Slip Rings TKA series

  • sealed design with the ability to change of circuit number
  • versions with build-in rotation transducer for the rated capacity limiter systems and protection systems
  • desing with the central hole (opening) for the cable of accelerator pedal, hydraulic hose and etc.
  • optional carrier for the turning a slip ring

The slip rings TKA series (rotating contact devices) are designed for transferring power or data signals from the stationary mechanism to the revolving mechanism.

The most often used as a mobile crane of the slip rings (RCD) for connection of the electrical signals installation turning of crane with the electric equipment of the based chassis.

The slip rings can be completed the build-in rotation transducer with digital or analog interface with the discrete input.

We can to do individual offer the slip rings TKA series with the increased operation voltage.
