Speed sensors (non-contacting)

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


Speed sensor FAHZ53

  • Due to its design and type approval according to DIN EN 50155 especially suitable for transport technology
  • Speed sensor with two square wave signals, signals 90° offset for direction of rotation detection
  • Robust and high quality housing: IP68 pressure-tight and individually tested at 5 bar (for details see technical data)
  • Excellent vibration and shock resistance
  • Straight connection outlet


Speed sensors of type FAHZ53 are non-contacting 2-channel speed encoders with a stainless-steel flange and sensor tube. They measure frequency in accordance with the difference-hall-effect principle. These speed sensors are suitable for scanning 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.
