Magnetic rings for use in harsh environments

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. Unique, multiple or distance coded reference marks are available.

 

Compatible with RLS readheads

Magnetic incremental rings are compatible with RLS standard LM1X family or component level RoLin readheads, which bring reliable operation due to non-contact design. Industry standard incremental or analogue output types are available.  

 

Improved safety and reliability

To assure safety and reliability at high speeds and temperatures the rings can optionally be covered with a protective steel foil. This protective layer also minimises the influence of ageing and possible chemical degradation of the ring’s elastoferrite layer.

 

Easy installation for various shaft diameters

Various diameters are supported for axial rings from 26 mm to 80 mm. 

 

Applications

The magnetic incremental rings bring reliable solutions to tough, hard-working applications including spindles, lathes, other machine tool applications.
