What it is — and where it sits in the EXTreme Guardian line
The Molex 2141140001 is the 38-position, 5-row vertical receptacle member of the EXTreme Guardian 214114 series, housing female blade sockets rated 80 A per circuit at 125 V. The push-pull fastening type and a mating guide are built into the housing for repeatable alignment in high-current busbar interconnects — the class of connector that feeds power rails across industrial automation racks and motor-drive harnesses where the full load current runs through the blade interface, not just signalling.
What the ratings mean for the fit
The 80 A per circuit rating at 125 V is the primary selection gate — a 5-row layout across 38 positions distributes that current across multiple parallel blades, which is the design intent of this series. What ambient that 80 A is stated at is not printed in the spec table; the operating window runs to 105 °C, so the real usable current in a warm cabinet will derate below the headline figure — every amp makes heat in a dense power bus. The gold plating at 30 µin (0.76 µm) over copper alloy is a mid-grade contact finish that supports repeated push-pull cycles without the fretting vulnerability of pure tin, and the LCP insulator body holds its geometry at the upper temperature limit without the softening risk of a lower-grade polymer. The 125 V rating classifies this as a low-voltage power-distribution interconnect — not a PLC backplane or instrumentation bus connector. Through-hole solder termination requires wave or hand-solder access to the solder side.
