FAQs
The 85100A2232SX50 is a square flange receptacle designed for the 851 series with a straight backshell and adaptor option. It ships with a connector and supports a 1/3 bayonet coupling for fast, secure mating. For compatibility, pair with the corresponding Souriau 851 series plug and ensure shell size 22 and solder cup contact arrangements match your harness design.
This receptacle features 32 solder cup contacts in a 32-position layout, with socket (female) contacts loaded for immediate use. The cadmium-plated aluminium shell provides corrosion resistance, and the 1/3 bayonet coupling ensures reliable electrical connection under vibration. The assembly supports high-density signal and power transfer suitable for aerospace and defense applications.
Yes. The 85100A2232SX50 is qualified to MIL-DTL-26482 SI specifications and operates from -40 °C to 125 °C, addressing extreme temperature swings common in aerospace and defense deployments. Cadmium plating adds corrosion resistance, while the aluminium shell keeps weight low, contributing to overall system durability in harsh environments.
Industries such as aerospace, defense, and industrial automation benefit from the high-density 32-position interface, rugged mating, and regulatory compliance. Applications include avionics harnesses, military vehicle wiring, and control systems where reliable, maintenance-friendly interconnects are critical for uptime and mission success.
The combination of MIL-DTL-26482 SI qualification, corrosion-resistant cadmium plating, and a robust 1/3 bayonet mating system reduces field failures and maintenance cycles. Weight savings from the aluminium shell and nearby temperature tolerance contribute to lower lifecycle costs, while the fast mating reduces labor time during assembly and servicing.
