Rail Speed Sensors

 Rail speed sensors

  • Non-contacting and wear-free measurement
  • Measurement of very low and very high speeds
  • Obtaining outputs compatible with computers and high-level systems
  • Stable signal due to an integrated amplifier
  • Meets EN50155 (FA52 sensor type)


  • For older vehicles
  • Traction motors
  • Wheelsets
  • Gearboxes
  • Recognition of rotation direction
  • Traction motors
  • Acquire speed from screw heads, drill holes, aperture grooves or pulse heads

Speed sensors of type FA5 are non-contacting 2-channel speed encoders with a stainless-steel sensor tube. They measure frequency in accordance with the difference-hall effect principle. They acquire the speed of ferromagnetic materials, e.g. gearwheels with various tooth shapes, screw heads, drill holes, apertures, grooves or pulse bands on smooth shafts (accessories). Their compact and robust design, as well as the relevant tests as per DIN EN 50155, make them ideal for applications in the field of transport technology, e.g. measuring the speed at the traction motor, gearbox or wheelset. The sensors are available with various output signals

Scanned objects (Examples)

  • Toothed gear wheels (metal)
  • Perforated discs
  • Holes, grooves
  • Toothed belt for installation on shafts
