Ultra-Fit Power Connectors

Molex Ultra-Fit Power Connectors eliminate same-circuit-size cross-mating and reduce terminal back-out occurrences. The space-saving, low mating force, high-density Ultra-Fit power connector has a 12A or 14A current rating of 3.5mm pitch and is available with color-coding and mechanical keying options. Molex Ultra-Fit Power Connectors offer 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 back out. The streamlined design is 17% smaller than similar power connectors. An ultra-low mating force reduces operator fatigue when mating numerous high-circuit connectors.
