What this connector is
The Molex 464369303 is a 3-circuit right-angle power receptacle from the EXTreme Ten60Power 46436 series. It carries female blade sockets rated 60 A per circuit at up to 600 VAC or 250 VDC, terminated via press-fit through-hole — meaning the compliant pins cold-flow into the plated via barrels for a gas-tight joint without wave soldering. The housing is black with UL94 V-0 flammability and carries both board-guide ribs and a mating guide to support automated placement and gross-alignment before the halves seat.
Why the 60 A rating and gold plating matter here
The 60 A per-contact rating is the key figure — it is not a bus-bar carry-current, it is the per-socket limit. All three positions are loaded. The contact finish is 30.0 µin (0.76 µm) gold over the full mating interface, the heavy-contact grade that resists fretting corrosion at high current and supports far more mating cycles than tin-plated alternatives at equivalent current density.
Press-fit termination — what it means for your board
Press-fit termination eliminates the need for wave soldering. The compliant pin section inserts into a PTH barrel and maintains mechanical and electrical contact through spring action against the barrel wall — the joint is gas-tight without solder. This matters most in applications where the connector is on a daughter card that must be back-welded after reflow, or where you want to avoid exposing the connector body to second-pass solder heat. Verify your via plating specification: most press-fit standards require a minimum barrel plating thickness to maintain the gas-tight interface over thermal cycling.
What the EXTreme Ten60Power is used for
EXTreme Ten60Power connectors are industrial power interconnects — the class of board-to-wire or board-to-board connector used to pass high current through an enclosure wall or across a board stack in equipment such as motor drives, power supplies, HVAC controllers, and industrial automation racks. The 5.50 mm pitch and the blade-socket format distinguish it from signal-level pin headers; it is sized for conductor-level current, not logic-level signalling.
