This transfer connector system makes it possible to create plug in transitions on the wiring plane from the internal wiring to the external wiring. This is possible in the wiring pad or on the upper or lower edge area. As well as being able to attach to socket connectors with 0.6 x 0.6 mm and 1 x 1 mm connecting pins have been developed. The particular advantage of these items is their narrow width, which allows them to be assembled in the edge area within the height of the sub rack.
