Absolute encoders

Your Benefits

  • Fewer variants are required since one freely programmable encoder supports all singleturn and multiturn resolutions
  • Versatility thanks to a variety of electrical connection adapters (cable, M23)
  • Maintenance-free encoder, long service life
  • Quick commissioning using the zero-set/preset function either at the press of the button on the device or via software
  • Safer applications thanks to highly reliable shock and vibration resistance
  • Worldwide availability and service


The ATM90 PROFIBUS complements the through hollow shaft variants in the ATM60 product family.The ATM90 operates reliably even under harsh environmental conditions. Its rugged mechanical design ensures maximum reliability and a long service life. Magnetic singleturn scanning allows a maximum resolution of up to 13 bits within one revolution. Output and detection of the number of revolutions is determined via a mechanical drive with almost no waste. This means that the ATM90 can be operated without a battery. A shallow installation depth of 60 mm combined with high shock and vibration resistance enable the ATM90 PROFIBUS to be used in applications with high mechanical stress and distinct climate fluctuations
