PowerWize 3.40mm Interconnects

Molex PowerWize 3.40mm Interconnects leverage Coeur socket technology to deliver power efficiency crucial for cost management. This high-power series features free-hanging and panel-mount housings and right-angle or vertical pin-in-paste reflow SMT-capable headers. Two mechanically keyed color options (black and white/natural) prevent mismating, and the connectors are touch-proof per UL 60950 for safety protection during handling. Molex PowerWize 3.40mm Interconnects offer optimal current-carrying capacity up to 75A with multiple contact beams that ensure low contact resistance, minimal heat generation, and low voltage drop. Positive-locking headers and receptacles provide secure mating and tactile feedback, and the headers support both pin-and-paste SMT reflow and wave solder processing to fit a variety of industrial automation, telecommunications, and networking applications.
