Power Header for High-Current Board-Level Distribution
The Molex 75561-1500 is the 2-position member of the EXTreme PowerMass 75561 series — a through-hole, right-angle header with male blades rated 80 A per position at 450 V. The 2-circuit, 2-row layout with all positions loaded carries bus-level current on each blade, sized for the main DC rail or AC power feed rather than signal lines. Gold plating at 30.0 µin on the mating side supports repeated mating cycles in field-service environments, while the UL94 V-0 black housing meets the flammability requirement for equipment inside an enclosure.
What the Ratings Mean for Your Fit
80 A per circuit means each power blade carries bus-level current — sized for the main DC rail, not a signal line. The 450 V rating gives enough creepage for industrial power distribution without forcing an oversized board footprint. The 30.0 µin gold plating on the mating side is what governs the real duty: it handles repeated connect/disconnect cycles in field-service or test equipment without the fretting corrosion you get with tin. The through-hole, right-angle orientation places the header parallel to the board edge, which suits space-constrained enclosures where the cable exits along the panel wall.
Where It's Used
This is a wire-to-board power interconnect for harness assemblies in industrial cabinets, server PSUs, battery interconnect, and outdoor telecom enclosures. The -40°C to 105°C operating range and UL94 V-0 housing suit environments where the connector sits inside a sealed or ventilated enclosure carrying high current. The board guide feature aids alignment during assembly, reducing shear stress on the solder joints.
