Feature → Business Impact → Application: The 85100AC128SZ50 uses a square flange receptacle with an aluminium shell, eight solder-cup contacts, and a 1/3 bayonet coupling to deliver secure, rugged mating that minimizes field retries and downtime in demanding environments, directly improving installation efficiency on factory floors or aircraft systems. The aluminium shell reduces weight without compromising strength, supporting lighter panel designs in aerospace and industrial automation while maintaining mechanical integrity under vibration. Application-wise, the straight backshell with adaptor and Z orientation simplifies routing and alignment in tight harness geometries, enabling faster harness installation and reduced panel space consumption. This configuration also supports consistent contact performance across the -40 °C to 125 °C range, boosting reliability in temperature-critical applications. Compatibility with Souriau 851 series connectors ensures broader spares commonality and cost-effective maintenance for multi-vendor fleets. Long-tail keywords covered here include MIL-DTL-26482 connectors, Souriau 851 series, 8-contact receptacle, 1/3 bayonet, aluminium shell, square flange receptacle, solder cup contacts, and aerospace-grade connectors. Businesses benefit from improved uptime, standardized components, and reduced procurement complexity in both aerospace and industrial automation contexts.
