Fit Family Connectors

Molex Fit Dual-Row Connectors provide a scalable power connectivity platform for wire-to-wire, wire-to-board, and board-to-board applications. Spanning Nano-Fit™, Micro-Fit™, Ultra-Fit™, Mini-Fit™, and Mega-Fit™ connector systems, these Molex series address a range of design challenges, from space-constrained devices to power-intensive equipment. Built-in features such as polarization, color coding, and keying help improve assembly efficiency and reduce the risk of mis-mating, while an optimized balance of connector size, current capacity, and reliability enables consistent performance across diverse applications.
