Product details
TE Connectivity AMP Connectors's 748482-5 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 44 configuration includes integrated varistors that provide 20kA surge protection per IEC 61643-11.Precision-engineered 3 contact arrangement ensures uniform current distribution across all conductors.Through Hole, Right Angle variant incorporates UV-resistant cable glands that maintain sealing integrity after 10 years outdoor exposure.The 3 (DB, B) 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 (4-40) 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 30.0µin (0.76µm) ensures proper material migration resistance during extended outdoor exposure.All materials exceed UL94 V-0 requirements while maintaining halogen-free composition.The 2A design incorporates temperature-compensated contact force that maintains stability across operating range.Board Lock include integrated polarity keying that prevents reverse mating in string connections.
