Product details
The HW-28-20-S-D-900-SM-A by Samtec Inc. 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 56 positions, this connector enables complex power conversion architectures. The scalable design maintains safety isolation in high-voltage DC applications.The 0.100" (2.54mm) pitch configuration minimizes partial discharge in photovoltaic systems. This spacing has been optimized for 1500V DC solar array applications.With 2 rows, the connector achieves optimal current distribution for power inverters. The symmetrical layout minimizes thermal hotspots in high-current applications.Featuring 0.100" (2.54mm) row spacing, the design effectively manages creepage and clearance requirements. This critical dimension meets IEC 61730-1 safety standards.The 1.065" (27.051mm) pin length provides secure connections in outdoor environments. The hermetically sealed design has been tested to IP68 waterproof ratings.The 0.165" (4.191mm) mating post length has been optimized for high-voltage applications. This design feature prevents arcing in humid conditions.With 0.900" (22.860mm) stack height, the connector enables flexible power cabinet designs. This dimension has been validated through 1000-hour damp heat testing.Available in Surface Mount 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 30.0µin (0.76µm) 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.
