FAQs
When installing the 85100A83SX50, plan for a panel cutout compatible with a square flange receptacle, align the 3-contact cavity layout, and secure the adaptor-backed backshell using proper torque on mounting hardware. Ensure the solder cup contacts are clean and seated before mating, and verify 1/3 bayonet engagement for reliable connectivity in automated systems.
Yes. The 85100A83SX50 is designed as part of the Souriau 851 family, featuring a straight adaptor backshell and a 3-contact configuration that aligns with common 851 series mating interfaces. Its aluminium shell and cadmium plating are chosen to sustain mechanical and electrical performance in mission-critical harness assemblies.
The connector operates from -40 °C to 125 °C, with a cadmium-plated aluminium shell that provides robust corrosion resistance. This combination supports stable electrical performance and mechanical integrity in demanding environments typical of aerospace and rugged industrial applications.
MIL-DTL-26482 SI qualification indicates strong MIL-spec compliance for electrical interface integrity. For aerospace programs, it is often paired with system-level requirements (environmental, EMI, and mechanical) and may be supplemented by program-specific certifications. Always verify with your program manager whether additional certifications (such as CE or IP-related ratings) apply to your application.
The 1/3 bayonet coupling enables faster mate/demate cycles, reducing maintenance downtime. Its robust aluminium shell with cadmium plating improves durability against corrosion, lowering replacement frequency. Together with the compact form factor and 3-contact configuration, this connector can lower installation labor costs and improve system uptime in automation projects requiring reliable MIL-spec connectivity.
