Product details
The 951421-9012506-AR by 3M represents a quantum leap in Rectangular Connectors - Board Spacers, Stackers (Board to Board) for renewable energy systems. This high-voltage interconnect solution combines exceptional insulation properties with robust environmental resistance for solar and wind power applications.Supporting 21 positions, this connector enables complex power conversion architectures. The scalable design maintains safety isolation in high-voltage DC applications.The 0.079" (2.00mm) pitch configuration minimizes partial discharge in photovoltaic systems. This spacing has been optimized for 1500V DC solar array applications.With 1 rows, the connector achieves optimal current distribution for power inverters. The symmetrical layout minimizes thermal hotspots in high-current applications.The 0.835" (21.200mm) pin length provides secure connections in outdoor environments. The hermetically sealed design has been tested to IP68 waterproof ratings.The 0.157" (4.000mm) mating post length has been optimized for high-voltage applications. This design feature prevents arcing in humid conditions.With 0.567" (14.400mm) stack height, the connector enables flexible power cabinet designs. This dimension has been validated through 1000-hour damp heat testing.The 0.110" (2.800mm) tail length has been optimized for power electronics assembly. This dimension ensures reliable connections in high-current busbar applications.Available in Through Hole configurations, the connector supports renewable energy installations. The screw terminal version facilitates field maintenance in solar farms.The Solder termination method has been engineered for high-voltage reliability. The compression-style contacts maintain stable resistance under thermal cycling.Utilizing Gold plating technology, the contacts deliver exceptional performance in corrosive environments. The silver-based finish maintains conductivity in coastal installations.The Flash plating thickness provides optimal current-carrying capacity. This specification has been validated through 1000-hour salt spray testing.The Black housing material features UV-resistant properties for outdoor use. The halogen-free compound maintains mechanical properties in extreme weather conditions.
