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 and flexible electrical installation with various configuration options and adjustable SSI protocol structure (programmable SSI version)
  • Easy setup for various applications allowing binary, non-binary, and non-integer resolutions with the round axis functionality (programmable SSI 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 SSI absolute encoder product family provides increased flexibility due to its mechanical adaptation, electrical connectivity, and SSI 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. The AHS/AHM36 SSI encoders are able to connect to a wide range of controls due to a programming tool that can be used to make individual adjustments to the structure of the SSI protocol, in addition to adjusting the singleturn/multiturn resolution, the counting direction, and other parameters. Thanks to the large operating temperature range from –40 °C to +100 °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.

At a glance
  • Compact 36 mm absolute encoder with max. 26 bits (singleturn: 14 bits, multiturn: 12 bits)
  • Face mount flange, servo flange, blind hollow shaft
  • Rotatable M12 connector or rotatable cable outlet
  • SSI interface
  • Programmable SSI version: Resolution, preset value, etc. can be programmed (depending on the type)
  • Protection class up to IP 67 (depending on the type)
  • Operating temperature: –40 °C to +100 °C (depending on the type)
