  • Incremental encoders are used in applications where instant and accurate relative position is needed, in either analogue or digital format.
  • Absolute encoders are used in applications that need a high speed unique digital output for each position and offer functional immunity from power interruptions.
  • Linear scales are used where straight-line position information is needed - usually X, Y or Z axes.
  • Rotary scales are used for angular position information and the motion control of rotating elements.
  • Ultra-High Vacuum (UHV) encoders are optimised for use in vacuum environments.
  • Functionally safe (FS) encoders are certified to SIL2 PLd for functional safety applications.
  • Extended Temperature Range (ETR) encoders are able to operate in environments with extreme high and low temperatures.
