Overview POSIMAG®

POSIMAG® is a non-contact, high resolution magnetic position measuring system for measuring lengths of up to approx. 30 meters. Because of its sturdiness and resistance to dirt, together with the system’s exceptional resistance to wear and tear, POSIMAG® is also suitable for use under challenging environmental conditions.

Advantages at a glance:

  • Non-contact and wear-free
  • Resistant to dirt
  • Shielded metal housing
  • Simple installation and adjustment
  • Standard quadrature encoder interface
  • Protection class up to IP67
  • Measuring ranges up to 30,000 mm

Applications

POSIMAG® position sensors are suitable for linear position measurement in many industrial applications in the production of machinery, plants and precision equipment, in which sturdiness and wear-free design play a crucial role, like e.g. in material handling systems. The POSIROT® product family was developed for similar types of rotary positioning applications.

The functional principle

POSIMAG® consists of a magnetic measuring strip and a non-contact magnetoresistive scanning head. The magnetic measuring strip is periodically magnetized with magnetic north and south poles. To capture a position the magnetoresistive sensor head samples sinusoidal magnetic fields above the magnetic measuring. Standard Resolutions up to 1 µm are available. The signals can be processed by all common industrial control units with suitable signal processing speeds, or displayed directly using a digital display unit from ASM´s PRODIS® series.
