Applications:

These rings are diametrically magnetized, meaning the magnetization is perpendicular to the axis of the hole. The poles are located on opposite sides of the ring’s circular faces. They are ideal for mounting on a shaft to work with sensors or for electricity generation.

This size is also available axially magnetized as part number R828.
