Ultra-Fit Power Connectors

Each industry faces different power connector challenges. Failures can occur in appliances as a result of mis-mated connectors. Terminal back-out 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. Molex's 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 back-out. 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.

Features and Benefits

• Multiple mechanical keying and color-coded options
• Allow same-circuit, multiple connector use with virtually no chance of cross mating. Color coding provides visual indication of the proper mating connector enabling faster assembly
• 17% reduction in pitch over similar power connectors
• Current-dense design saves PCB space. Allows for smaller packaging without sacrificing current-carrying capabilities
• Optional terminal position assurance (TPA) retainer
• Guarantees the terminal is fully seated in the housing to reduce terminal back-out. Retains terminal if main retention feature fails
• Ultra-low mating force terminal
• Reduces operator fatigue and improves assembly compliance for high-circuit applications
• Positive-lock housing with anti-snag design
• Ensures mated connector assemblies will not accidentally disengage. Provides an audible click while mating. Protects latch from damage due to wire snags
• Fully isolated terminals
• Protect against potential damage of the header and receptacle terminals during handling and mating
• Terminal interface with six independent points of contact (split-box terminal design)
• Offers redundant, secondary current paths for long-term performance and reliability
