Power connectors fit to last a long time

The new 3.5mm-pitch Ultra-Fit connectors join the Fit portfolio alongside the Mega-Fit 5.7mm-pitch series rated up to 23A per circuit, the 4.2mm/13A Mini-Fit, and the 3mm/5A Micro-Fit. Featuring the Fit-family split-box terminal design with six points of contact, Ultra-Fit connectors have low insertion force allowing fast, fatigue-free productivity, and deliver long-term reliability in the field.

With multiple features to ensure correct mating, and terminal position assurance (TPA) to prevent back-out, they have a 17% smaller footprint than competing, similarly-rated connectors.

Multiple mechanical keying options allow several sets of connectors to be used in the same assembly without fear of cross insertion. There are also colour-coding options that provide clear guidance for assembly during production or maintenance in the field.

The positive-lock housing confirms mating with an audible click and prevents accidental disengagement. In addition, anti-snag design prevents wires becoming trapped and damaging the latch.

All header and receptacle terminals are fully isolated. In conjunction with the scoop-proof housing, this prevents damage during handling and mating. In addition to preventing terminal back-out by ensuring the terminal is fully seated in the housing, the TPA built into the new Ultra-Fit series and other Fit-family connectors also provides secondary protection against failure of the connector’s main retention mechanism.
