MIL-DTL-26482 SI qualified design provides high-reliability interconnects for demanding platforms. This specification reduces integration risk and accelerates qualification testing in aerospace, defense, and advanced industrial automation programs. The 85100E145S50 is designed as a square flange receptacle that mates with 851-series components, ensuring MIL-spec compatibility and robust performance under vibration, EMI, and thermal cycling. The combination of a backnut, front-back orientation N, and cadmium plating delivers long service life in harsh environments. 1/3 Bayonet coupling enables fast, tool-friendly mating with secure retention during vibration. Business impact includes reduced installation time, lower labor costs, and minimized risk of misalignment during field servicing. Application contexts span aircraft panels, military consoles, and rugged industrial control cabinets where dependable, repeatable connections matter most. Backnut backshell type and straight orientation streamline panel mounting and alignment, simplifying installation in tight or dense assemblies. This design reduces assembly steps and rework while improving environmental sealing in dusty or humid environments. Application examples include cockpit panels, harness junctions, and equipment racks in harsh facilities. Contact delivery is loaded with solder cup contacts (socket female) for durable, soldered terminations. This approach minimizes field termination variability and improves lead integrity for long cable runs. The 5-position layout supports standard 5-conductor harnesses, while 5 cavities ("#16") provide organized, scalable channeling for signal and power. Material and environmental features balance weight, strength, and corrosion resistance. An aluminium shell size 14 with cadmium plating offers a lightweight, robust housing suitable for aerospace and industrial environments. The operating range of -40 °C to 125 °C broadens applicability across outdoor installations, industrial ovens, and mobile platforms. Delivering with connector, the 85100E145S50 supports straightforward sourcing and rapid deployment, while accommodating orientation N and backnut assembly for reliable field performance.
