The encoders contain a contact-less magnetic sensor system and a precision toothed wheel. The sensor’s magnetic field is modulated by the passing of the teeth of the measuring wheel. The resulting sine-cosine voltage is evaluated by the integrated electronic and converted to an incremental output. In addition the encoder can provide a speed dependent analogue output.

  • Heavy industry
  • Paper and packaging machines
  • Bottling plants
  • Transport and storage systems
  • Linear measuring eg. belt-drive 
  • Machines for the processing of steel, wood, rock, textiles and plastics
Advantages of the magnetic system
  • Unaffected by condensation on the measuring wheel and is therefore the preferred choice for applications, where ambient temperatures change or where the relative humidity is high. (e.g. outdoors)
  • Unaffected by oil or dirt penetration.
  • The steel measuring wheel is highly resistant to shock and vibration, unlike glass or plastic graduated discs in other systems.
  • Excellent reliability over a very long life because it does not suffer from the ageing effect common to optical systems.
