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 radial rings from 30 mm to 406 mm. Radial rings allow heating up to 160 °C, which makes them ideal for shrink fit installation. Due to high precision machining, the rings can also be press-fitted.
Applications
The magnetic incremental rings bring reliable solutions to tough, hard-working applications including spindles, lathes, other machine tool applications.
Please be informed that incremental magnetic rings with DCRM reference mark option are not available for purchase in our online shop so please send your RFQ to sales@rls.si.
For ring speed tables with LM13 encoder please contact sales@rls.si.
