An electrical connector includes a connector frame, a plurality of contacts disposed in the connector frame, a plurality of cables, each of which includes at least one center conductor. The method comprises the step of rotating a surface sensing device, such as a scanning probe, mounted on the scanning head about at least one axis of the scanning head to move the surface sensing device into a plurality of different angular orientations relative to the reference artefact. The force transmitter defining with the bore two fluid chambers. The fabrication process is simple and convenient, and has a short cycle. Each module unit is connected to the connection concerned via a connection facility or connection point.
