RS Components, the trading brand of Electrocomponents plc, has introduced Molex 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 telecom.
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.
