Ultra-Fit™ Power Connectors
Eliminate same-circuit-size cross mating, optimize space savings and ease assembly with low mating force, high-density Ultra-Fit™ Power Connectors
Each industry faces different power connector challenges. Failures can occur in appliances as a result of mis-mated connectors. Terminal backout or other potential assembly errors can lead to dangerous brake malfunctions in vehicles. Pervasive data growth is driving PCB makers to use more electronics in smaller spaces; sourcing small, yet power-dense, electronics is a dilemma. Ultra-Fit™ Power Connectors address these issues, solving four key design challenges while offering the premium housing features of proven Mini-Fit® and Micro-Fit 3.0™ connector systems. Color-coded housings mitigate the risk of mis-mating. Optional TPA retainers significantly reduce terminal backout. A streamlined design that is 17% smaller than competing power connectors provides space savings and an ultra-low mating force reduces operator fatigue when mating numerous high-circuit connectors.
