Rotary Encode Magnet / Sensor Magnets（Encoder /Multipole Magnets）
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.
HSMAG Magnet Co.,Ltd can provide the customized size encode magnets according to client specific requirement .
