What it is and where it sits in the series
The Molex 465629321 is the 16-position member of the EXTreme Ten60Power 46562 series — a high-current board-level power receptacle built around a mixed signal-plus-power contact layout. The 15 signal and 2 power positions are distributed across the full 16-way footprint, so the 60A current rating applies to the power positions specifically; the signal circuits carry the standard signal-level duty within the same housing. Gold plating at 30µin (0.76µm) covers the mating interface across all positions, giving the connector the durability for repeated mating cycles in equipment that sees field service or panel-level rework.
Voltage and current — what the ratings mean for the application
The 600VAC / 250VDC dual voltage rating reflects the connector's suitability for AC mains distribution and DC bus architecture within the same board stack. The 60A rating is the per-circuit ceiling at the power positions — the signal circuits in the same housing operate at standard signal current levels, so mixing them in one connector does not de-rate the power pins. UL94 V-0 housing material means the connector body survives the temperature and flame exposure of a typical industrial enclosure without additional shielding.
Termination and mounting — press-fit for solder-free board assembly
Press-fit through-hole termination lets the connector land in the PCB without reflow — the compliant pins gasless-fit the plated-through hole and carry the full 60A current path through the board interface. The through-hole form factor suits high-current bus bars and backplane cards where wave-soldered headers would see thermal stress. The black housing and the mating guide feature (a locating keying feature on the housing) support blind-mate insertion in dense equipment racks, keeping the 16-way alignment controlled during assembly or field replacement.
