Each industry faces different power connector challenges. Failures can occur in appliances as a result of mis-mated connectors. In vehicles, brakes can malfunction from terminal backout caused by harness-supplier assembly errors. 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; an optional TPA retainer significantly reduces terminal backout; a streamlined design up to 20% smaller over similar power connectors provides space savings; and an ultra-low mating force reduces operator fatigue when mating numerous high-circuit connectors.
