HOME > MAGNETIZER> Super multi-pole magnetizer
This equipment was developed for magnetization of magnetic encoders (rotary and linear types) and is capable of a magnetization pitch as from 0.1 mm up to several mm.
Accuracy of magnetization pitch is much better than that of the yoke.
Capable of magnetizing rare-earth magnets for specific specifications
Capable of magnetizing long magnets longer than 5m
