Radial Oriented Ring Magnet Magnets Description

Radial ring magnets are manufactured with the north and south pole on the outside diameter (OD) and inside diameter (ID).
These can be used as motor magnets, sensor magnets .
Radial ring magnets can be manufactured as a single magnet but with limitation on size .Uni-pole magnets are limited to 60 mm on the OD ,12mm on the ID ,and approximately 10mm on the thickness .
Radial rings made in a single piece usually include separate tooling charges for manufacturing and the magnetizing fixtures.
