New inductive encoders for challenging machine environments from Leine Linde

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 bearing-less inductive encoders promise machine manufactures and owners high life expectancy, as well as increased motion control performance in extreme environments and often in a smaller, lighter size.

Several variants of these M500 rotary encoders are now becoming available in North America through parent company HEIDENHAIN. The new M500 models use HEIDENHAIN’s proven inductive scanning technology that makes them immune to contamination and electrical and magnetic fields. The inductive scanning also can be used to extend average encoder lifetimes, as well as 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 in motors, crane automation, pulp and paper processing, and wind energy.

Each of the new M500 series encoders have their own specific features. Some key ones to note include:

  • Operating temperature range from –20 °C to 100 °C (dependent on which version)
  • Ingress protection class IP67 (IP69; MZI 594)
  • Shaft play (axial) ± 3 mm (MZI 594)
  • Rotational speed max 6,000 rpm
