Application of rotary encode magnet

Application : magnet for  rotary  encode 

Encode magnetic rings  is a type of plastic ferrite magnet. The plastic ferrite magnet will be  magnetised with  1 mm , 2 mm,3mm pole pitch which form an incremental magnetic pattern.

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


Super Magnet Co.,Ltd  can provide the customized size encode magnets  according to client specific requirement .
