Molex's MFB (Futurebus+) connector system is a modular 2.00mm grid system for high-density, board-to-board and cable-to-board applications. MFB is available in 4- and 5-row versions and complies with hard metric packaging standards used in high-density applications such as Futurebus+.

The MFB system offers design flexibility with PCB receptacles and headers that are end-to-end stackable in modular building blocks. The system includes a unique high-pressure press-fit pin design used in both headers and receptacles, along with through hole signal and power modules, an IDT cable receptacle and code keys.
