FAQs
Install the square flange receptacle by aligning the 61‑position cavity layout with the mating plug, securing the square flange with appropriate fasteners, and ensuring the backshell adaptor is properly seated. Use the X orientation to match the connector’s mating counterpart, and route the solder cup connections per your harness design to maintain signal integrity and vibration resistance.
Verify 61 contacts in a 61‑cavity layout, 1/3 bayonet coupling for quick mating, straight backshell, cadmium plating on an aluminium shell, and operating temperature range from -40 °C to 125 °C. Confirm the contacts are solder cup and male pin, and ensure the panel footprint matches the square flange receptacle design.
Yes. The 85100A2461PX50 is MIL-DTL-26482 SI qualified, designed for high-reliability aerospace and defense use. Its rugged aluminum shell, controlled cadmium finish, and REACH compliance support regulatory requirements while providing reliable mating under vibration and environmental exposure typical in these sectors.
Key standards include MIL-DTL-26482 SI qualification for military-grade performance and REACH compliance for environmental safety. The shell uses cadmium plating, and the assembly operates across -40 °C to 125 °C, suitable for demanding industrial or aerospace environments when paired with compliant harnesses.
The 85100A2461PX50’s high contact density and 1/3 bayonet coupling reduce mating time and wear, lowering field maintenance costs. Interchangeability with other Souriau 851 series parts simplifies replacements, minimizes inventory, and supports predictable lifecycle planning in long-duration programs.
