Gold-plated brass contacts are another hallmark of M5 and small M6 connector designs. These materials are chosen to improve both conductivity and corrosion resistance. With gold's superior anti-corrosion properties and brass's cost-effectiveness, this combination extends the life cycle of the connectors while maintaining stable and reliable performance across applications. Whether it's ensuring clear signal transmission in 5G components or maintaining uninterrupted power flow in e-bike systems, gold-plated brass contacts create a sturdy, low-resistance pathway that enhances overall system effectiveness.
