FAQs
The 85100A2039SW50 is a square flange receptacle designed for panel mounting with a straight backshell. Verify the panel cutout matches the 20 shell size and ensure proper alignment using the W orientation. Use the 1/3 bayonet coupling for secure mating, and connect the 39 solder cup contacts with appropriate cabling to minimize impedance mismatches. Verify REACH compliance and surface treatments for environment-specific applications.
Yes, this receptacle is MIL-DTL-26482 SI qualified and purpose-built for MIL-spec assemblies. It supports a 39-contact configuration and is delivered as a complete connector with a solder-cup contact form. Harness compatibility includes standard 39-position terminations and cabling designed for aluminium shells with cadmium plating, enabling reliable mating across aerospace and industrial harnesses.
Ideal for aerospace and rugged industrial automation where compact, high-density connectivity and resistance to harsh environments are required. The combination of an aluminium shell, cadmium plating, and MIL-DTL-26482 SI qualification makes it suitable for avionics enclosures, control panels in harsh manufacturing environments, and field-deployed equipment requiring durable, interconnect reliability.
The 85100A2039SW50 carries MIL-DTL-26482 SI qualification and REACH compliance, supporting regulatory expectations for safety, performance, and environmental impact. When specifying for regulated programs, confirm project requirements around cadmium-containing materials and sourcing standards, and verify compatibility with your program’s environmental and aviation/aerospace guidelines.
The SI-qualified connector minimizes lifecycle risk in mission-critical systems by delivering reliable mating and resistance to environmental stress. It reduces maintenance downtime due to robust materials, straightforward installation, and predictable performance. Over a program lifecycle, this leads to lower total cost of ownership through fewer field repairs and simplified spares management.
