List of supported transmission speeds for the 10109 series

The transmission speed that Board to Board Connectors can support varies depending on Mating Height, even for the same series, and the greater the distance, the lower the speed becomes.
For regular products in a series, the "tendencies" of suitability for high-speed transmission are consistent within the series, so the page listing the series shows representative values, and individual combinations are checked separately.
Among them, this series is a special series that offers a variety of options not only for Mating Height but also for mounting height on each board by providing products with several different basic terminal structures.As a result, even within the same series, there are combinations that tend to support different transmission speeds.

Below is a summary of each part and its board mounting details, as well as the compatible transmission speed (defined by our company) and Mating Height when combined.
For combinations of the same Mating Height, those with higher compatible transmission speeds are shaded in light blue.
If there are no restrictions on the mounting height on an individual board, there is a required Pin Counts of poles, and you are considering high-speed transmission applications, we recommend selecting from among these.
