What the 465629304 is and where it sits in the series
The Molex 465629304 is the 4-position single-row member of the EXTreme Ten60Power 46562 series — a power-class blade-and-socket receptacle designed for through-hole press-fit mounting on a PCB power bus. All four circuits are loaded with gold-over-nickel contacts (30.0 µin / 0.76 µm), which is the plating grade you want for repeated mating cycles and lower contact resistance at high current. The connector is black, UL94 V-0 rated, and ships in bulk.
What the ratings mean for your BOM fit
60 A per circuit at 0.217-inch (5.50 mm) pitch is the core decision pair. The current rating tells you this is a board-to-wire power interconnect or a PCB bus-bar blade, not a signal header — at 60 A you are running conductors or bus bars, not PLC logic lines. The 600 VAC / 250 VDC dual voltage rating covers both AC power distribution and DC bus segments common in industrial automation enclosures. The press-fit tails seat directly into plated through-holes without solder, which speeds board assembly and handles the mechanical load of repeated mating better than a pure SMT footprint. Operating temperature is rated –40°C to 105°C. For an enclosed panel with limited airflow this is the relevant ceiling — the contact plating and housing material (UL94 V-0) hold together at full current without the temperature rise triggering a derate concern in most industrial enclosure ambient conditions. The mating guide feature is the blind-mate alignment aid: it drops the matching blade half into the socket housing before the two halves lock, which matters when this connector lives at the back of a densely packed DIN-rail or panel assembly where you cannot see the alignment.
