The SAMTEC DWM series micro board stacker connectors are engineered for demanding high-density applications requiring robust board stacking solutions. These connectors utilize LCP (Liquid Crystal Polymer) for the insulator material, providing excellent electrical and mechanical properties. The terminal material is phosphor bronze, plated with either gold or tin over nickel to ensure reliable signal transmission and corrosion resistance. The DWM series is suitable for 'skyscraper' board stacking, offering both surface mount and through-hole options to accommodate various manufacturing processes. For optimal mechanical stability, Samtec recommends using mechanical board spacers, particularly in applications with gold-plated connectors. This series is non-standard and non-returnable.
