Micro-Fit 3.0 Connectors

What Is the Micro-Fit 3.0 Series?

Micro-Fit 3.0 is a high-density power and signal connector series developed by Molex, featuring a 3.0 mm pitch that balances compact size and robust electrical performance.

It is widely used in industrial equipment, robotics, UAV systems, and internal wire harness assemblies, where designers need more power capacity than signal connectors, but smaller size than traditional power connectors.
