What this is
The Molex 465629316 is the 31-position press-fit receptacle in the EXTreme Ten60Power 46562 series — a hybrid power and signal connector built around a single high-current power circuit alongside 30 signal contacts. The 60A current rating applies per circuit, making this a board-stack power-delivery node rather than a standard signal header.
Ratings and what they mean
The 600VAC / 250VDC dual-voltage rating covers both AC mains-adjacent and DC bus rails — a key distinction for industrial power architectures where the same connector may land on a 48V DC bus or a rectified AC rail. The 60A per contact rating is sized for the power blade, and the 30 signal contacts handle control and sense paths at the same interface, which eliminates a separate signal connector in dense power-control boards. Gold plating at 30.0µin (0.76µm) is the heavy-gold grade in this series — the thicker deposit resists fretting on the power blade under vibration and extends mating cycle life compared to tin. For applications where the assembly sees field service or repeated mate/de-mate, the plating grade matters as much as the current rating. Press-fit termination bonds the receptacle directly into the PCB plated-through hole without solder — the interference fit carries both current and mechanical retention. This is the right choice when the connector must survive high current without a solder joint thermal bottleneck, and when the board will see thermal cycling that would fatigue a pure solder joint. UL94 V-0 flammability rating on the housing means the connector body self-extinguishes and does not drip burning particles — a baseline requirement for industrial enclosures and any end product targeting UL certification.
Sourcing and lifecycle
The 31-position count and the 30 signal + 1 power layout are specific to this variant — confirm the signal-to-power split matches the board's power architecture before committing, because the series offers alternatives with different power-circuit counts that would change the pinout mapping on the power rail.
