field environments. Over the lifecycle, this translates to lower maintenance costs, predictable performance, and stronger return on investment for critical equipment.
