Latest power connectors combine smaller size with higher performance

RS Components now stocks Molex's Ultra-Fit power connectors, bringing the reliable, easy-mating advantages and space-saving design of the Fit family into wire-to-board applications up to 14A for equipment such as white goods, automotive systems, industrial automation, medical technology, lighting and telecoms. 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, says the company.
