0.500" (12.70mm) dia x 0.031" (0.80mm) thick with peel-n-stick adhesive backing on South Pole, N40 Rare Earth Neodymium Disc Magnet, Magnetized through the thickness. Nickel Plated. 

Minimum Order Quantity (MOQ) = 10 pcs

These strong neodymium disc magnets with peel and stick adhesive on one side can be used in many applications where the magnetic field is not able to completely hold the magnet in place.  This includes mounting these magnets on non-ferrous surfaces, such as plastic, glass, non-magnetic steel, aluminum or brass.
Disc Magnets can be manufactured with the Director of Magnetization through the thickness or across the diameter. Larger neodymium disc magnets can have multiple poles on the face of the disc magnet, which can significantly increase the holding strength to a ferrous surface.

SM Magnetics, the engineering and manufacturing sister company of SuperMagnetMan, has been assisting Corporate customers for many years with their custom disc magnet applications.  This includes medical magnets and assemblies, sensor magnets, speaker magnets and assemblies, and holding magnets and holding assemblies.
SM Magnetics works with Corporate customers to optimize their design and then manufacture the specific disc magnet or magnetic assembly to meet the required spec.  SM Magnetics has their own ISO certified factories and controls the entire manufacturing process when making individual magnets or entire magnetic sub-assemblies.  For assistance from a technical representative at SM Magnetics, click here for the contact info.
