The Micro-Fit Series of wire-to-board/wire-to-wire connectors from Molex|Molex Connectors is a: The Micro-Fit connector system provides a housing feature that prevents mismating, reduces terminal rollback, and reduces operator fatigue during the assembly process. The Micro-Fit connector family can withstand operating temperatures up to 125°C and is available in a variety of circuit sizes and cable lengths for power supply applications, as well as board-to-board, wire-to-board, and wire-to-wire configurations.The Micro-Fit connector family offers higher currents up to 8.5A and a thickness of 3mm, delivering power in compact packages and in wire-to-wire and wire-to-board configurations.OEMs need power connectors for space-constrained applications.Micro-Fit 3.5A and 3mm connectors are also available for power supply applications. Micro-Fit 3.0 Blind Mating Interface (BMI) connectors are designed for blind mating applications. These connectors allow for mating mismatches (per product drawings). In hard-to-reach applications, such as drawers or fan assembly trays, the connectors require a hidden mating design that can result in damage to the connector and/or terminals and consume valuable man-hours.
