Material: Sintered NdFeB, Grade N38UH

Please note that all neodymium rare earth magnets are fragile and require caution when installing to prevent shattering the magnet due to their brittle nature, and to avoid injury due to pinching.

Neodymium magnets are perfect for use in dry indoor areas. Diametrically magnetised magnets are often utilised in sensor technology or for magnetic couplings or switches.
