Whatever your axis design, HEIDENHAIN has the optimal rotary encoder. If the gear shaft passes through the motor shaft, then your best choice is a dual encoder featuring a scanning unit and two rotor units. For more conventional axes, you can achieve high accuracy with a primary encoder on the motor and a secondary encoder on the output end of the axis. In both of these scenarios, HEIDENHAIN offers robust inductive rotary encoder solutions.

Highly integrated dual-encoder
architecture

Advantages over a motor encoder + secondary encoder

  • More compact
  • Single plug and fewer cables
  • Less installation work
  • Automatable installation of disk/hub assembly
  • Lower cost

Modular secondary encoder
architecture

Advantages over a single motor encoder

  • Compensation of gearing inaccuracy
  • High TCP accuracy
  • Detection of gearing wear and failure (predictive maintenance)
  • No multiturn encoder needed at motor
  • Active vibration damping: wider bandwidth and higher rigidity

How rotary encoders meet design and assembly challenges

Robots need to be increasingly fast, precise, compact and cost-effective for a growing range of applications. Rotary encoders play a critical role in robot design and production. They must be matched to the given space, cabling, sensors, precision and tolerances. Installation should be efficient. Find out what to consider.
