Magnetic encoders

Highly precise, robust and rapid-working encoders

High-precision fast measuring systems with magnetic encoders enable precise positioning in extremely dynamic applications.

Their robust construction allows their use in extreme environments.

The most important benefits

  • Contact-free and therefore wear-free
  • Incremental or absolute interfaces
  • High resolution to 1µm
  • Measurement lengths of up to 48 m
  • Flexible installation
  • Long service life

Product families

Absolute magnetic encoder (for linear applications)

Dynamic and precise positioning with high repeatability
