Remark:
1. MAX.Working Temperature is only for reference,depending on the circuit which the magnet is applications.
2. When L/D ratio of testing piece is eaqual to 0.7,the open flux irreversible loss at Max.Working Temperature less/eaqual 5% is guaranteed.(Lmeans magnetization direction length,D means diameter of magnetic pole surface.)
3. Users are recommended to consult us on any application involving temperature near to 150.
Dimension Range:

Remark:
1. All dimension is in millimeter.
2. Magnets can be machened as per customersrequirements.
