MIL-DTL-26482 SI qualification ensures aerospace-grade reliability, translating into lower rework rates and higher mission readiness for defense and avionics programs. The 16-position layout with solder cup contacts enables dense, clean harnessing, reducing wiring complexity and panel footprint while improving electrical performance under vibration. The 1/3 bayonet coupling provides quick, secure mating, speeding replacements in service fleets and minimizing downtime during maintenance windows. An aluminium shell delivers strength with light weight, improving overall system efficiency in portable or airborne equipment. The backnut design simplifies panel installation and reduces the risk of loose fittings in demanding environments. Cadmium plating offers robust corrosion resistance in challenging climates, supporting longer service life even in humid or salty atmospheres. Delivered with connector, the assembly process is streamlined, decreasing part-counting and test iterations. All these factors combine to lower total cost of ownership through faster install, fewer field failures, and longer mean time between failures in critical systems.

FAQs
Begin by aligning the receptacle with the panel cutout using the X orientation. Thread the backnut onto the rear of the panel and tighten to specification to seat the backnut securely. Mate the contacts by aligning the 1/3 bayonet coupling and twisting to lock, ensuring the solder cup contacts align with the harness pins. Verify the shell is clean and free of debris before final mating and seal as required for environmental protection.
The 85100E2016PX50 is MIL-DTL-26482 SI qualified, featuring a backnut, 16 solder cup male contacts, and a 1/3 bayonet coupling for secure, vibration-resistant mating. Its aluminium shell size 20 and cadmium plating support robust mechanical and environmental performance, making it well-suited for aerospace, defense, and other rugged MIL-spec deployments where reliable connectivity matters.
Yes. The receptacle is rated for an operating range from -40 °C to 125 °C, enabling reliable performance in extreme cold and hot environments. This wide temperature tolerance, combined with MIL-DTL-26482 compatibility, helps ensure consistent electrical contact integrity and mechanical stability across mission-critical scenarios.
Cadmium plating offers corrosion resistance in challenging environments, but care should be taken to prevent abrasive wear and to minimize exposure to corrosive media beyond specified limits. Regular inspection for signs of coating wear or corrosion is advised, and compatibility with REACH needs to be ensured in your supply chain and maintenance practices.
The product specifies REACH environmental compliance, alongside MIL-DTL-26482 SI qualification, which supports usage in regulated environments. When planning deployments, verify that your overall assembly materials and harnesses also comply with REACH and any site-specific environmental requirements to ensure seamless certification and field readiness.
