GN 50.4 Retaining Magnets Hard Ferrite / Samarium, Cobalt / Neodymium, Iron, Boron, Steel Housing, with Plain Hole

Magnet material: HF - Hard ferrite

Standard Sheet GN 50.4 Print This Page More Information on Retaining Magnets

Product description

Retaining magnets GN 50.4, in combination with the steel housing and the plastic ring, form a system that shields and strengthens the magnet for optimal transmission of the magnetic flux onto the magnetic surface.

To ensure that the magnetic properties are not negatively impaired, the mounting screws should be made of a non-magnetic material, such as stainless steel, brass or plastic.
