What it is and where it sits in the series
The Molex 464369313 is the 18-circuit right-angle member of the EXTreme Ten60Power 46436 series — a mixed-signal-and-power rectangular connector built around a 60 A per-circuit rating at up to 600VAC or 250VDC. The contact layout runs 15 signal pins plus 3 dedicated power pins, all gold-plated at 30.0 µin (0.76 µm) on the mating interface and loaded in every position. Press-fit tails mean it lands on the PCB without solder — the through-hole press-fit interface is sized for the bus-bar current path rather than hand-solder reflow, and the right-angle orientation routes current at the board edge into the power distribution plane. Board guide and mating guide features are molded into the housing to align the mated half during engagement and keep the pair seated under industrial vibration — the black housing carries a UL94 V-0 flammability rating, which sets the material grade for enclosed cabinet deployment.
What the ratings mean for your selection
The 60 A per-circuit rating applies individually to each contact — so the three dedicated power pins each carry 60 A independently while the 15 signal positions handle control-level current. The 600VAC rating covers the AC bus side; the 250VDC companion rating handles the DC rail. Confirm your distribution voltage sits inside both limits before committing — a 400VAC system uses the AC rating; a 320VDC bus uses the DC rating. Gold at 30.0 µin (0.76 µm) is a mid-grade flash — above a basic tin or thin gold, which means it tolerates dozens of reconnections without the contact resistance degradation that tin contacts see after a few mates. For a power bus that gets serviced or reconfigured, that plating thickness is the difference between a field repair that holds and one that doesn't. The -40°C to 105°C operating window covers refrigerated enclosures and heated cabinet environments; the press-fit interface transfers heat to the PCB plane, so the derating curve on the product drawing governs how many of the three power circuits you can run at full 60 A simultaneously in a closed cabinet at the high end of the temperature range.
Mating and termination
This is the female receptacle (blade-and-socket) half — it mates with the matching EXTreme Ten60Power plug or header in the same series. The board guide and mating guide features control alignment during engagement, which matters for the press-fit tail seating in the plated through-holes on the PCB. Press-fit termination requires a controlled hole size in the PCB — the product drawing specifies the press-fit zone dimensions. The right-angle orientation places the mating face perpendicular to the board plane, so the plug half approaches from the board edge, not overhead.
