  • Scanning of all electrically conductive materials (steel or aluminium)
  • With voltage or current output signal
  • With up to 4 galvanically isolated sensors in one enclosure
  • Robust and high quality housing: IP69 pressure-tight and individually tested at 5 bar (for details see technical data)
  • Straight or lateral conductor outlet, available with conductor protection system

Description

Speed sensors of type FA52 are non-contacting multi-channel speed encoders with a stainless-steel flange and sensor tube. They measure frequency in accordance with the eddy-current or difference-hall-effect principle. They acquire the speed of ferromagnetic (FAH type) or electrically conductive (FAW type) gearwheels, 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 different output signals (voltage or current output).
