Connectors combine small size & large current density

The Nano-Fit power connector, which has a 2.50mm pitch and is rated for up to 4.0A, is claimed to provide up to 69% PCB space savings, making it the smallest comparable fully-isolated header in the market. Compared to similar power connectors, the Ultra-Fit connector is 20% smaller, with a 3.50mm pitch and 12.0A power rating.

Both the Nano-Fit and Ultra-Fit power connectors are offered with the same housing features as the Micro-Fit, Mini-Fit and Mega-Fit connector systems. These features include positive locking polarised housings with fully isolated headers, which ensure that mated connector assemblies will not accidentally disengage, and protect the terminals from potential damage during handling and mating. The risk of mis-mating is reduced by colour-coded and mechanical-keyed housings, while terminal backout is reduced by an optional terminal position assurance. When mating numerous high-circuit connectors, the ultra-low mating force eases assembly and minimises operator fatigue.

“Each industry faces different power connector challenges; whether these are same circuit size cross-mating, terminal backout cause by assembly errors or limited PCB space,” commented Corey Schroeder, Global Product Manager, Molex. “Molex solves these issues with the Nano-Fit and Ultra-Fit power connectors, which feature an optimum combination of current density, tight pitch and row spacing to enable delivery of more power per linear and square millimetre than other competitive power products in the industry.”
