HFK mass detection circuits to secure routes and for passive detection of rail vehicles

Vehicle detection

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.

HSK blocking circuits

HANNING & KAHL supplies all track installation components required for operation of blocking circuit systems. The components have proven themselves in years of practical application and are available in numerous versions: insulated tie bars, short circuit connector cables, blocking circuit connector cables, rail boxes, tuning capacitors, input/output junction boxes, connecting cable.
