Absolute rotary magnetically coded position measurement systems

Highly precise positional feedback

Regardless of whether they are highly integrated in the motor or on large diameters, the BML absolute position measurement systems from Balluff provide absolute position feedback – in every position, immediately and without a reference run.

BML absolute engine-feedback system

BML absolute motor feedback systems are highly precise, extremely compact and easy to integrate in motors.

Applications

  • Rotary electric drives and motors
  • Robotics
  • Feedback systems for mounted rotary encoders
  • Machine tools
  • Rotary indexing tables
  • Position feedback for rotary and swivel drives, and much more

Benefits

  • Highly precise and accurate: Saves energy as a result
  • Long-term-stable measurement body with Permagnet® technology: For high installation availability
  • Robust metal design for sensor technology and measurement body: Long service life and low overall installation costs
  • High integration capability: Saves space as a result
  • Simple, fast installation using the calibration software
