Hybrid Power-Signal Plug for Backplane and Busbar Duty
The Molex EXTreme Ten60Power 464379321 is a 16-position right-angle plug (15 signal contacts + 2 power blades) from the 46437 series, rated 60 A per circuit with gold 30.0 µin (0.76 µm) plating on the mating surfaces. The press-fit termination suits solderless backplane assembly — the compliant pin presses into a plated through-hole without thermal stress, making rework straightforward. The black UL94 V-0 housing carries board guides and a guide pin for alignment during mating, typical for high-current power distribution in server PSUs, industrial busbars, and battery interconnect systems.
What the 60 A Rating Means for the Board Layout
60 A per circuit on the power blades means each blade carries bus-level current — sized for a main DC rail, not a signal line. The 600 VAC / 250 VDC rating covers both three-phase industrial bus voltages and battery or DC-link circuits. Gold plating at 30.0 µin (0.76 µm) supports repeated mating cycles in field-service or modular power-distribution racks — well above the 15 µin typical for signal-only connectors.
16 vs 32 Positions — 464379321 vs 464379327
The 32-position sibling 464379327 (30 signal + 4 power) shares the same series, 60 A rating, gold 30.0 µin plating, press-fit termination, and right-angle orientation. The decision between 16 and 32 positions is purely about circuit count — the footprint class, board keep-out, and mating receptacle family are identical. If the BOM calls for 16 circuits, 464379321 is the direct fit; if more power or signal channels are needed, 464379327 doubles the count without changing the connector architecture.
