With innovative new features designed into the already-robust line of Leine Linde rotary encoders, the new M500 encoders are now making their debut. These bearingless inductive encoders promise machine manufactures and owners the best possible life expectancy on the market, increased motion control performance in extreme environments and often in a smaller, lighter size.
M500 rotary encoders are now available in North America through parent company HEIDENHAIN. The new M500 models utilize HEIDENHAIN’s proven inductive scanning technology that makes them immune to contamination and electrical and magnetic fields. The inductive scanning can be used to extend average encoder lifetimes and reduce encoder size while maintaining superior performance and environmental robustness. This new series also offers clever new features to simplify mounting.
One example in this new series of four models is the unique Leine Linde MZI 594 encoder with a sliding shaft design which compensates for thermal influences.

Common applications for these extreme-use encoders include for use in motors, crane automation, pulp and paper processes, and wind energy.
Each of the new M500 series have their own specific features, however, some key ones to note are:
- Operating temperature range from ¬-20 °C...+100 °C (dependent on which version)
- Ingress protection class IP67 (IP69; MZI 594)
- Shaft play (axial) ± 3 mm (MZI 594)
- Rotational speed max 6000 rpm
