The Molex 465629313 is an 18-position EXTreme Ten60Power receptacle from the 46562 series, combining 15 signal contacts with three power blades in a single press-fit, through-hole housing. This hybrid layout is the series' defining move — it lets a single connector carry both the main DC rail and low-current sense or control lines, saving board space where separate power and signal headers would double the footprint. The power blades are rated 60 A per circuit, which means each one is sized for bus-level current, not a signal line; the signal contacts handle lower duty.
The 60 A per-circuit rating on the power blades is the headline number, but the real load-bearing spec is the contact layout: 15 signal plus 3 power. That tells you the connector is designed for applications where a few high-current paths sit alongside a bundle of lower-current signals — think server PSU outputs, battery management boards, or industrial power distribution where you need to route the main feed and a handful of monitoring lines through one interface. The 600 VAC / 250 VDC voltage rating gives enough creepage headroom for most power architectures, though the DC ceiling is lower; if you are switching DC at high voltage, confirm the clearance against your operating point. The press-fit termination eliminates solder, which makes this a strong candidate for backplane or high-reliability assemblies where rework and thermal stress on the board are concerns.
