Ultra-Fit™ Power Connectors

Molex Ultra-Fit™ Power Connectors eliminate same-circuit-size cross mating and reduce terminal backout occurrences. The space saving, low mating force, high density Ultra-Fit power connector has a 12A or 14A current rating, 3.5mm pitch, and is available with color coding and mechanical keying options. Molex Ultra-Fit Power Connectors offering the premium housing features of proven Mini-Fit® and Micro-Fit 3.0™ connector systems. Color-coded housings mitigate the risk of mismating. An optional TPA retainer significantly reduces terminal backout. The streamlined design is 17% smaller than similar power connectors. An ultra-low mating force reduces operator fatigue when mating numerous high-circuit connectors.
