Nano-Fit Power Connectors
Molex's Nano-Fit power connectors deliver fully protected header terminals in a small package
Power-application customers are often faced with choosing between headers with exposed terminals that leave connectors susceptible to damage or large, fully isolated headers that consume too much space. Compact Nano-Fit connectors from Molex solve this challenge by providing fully protected header terminals in a small package. Another common issue for design engineers is meeting the requirement to use multiple headers of the same circuit size on one PCB, which complicates assembly and risks mis-mating a receptacle to the wrong header. Nano-Fit connectors address this with multiple mechanical keying options and color-coding logic, reducing cross-mating risk while improving assembly efficiency. Additionally, Nano-Fit connectors offer a 20 AWG UL1569/1007 option, expanding flexibility for power applications.
- Very small, fully-isolated headers deliver up to 69% PCB space savings
- Multiple mechanical keying and color-coded options
- Allows same-circuit, multiple-connector use with virtually no chance of cross-mating
- Color coding provides visual indication of the proper mating connector, enabling faster assembly
- Optional terminal position assurance (TPA) retainer
- Ensures terminals are fully seated in the housing to reduce terminal back-out
- Retains terminals if the main retention feature fails
- Ultra-low mate force terminal reduces operator fatigue and improves assembly compliance for high-circuit applications
- Positive-lock housing with anti-snag design
- Ensures mated connector assemblies will not accidentally disengage
- Provides an audible click while mating and protects the latch from damage due to wire snags
