FAQs
The 85100AC1811SX50 uses a square flange receptacle with a straight backshell adaptor and 1/3 bayonet coupling, facilitating straightforward alignment with compatible panel cutouts and mating connectors. Its 11-contact configuration supports high-density terminations, while solder cup contacts simplify field termination on common conductor gauges. Ensure panel pattern matches the 11-position layout and the bayonet locking geometry aligns with existing hardware.
This connector operates from -40 °C to 125 °C, covering extreme environmental conditions typical of aerospace and industrial environments. The MIL-DTL-26482 SI qualification provides robust signal integrity under vibration, shock, and EMI exposure. The cadmium-plated aluminium shell further enhances EMI shielding and mechanical robustness, helping maintain performance in harsh duty cycles.
Yes. The 85100AC1811SX50 is designed as a MIL-DTL-26482 SI qualified square flange receptacle with 1/3 bayonet coupling, delivering reliable mating under vibration and dynamic loads. The 11-contact configuration supports complex signaling needs, while the aluminium shell and cadmium finish provide durable, lightweight performance aligned with aerospace connector ecosystems.
Key certifications and compliance include MIL-DTL-26482 SI qualification for military-spec connectivity and REACH environmental compliance. The cadmium plating is a traditional finish used on rugged connectors, but users should verify program-specific material and coating policies. The combination supports regulatory acceptance in aerospace and industrial applications seeking MIL-grade performance and environmental responsibility.
The 85100AC1811SX50 offers durable corrosion resistance, high-density contact configuration, and reliable mating due to the bayonet coupling, all of which reduce maintenance cycles and field downtime. The extended operating temperature range minimizes risk of performance degradation, leading to lower warranty claims and improved uptime for mission-critical equipment, delivering favorable total cost of ownership over lifecycle.
