Feature → Business Impact → Application: The 85100A2027SW50 uses 27 solder cup contacts loaded into a square flange receptacle with a straight backshell. This dense contact arrangement enables higher power and signal density in a compact footprint, reducing harness length and simplifying routing in equipment racks and aircraft panels. In practice, technicians experience quicker, more reliable terminations during assembly and maintenance. Feature → Business Impact → Application: 1/3 Bayonet coupling provides robust mating and rapid field replacement; it resists vibration and misalignment, improving uptime in heavy-duty environments. This makes it well-suited for aircraft, military ground support, and industrial automation where quick, secure connections matter. Feature → Business Impact → Application: Aluminium shell size 20 with cadmium plating delivers corrosion resistance and reduced weight. The result is longer service life, lower maintenance costs, and dependable performance in exterior enclosures, engine bays, and harsh industrial settings. Feature → Business Impact → Application: Operating temperature range from -40 °C to 125 °C and REACH environmental compliance ensure reliable operation across climates. This supports compliance-driven deployments in global facilities and under panel-mounted equipment where temperature swings occur. Feature → Business Impact → Application: Delivered with connector and 27 solder-cup contacts streamline integration into existing Souriau 851-series configurations, reducing on-site configuration steps and accelerating time-to-deploy in new assemblies or retrofits.
