Product details
The 748665-1 from TE Connectivity AMP Connectors revolutionizes D-Sub, D-Shaped Connectors - Backshells, Hoods technology for renewable energy applications. This robust connectivity solution withstands extreme environmental conditions while maintaining uninterrupted power transmission.As a Hinged Backshell, this product provides complete environmental sealing for outdoor power electronics, achieving IP68 protection even in submerged conditions.Supporting 25 current-carrying positions, the design handles high-voltage DC transmission up to 1,500V for solar farm applications.Engineered for Round cable terminations, the corrosion-resistant contacts maintain low insertion loss (<0.5dB) throughout the product lifecycle.The 180° configuration allows for optimal cable management in wind turbine nacelles, minimizing stress on conductors during yaw movements.The Shielded design provides complete immunity to lightning-induced surges up to 10kA per IEC 61000-4-5, protecting sensitive inverter electronics.Fabricated from Acrylonitrile Butadiene Styrene (ABS), the housing withstands UV exposure exceeding 5,000 hours per ASTM G154 without degradation of mechanical properties.Nickel over Copper contact surfaces ensure stable electrical performance across temperature swings from -40 C to +85 C in desert installations.Including Cable Clamp, the assembly maintains mechanical integrity in vibration environments exceeding 15Hz at 2mm amplitude per IEC 61400-1.The Mating Screws 4-40 implementation allows for tool-less maintenance access, critical for offshore wind farm applications where downtime is costly.The Silver exterior reflects solar radiation to prevent heat buildup while providing high visibility for safety inspections.
