  • the guide element can have an opening on one side
  • the cable can be inserted or pressed into the guide element laterally through the slot. There is no need to thread the cable through the housing, which may be provided with a plug, since the cable can be pressed into the guide element, regardless of the size of the plug.
  • the guide element can preferably be made of a polymer or an elastomer, e.g. B. a thermoplastic elastomer or rubber exist.
  • a polymer or an elastomer e.g. B. a thermoplastic elastomer or rubber exist.
  • Contamination can penetrate into the housing via the guide element, since the guide element surrounds the cable in a dust-tight or fluid-tight manner, in particular mechanically contacts or clamps the cable jacket.
  • the frame of the cable bushing can have a plurality of guide elements in different sizes for receiving cables with different diameters. Because of the different In the embodiment of the guide elements, cables of different diameters are also enclosed in a fluid-tight manner and guided safely.
