What it is
The Molex 0464379307 is the 7-position member of the EXTreme Ten60Power 46437 series — a right-angle male blade plug rated 60 A per circuit at 0.217-inch (5.50 mm) pitch, terminated press-fit into the PCB through-hole. All seven positions are loaded with gold-plated contacts (30 µin / 0.76 µm finish thickness) and the housing carries a board guide plus a guide pin to take the alignment load off the power blades during mating.
Key ratings and what they mean
60 A per circuit is the headline figure, but the 30 µin gold on the mating contact is what makes it stick — gold plating above the tin-underlayer governs both the contact resistance at first mate and the cycle life of a reconnectable high-current joint. For a connector specified at this current level, the plating grade is the decision parameter, not the headline amp number. The 0.217-inch pitch is the Ten60Power standard bus bar spacing — it defines the board footprint and the routing channel between adjacent circuits. At 7 positions in a single row, the right-angle orientation makes this a board-edge power distribution node, not a mid-board daughter card connector. 600 VAC / 250 VDC covers the AC mains and DC bus rails common in industrial equipment. The −40°C to 105°C operating window is wide enough for both outdoor cabinet and factory-floor environments; the UL94 V-0 housing rating is the relevant flammability class for enclosed equipment panels.
Press-fit termination
Press-fit tails eliminate a solder reflow step and carry more current than a solder pad before thermal fatigue sets in — a meaningful advantage for a 60 A connector that will see load cycling. The through-hole press-fit format also gives the connector mechanical standoff from the board surface, which matters for right-angle connectors where the board edge is the mounting reference. The guide pin and board guide feature together mean this connector is designed to be piloted into the receptacle with the alignment already taken — critical for a high-current blade where any angular or lateral offset at engagement loads the contacts unevenly.
Where this class is used
EXTreme Ten60Power is a board-to-board and board-to-bus power interconnect family — the 60 A per circuit rating puts it in power distribution roles inside industrial automation cabinets, UPS systems, and motor drives where the PCB itself carries the high-current bus rather than a discrete cable harness.
