FAQs
Key installation factors include using the backnut for secure panel mounting, ensuring correct connector orientation (N), and mating with the straight backshell to minimize alignment issues. The 34.5 mm depth and 36.9 mm width/height help plan enclosure fit, while 41 solder cup contacts require attention to soldering quality and strain relief at the panel edge.
The 85100E2041S50 is MIL-DTL-26482 SI qualified, providing MIL-spec mating performance under vibration and shock. Its aluminium shell and cadmium plating offer corrosion resistance, and operating temperatures from -40 °C to 125 °C extend usability into extreme aerospace and industrial environments. REACH compliance further supports environmental requirements for many programs.
Yes. The 85100E2041S50 is designed as part of the Souriau 851 series and uses a 1/3 bayonet coupling with a straight backshell, aligning with other 851-series receptacles and panel hardware. It ships delivered with connector and backnut, enabling consistent mating and streamlined integration with matching 851-series plugs and panels.
Key considerations include MIL-DTL-26482 SI qualification for military-grade performance and REACH environmental compliance. Cadmium plating provides established corrosion resistance but may require assessment against RoHS-like requirements in certain programs. Always verify program-specific standards and substitute materials if mandated by your contract.
ROI is driven by high reliability, reduced maintenance, and faster assembly. The 85100E2041S50 combines a robust MIL-spec design with straightforward installation and long-term durability in harsh environments, lowering downtime and replacement frequency. Although initial cost is higher than generic connectors, lifecycle costs are typically lower due to fewer field failures and simpler spare-part management.
