FAQs
To confirm compatibility, cross-check the 85100A2025SW50 catalog number against your connector profile and MIL-DTL-26482 SI qualification requirements. Verify shell size, backshell type, and contact layout (25 positions) align with your enclosure and I/O panel. Confirm solder cup contact terminations match your PCB or wiring harness specifications and ensure the straight backshell orientation suits your mating plane.
The receptacle supports an operating temperature range from -40 °C to 125 °C, enabling reliable operation in cold-start and high-heat scenarios. This performance, combined with aluminium shell and cadmium plating, mitigates corrosion risk and maintains contact integrity under thermal cycling, reducing downtime and replacement costs in demanding environments such as aerospace and industrial automation.
Yes. The 85100A2025SW50 is designed for aerospace-grade interconnections, featuring MIL-DTL-26482 SI qualification, square flange receptacle geometry, and a robust 25-contact configuration. Its adaptability with straight adaptors and W orientation supports high-vibration environments, while the cadmium plating and aluminium shell help manage weight and corrosion resistance for both aerospace and heavy industrial machinery.
This receptacle carries MIL-DTL-26482 SI qualification and REACH environmental compliance, providing assurance for regulated operations. While not all regions require CE marks for every component, the MIL standard and REACH status help satisfy many aerospace, defense, and industrial procurement requirements, supporting traceability and regulatory alignment in global supply chains.
Benefits include reduced field failures due to MIL-DTL-26482 SI qualification, longer service life from corrosion-resistant cadmium plating and aluminium shell, and faster installation with the delivered-with option and straight backshell. These factors translate to lower maintenance costs, fewer reworks, and shorter project timelines, delivering tangible ROI in mission-critical systems.
