These couplers base on the Fleischmann Profi plug-in coupling 6515 and provide power transmission up to 1 A each contact. They are also vertically self-centering, which effectively prevents unintended uncoupling (e. g. at the transition from horizontal track to a gradient). Uncoupling – even delayed uncoupling – is possible. This allows you to provide an easy power supply system for the entire train. As a result, pick-ups are not required for all coaches. This in turn reduces the load to be drawn by the locomotive. The couplers are equipped completely with 2 connection cables and fit into the standard NEM 362-coupling shaft. The thin cables (0,6 mm) allow a very easy mounting.
