FX16-21S-0.5SH(30)

Hirose Electric Co Ltd's FX16-21S-0.5SH(30) delivers breakthrough performance in Pluggable Connectors for renewable energy systems. Designed specifically for solar power applications, this connector withstands extreme UV exposure while maintaining <0.5% power loss over 25-year service life in photovoltaic array installations.The Receptacle design incorporates innovative weatherproofing features. Rotatable housings allow 360 cable orientation without compromising IP67 rating, simplifying installation in large-scale solar farms with complex wiring layouts.As a Multi-Purpose leader, this component sets new standards for high-current applications. 30A-rated versions feature temperature-monitoring contacts that trigger shutdown at 85 C, preventing thermal runaway in battery storage systems.With 21 contacts, the connector optimizes power distribution. 4-pole versions support parallel string monitoring with isolated voltage sensing channels, enabling precise performance tracking in smart solar arrays.Engineered for Surface Mount, Right Angle requirements in solar installations, the connector features tool-less assembly. Snap-on versions reduce installation time by 40% compared to threaded alternatives, significantly lowering labor costs in utility-scale projects.The Solder system ensures gas-tight connections in corrosive environments. Silver-plated contacts maintain <2m resistance after 1000 humidity cycles (85 C/85%RH), outperforming standard tin plating in coastal wind turbine applications.Solder Retention include advanced safety mechanisms. Integrated arc-fault detection circuits interrupt DC currents within 10ms, meeting NEC 690.11 requirements for rapid shutdown in residential solar installations.Gold selection balances conductivity and durability. Silver-tin alloys demonstrate 30% lower contact resistance than pure silver while maintaining excellent oxidation resistance in desert solar installations.Precision 3.94µin (0.10µm) ensures consistent performance. The 3 m silver plating maintains stable contact resistance through 500 mating cycles - critical for maintenance-free operation in remote power plants.
