Electrical connector assemblies typically include a first and second electrical connector having connector housings and a plurality of electrical contacts supported by the connector housings. The first electrical connector is configured to be mounted to a first electrical component so as to place the electrical contacts of the first electrical connector in electrical communication with the first electrical component. The second electrical connector is configured to be mounted to a second electrical component so as to place the electrical contacts of the second electrical connector in electrical communication with the second electrical component, The first and second electrical connectors can be mated to each other so as to place the electrical contacts of the first electrical connector in electrical communication with the electrical contacts of the second electrical connector. Thus, when the first and second electrical connectors are mounted to the first and second electrical components, respectively, and mated to each other, the first and second electrical components are placed in electrical communication with each other. Examples of electrical components to which electrical connectors are configured to be mounted include substrates, such as printed circuit boards, and electrical cables.
