HFK mass detection coils
HFK mass detection coils are specially designed for track installation and HFK mass detection circuits. Different versions are available depending on the application:

  • HFK coil with external tuning module
  • HFK coil with external tuning module, mounted in concrete polymer
  • Mounting kit for installation of HFK coil on sleepers in open track


HFP track circuit transformers
Transmitter and receiver transformers supplied by HANNING & KAHL have proven themselves in HFP track circuits over decades:

  • Symmetric connection cable (installation in the centre of a track in a railbox)
  • Asymmetric connection cable (one-sided installation in a rail box)
  • Symmetric connection cable (installation in the centre of a track without rail box)T

The transformers have protected connections for connecting cable to the controller.
