The robust RLS magnetic rings consist of a vulcanised elastoferrite layer securely attached to a steel hub. The elastoferrite layer is magnetised with 2 mm or 5 mm long alternating magnetic poles which form an incremental magnetic pattern.

Additionally, reference mark magnetic signature can be added to incremental magnetic pattern.


  • Axial rings
  • Excellent dirt immunity
  • Bi-directional reference mark
  • High reliability from proven noncontact sensing technology
  • Industry standard digital outputs
