Ultra-Fit Power ConnectorsMolex's Ultra-Fit series eliminates cross-mating issues with the same circuit size, optimizes PCB space, and reduces the chance of loose terminalsPictures of Molex Ultra-Fit™ Power ConnectorsEvery industry faces different power connector challenges. Mis-mated connectors can cause appliances to malfunction. Loose terminals or other possible assembly errors can lead to dangerous vehicle brake failures. The ubiquitous growth of data is causing PCB manufacturers to use more electronics in less board space; compact size and high power density are difficult to reconcile. Molex's Ultra-Fit power connectors address these issues, solving four key design challenges while providing the housing features of the proven Mini-Fit and Micro-Fit 3.0™ connector systems. Shell Features. The housings are color-coded to reduce the risk of mismating. Optional TPA retainer greatly reduces the chance of loose terminals. Streamlined design saves space by being 17% smaller than competitive power connectors, and its ultra-low mating force reduces operator fatigue when mating multiple high-circuit connectors.
1, Molex/Ultra-Fit power connector related characteristics table:
| Features and Benefits: |
| Multiple mechanical key lock styles and color options |
| Multiple connectors are permitted on the same circuit with virtually no possibility of cross-mating. Different colors provide a visual indication of the correct mating of the connectors, which speeds up assembly |
| 17% less pitch than similar power connectors |
| Current density design saves PCB space. Smaller packages can be realized without compromising current-carrying capability |
| Optional Terminal Positioning (TPA) Holder |
| Ensures that the terminals are fully seated in the housing, minimizing the chance of terminals coming loose. Enables terminals to remain in place in the event of failure of the main retention function device |
| Ultra low mating force terminals |
| Reduces operator fatigue and improves assembly quality for high circuit applications |
| Reliable locking housing with anti-hooking design |
| Ensures that the mated connector assembly will not be accidentally disengaged. Mates with a clicking sound when in place. Prevents damage to latch due to wire hooking. |
| Fully isolated terminals |
| Prevents potential damage to headers and socket terminals during handling and mating. |
| Terminal interface with six independent contacts (breakout box terminal design) |
| Provides redundant secondary current paths for long-term performance and reliability |
