Molex Ultra-Fit Power Connectors 3.50mm Contact Pitch
The Ultra-Fit Tangleless (Anti-Tangle) Connector is a family of wire-to-board connectors with a 3.50 mm contact pitch and a current rating of 14.0 Amps. In order to achieve flexible application and efficient assembly, various excellent design versions are available for users to choose from.
Advantages
Variety of anti-mismating mechanisms and color coding options
- When mating multiple connectors of the same way count, cross mismating is almost impossible. Assemblers can refer to color coding to ensure correct mating to speed up the assembly process
17% reduction in terminal pitch compared to similar power connectors
- The connector features a current-dense design that saves board space. Although the package size is smaller, it does not affect the current carrying capacity
Positive locking housing with anti-snag design
- Mated connector assemblies cannot be unintentionally unmated. Click when mated. Protects latches from wire snagging
Complete isolation between terminals
- Protects base and receptacle terminals from damage during handling and mating
There are 6 independent electrical contact points on the terminal interface (the terminal square head adopts a bifurcated design)
- Provides redundant current paths for long-term reliable connections
