Houdermagneet neodymium, schijfvorm

Retaining magnets GN 50.5 are combined with a steel housing and a plastic ring and the plastic cover into a system that shields and strengthens the magnet for optimal transmission of the magnetic flux onto the magnetic surface. For diameter d1 ≥ 50 the adhesive surface is lagged with an all over plastic cover. To ensure that the magnetic properties are not impaired negatively, the fixing screws should be made of non-magnetic material, like for example stainless steel, brass or plastic.
