Uses for our rare earth ring magnets

Ring magnets are one of the most popular shapes of a magnet for manufacturing applications. The hole allows for the rare earth ring to be slotted on a protruding element such as a rod. Likewise, the round outer diameter can fit snugly inside a tube to create a piston-like arrangement. Mechanical elements in manufacturing often rely on magnets to ensure moving parts engage and disengage in the correct positions. Complex machinery relies on precision if stray mechanical apparatus is allowed to vary from their intended path the results can be debilitating.

Neodymium rings are also the most common form of magnet to be found in sensors such as security gates, alarm systems and security doors. Permanent magnets provide a powerful holding power that is not reliant on electricity or any other external power source. This makes them an ideal choice for these types of systems as they need to withstand the potential for a failure of the power source and attempt to circumnavigate a security system.
