Absolute encoders

Flexible, smart, compact

Your Benefits

  • Simple, time-saving mechanical installation due to a rotatable connector or rotatable cable outlet, various mounting hole patterns, and many different shafts
  • Simple network installation with various configuration options
  • Intelligent diagnostic functions evaluate maintenance intervals for the entire system, thereby increasing system reliability
  • Customizable Easy setup for various applications allowing binary, non-binary, and non-integer resolutions with the round axis functionality (advanced version)
  • Reliable operation in harsh environments thanks to the rugged, reliable, fully magnetic sensor system
  • Space-efficient and cost-effective design that is suitable for applications where space is tight
  • High performance at a cost-efficient price


Flexible, smart, compact

The AHS/AHM36 CANopen absolute encoder product family provides increased flexibility and diagnostics due to its mechanical adaptation, electrical connectivity, and CANopen communication. With their rotatable connector or cable outlets as well as the various mounting hole patterns and adapter flanges, these encoders are suitable for nearly any application. Individual adjustments can be made to the singleturn/multiturn resolution, the counting direction, and other parameters when integrating the encoders into the CANopen network. The encoder also communicates diagnostic data such as temperature or operating time. Thanks to the large operating temperature range from –40 °C to +85 °C and the protection class up to IP 67, this encoder family can be used in harsh ambient conditions. The rugged, reliable, fully magnetic sensor system provides a maximum resolution of 14 bits for the singleturn variant and 26 bits for the multiturn variant.
