FAQs
The connector uses a square flange receptacle with a straight adaptor and a 1/3 bayonet coupling. It ships with solder cup contacts loaded for immediate use, enabling rapid, secure mating, simplified field wiring, and reliable electrical continuity in vibration-prone environments.
Yes. It operates from -40 °C to 125 °C, supporting performance in extreme cold and hot environments. The aluminium shell provides a weight-efficient structure, while the cadmium plating offers corrosion resistance, helping maintain contact reliability across cycles in harsh settings.
Applications requiring a dense signal/power interface in aerospace, defense, and rugged industrial machinery benefit most. The 32-contact layout supports complex harnessing, while solder cup contacts deliver robust, repair-friendly connections suitable for panel-to-harness junctions and field wiring.
The 85100A2232P50 is MIL-DTL-26482 SI qualified, indicating military-grade mating performance. It also uses REACH-compliant materials, aligning with environmental regulations and safe handling practices in many global markets.
The straight backshell adaptor simplifies alignment during mating and reduces installation time. Delivered with the connector, it minimizes parts handling and procurement steps, lowering labor costs and enabling faster system integration in production and field-service scenarios.
