The linear scales usually consist of sintered hard ferrite or hard ferrite particles bonded in plastic or rubber material. Incremental scales feature alternating magnetized north and south poles. Special coding, such as vernier tracks or pseudo random codes, are also possible. Up to 3 tracks can be magnetized on one linear scale.

There are many raw materials that can be used as measurement scales.
We offer linear scales made of

  • sintered hard ferrite
  • Tromaflex® material on a steel substrate

Suitable for absolute or incremental applications, e. g.:

  • Linear encoders
  • Microscope table
  • high-precision length measurement of short distances

General information

The linear scales usually consist of sintered hard ferrite or hard ferrite particles bonded in plastic or rubber material. Incremental scales feature alternating magnetized north and south poles. Special coding, such as vernier tracks or pseudo random codes, are also possible. Up to 3 tracks can be magnetized on one linear scale.

Customized magnetizations and other scale geometries are, of course, possible. Please feel free to contact us about this.

Sintered hard ferrite scales

The linear measurement scales are defined by a high level of remanence and accuracy. However, due to the hardness of the sintered material, the scales are highly fragile when subjected to impacts and are therefore the right choice for high-precision applications.
