FAQs
When planning an installation, confirm a 32-contact, socket female solder cup configuration with a straight backshell adaptor and X orientation. The 85100A1832SX50 is a square flange receptacle designed to mate with compatible 851 series hardware and is delivered with connector hardware included. Ensure correct torque, mating alignment, and space for the 41 mm length and 33.7 mm width while accounting for the 18-shell size to prevent binding.
MIL-DTL-26482 SI qualification indicates design and process controls aligned with high-reliability interconnections. This, combined with -40 °C to 125 °C operating temperatures, cadmium plating for corrosion resistance, and an aluminium shell, supports consistent electrical performance and mechanical integrity in vibration, humidity, and thermal cycling common to aerospace and defense environments.
Yes. The 85100A1832SX50 is purpose-built for rugged aerospace and defense use, featuring MIL-DTL-26482 compatibility, 32 contacts for high channel counts, a durable aluminium shell, and a cadmium finish to withstand harsh environments. Its straight backshell adaptor and 1/3 bayonet coupling streamline installation in critical platforms where reliability and maintainability are essential.
To extend service life, perform regular visual inspections for corrosion on the cadmium plating and aluminium shell, confirm mating surfaces remain free of debris, and verify solder cup connections remain mechanically secure. Use proper mating alignment and controlled insertion/removal cycles to minimize wear. Replace any damaged contacts or seals promptly to preserve environmental sealing and electrical integrity.
Upgrading to the 85100A1832SX50 can reduce assembly time due to its ready-to-mate configuration and 1/3 bayonet coupling, lowering field maintenance and downtime. The high-density 32-contact layout enables fewer connectors overall, saving weight and space. With MIL-DTL-26482 SI qualification and REACH compliance, the solution also mitigates regulatory risk and sustains long-term reliability in mission-critical systems.
