Measuring systems for rotative applications

You are here:

These ELGO absolute measuring systems are suitable for rotary applications, e. g. measurement of angles or rotational speeds or as bearingless singleturn absolute encoders. Besides the rotary systems listed on this page, the unguided ELGO absolute encoders for linear applications are  also suitable for angle measurements. 

RMIX2 Incremental Measuring System

RMIX2 Incremental Measuring System Measurement of Lengths, Positions, Angles and Rotational Speed
  • For length- and angle measuring
  • Resolution up to 0.025 mm (at 4-edge triggering)
  • High protection class IP67
  • Distance sensor-tape up to 0.6 mm
  • Standard pole rings: 72 mm, 38 mm und 19.75 mm (diameter)
  • Integration of Hall-Sensor technology and interpolation as single-chip
  • Very robust against dirt

Magnetic rings hard ferrite

Magnetic rings hard ferrite for rotative measurements
  • Interpolation up to zu 22.800 pulses/revolution
  • Direct assembly on axes possible (e.g. motor shaft)
  • Contactless and wear-free measuring principle
  • Applicable in roughest environments (IP67)
  • Vibration and shock resistant

For the use with ELGO incremental sensors EMIX, LMIX, GMIX und RMIX and the battery-powered measuring and indicator systems IZ14, IZ15, IZ16

Pole length 5 mm for GMIX und LMIX sensors
Pole length2 mm for higher resolution EMIX sensors and RMIX sensor
Pole length 2.5 mm for IZ14, IZ15, IZ16

Elastomer-based magnetic-rings 

Elastomer-based magnetic-rings radial and axial versions in different diameters

Magnetic pole rings in conjunction with the appropriate sensor technology are used wherever rotary movements, such as angular positions and speeds on axes and drives, have to be detected, monitored and controlled. The magnetic scanning principle is not only non-contact, wear-free and low-maintenance, it is also extremely robust under extreme environmental conditions. Since the complete system is bearing free, mechanical influences do not directly affect the entire sensor.

  • Incremental or absolute magnetic rings
  • In radial (MRR) or axial (MRA) design
  • Thanks to protection class IP68 predestined for outdoor use
  • Resistant to thermal, chemical and mechanical influences

The incremental rings can be combined with the CMIX, EMIX, LMIX and RMIX series as well as the battery-operated measuring and display systems of the IZ series
