Control Cables

If a movement is to be transferred from A to B, this can be done electrically, hydraulically or mechanically. Cost-effective and infallible is always the mechanical cable, since the installation requires no special knowledge or tools, such as test equipment, etc.

Mechanical components e.g. Linkage, however, are rigid and therefore can’t overcome curves and corners, in such cases, push / pull cables – also called Bowden cables – are used.

Control cables essentially consist of a permanently installed, flexible conduit and a moving inner wire running in this conduit. If the inner wire is now displaced at one end of the conduit “A”, this wire also moves at the other end of the conduit “B”, and thus the movement is transferred from point A to point B.

Controls cables are particularly common in land, water and air vehicles. Typical applications are throttle cables, brake cables, but also actuations of valves, doors, hoods and covers. Also in building industry there are application areas, e.g. in the operation of skylights windows.

The challenge is to design the optimum transmission cable for the particular application.

The following specifications / criteria must be observed:

  • intended use (eg throttle cable, brake cable, transmission cable)
  • Cable lengths of more than 10m are possible
  • Maximum load for compressive load: 2,500N
  • Maximum load for tensile load: 15.000N (brake cable)
  • Temperature range from -40 ° C to over 150 ° C
  • Maximum stroke up to 300mm
  • Minimum bending radius 50mm
  • Extremely low friction values possible by using Teflon coated components
  • Water resistance up to IP67
  • Corrosion resistance by agreement
  • Resistance to chemicals by agreement
  • Many colors selectable
  • End connections to other components by arrangement
