Speed sensors (non-contacting)

Non-contacting 2-channel stainless-steel speed sensor, difference-Hall principle


Speed sensor FAHZ5

  • Due to its design and type approval according to DIN EN 50155 especially suitable for transport technology
  • Robust and high quality housing: IP68 pressure-tight and individually tested at 5 bar (for details see technical data)
  • Excellent vibration and shock resistance
  • High degree of EMC immunity for difficult electrical environment
  • Connection outlet straight or lateral; with protective tubing on request
  • Detection of very low speed (near zero speed)


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 speed at the traction motor, gearbox or wheelset. The sensors are available with various output signals:
