Han® 4B Standard Rectangular Power Connectors

HARTING Han^® 4B Standard Rectangular Power Connectors deliver high power density while reducing installation space requirements by up to 40%. The Han 4B housing size covers applications for which Han 6B is too large, and Han 3A cannot meet the power requirements. The HARTING Han 4B connectors provide a compact, cost-effective solution for space-constrained applications. These connectors support up to two modules or four modular Dominos, maintaining compatibility with existing Han-Modular^® inserts and accessories.
