Overview


The Micro-Fit Connector Family offers up to 8.5A with a 3.00mm pitch, delivering power in a compact package in wire-to-wire and wire-to-board configurations. OEMs often need power connectors in space-constrained applications.

Micro-Fit 3.0 Blind-Mate Interface (BMI) Connectors are designed for blind-mating applications. They allow mating misalignment (per product drawing). In hard-to-reach applications, such as drawers or fan assembly trays, connectors need to be mated and unmated without being seen. Doing so can cause damage to the connector and/or terminal and consume valuable labor time.

The Micro-Fit TPA Connector Family helps prevent failure in end products by offering terminal position assurance (TPA). The TPA reduces terminal back-out by providing locking redundancy; assemblers cannot insert the TPA unless terminal is properly inserted.

Micro-Fit 3.0 CPI (Compliant Pin) Connectors provide a compliant pin interface while maintaining all the features of the standard Micro-Fit 3.0 Connector. The robust eye-of-the-needle design provides a reliable interface when recommended board layouts are followed. The Micro-Fit 3.0 CPI Header mates with Micro-Fit 3.0 Receptacle, allowing running changes as boards transition from solder to press-fit applications. For lower applied costs, OEMs often prefer a compliant pin connector over one that requires soldering.

Micro-Fit 3.0 RMF (Reduced Mating Force) Terminals are designed for applications needing lower engagement and disengagement forces or when the units are cycled frequently. The pre-lubricated version can be mated up to 250 times and fit into standard Micro-Fit 3.0 Housings. Applications often require rugged terminals and lower mating force to reduce operator fatigue during assembly and/or to withstand high-mating cycles.
