Hybrid Power-Signal Plug for Backplane Distribution
The Molex 464379322 is a 17-position plug from the EXTreme Ten60Power 46437 series, carrying a hybrid contact layout of 15 signal pins and 2 power blades. It's built for board-to-board power distribution in backplane or server-PSU assemblies where you need bus-level current and signal lines on one connector body. The 60 A per power contact rating means each blade handles main-rail current — sized for the DC bus, not a signal line. Press-fit termination suits solderless, high-reliability backplane assembly where rework and vibration fatigue are concerns.
The 60 A per circuit on the power blades is the headline number — each power contact carries the full current of a bus bar or power-supply rail. The 15 signal contacts are for control, sense, or low-current lines; they don't share the 60 A rating. The 600 VAC / 250 VDC split matters: the AC rating is higher because DC arcs don't self-extinguish at zero-crossing, so the connector derates for DC bus applications.
How It Compares: 17 vs 32 Positions
The 17-position 464379322 (15 signal + 2 power) sits against the 32-position 464379327 (30 signal + 4 power) at the same 60 A per power contact, same 30.0 µin gold, same press-fit right-angle mounting. The decision is circuit count: the 17-position fits a BOM that needs one power pair and a handful of signal lines; the 32-position doubles both. Board footprint and routing density follow the position count — the 17-position is the smaller, lower-density option for the same power budget per blade.
