Product details
EDAC Inc.'s 638-078-331-051 sets new standards for D-Sub Connectors in renewable energy systems. Engineered for photovoltaic applications, this connector maintains <1V voltage drop at 30A continuous current while withstanding 1500V DC isolation requirements.The D-Sub, High Density design features touch-safe housings that meet IEC 62852 safety standards for solar installations.Receptacle, Female Sockets contacts employ silver-nickel alloys that resist sulfidation in harsh outdoor environments.The 78 configuration includes integrated varistors that provide 20kA surge protection per IEC 61643-11.Precision-engineered 4 contact arrangement ensures uniform current distribution across all conductors.Through Hole variant incorporates UV-resistant cable glands that maintain sealing integrity after 10 years outdoor exposure.The 5 (DD, D) High Density architecture provides 75 C temperature rise at full load current in 40 C ambient conditions.Signal implementation uses multi-finger contact design that maintains <5m resistance after 5000 thermal cycles.The Housing/Shell (Unthreaded) system enables tool-less installation with IP68 sealing achieved at 2Nm torque.Our Solder methodology creates gas-tight connections that withstand 1000 thermal cycles from -40 C to +85 C.Steel, Nickel Plated demonstrates >1000-hour salt spray resistance per ISO 9227 with no visible corrosion.The Gold surface treatment maintains <10m contact resistance after 1000 hours damp heat testing.Precision-controlled 15.0µin (0.38µm) ensures proper material migration resistance during extended outdoor exposure.All materials exceed UL94 V-0 requirements while maintaining halogen-free composition.The 3A per Contact design incorporates temperature-compensated contact force that maintains stability across operating range.Shielded include integrated polarity keying that prevents reverse mating in string connections.
