Absolute encoders

Reliable, established and modular

Your Benefits

  • Fewer variants are required since one freely programmable encoder offers all singleturn and multiturn resolutions
  • Easy setup due to various electrical connection adapters (cable, M23)
  • Application flexibility due to easily interchangeable collets for the blind hollow shaft
  • Quick commissioning using the zero set/preset function either at the press of the button on the device or via software
  • Increased productivity due to highly reliable shock and vibration resistance
  • Worldwide availability and service ensure quick and reliable customer service


Reliable, established and modular

The ATM90 with SSI data interface completes the ATM60 product family with through hollow shaft variants. The ATM90 operates reliably even under harsh ambient 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, max. 13 bits, is determined via a mechanical drive with a gearbox that is virtually wear-free. 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 make the ATM90 SSI the perfect match for applications with high mechanical stress and distinct climate fluctuations.
