GN 50.4 Retaining Magnets Disk-Shaped, with Bore

Material: HF - Hard ferrite

Standard sheet GN 50.4 Print this page More Information on Retaining Magnets

Product description

Retaining magnets GN 50.4 are combined with a steel housing and a plastic ring into a system that shields and strengthens the magnet for optimal transmission of the magnetic flux onto the magnetic surface.

To avoid negatively impacting the magnetic properties, the fastening screws should be made of a non-magnetic material such as stainless steel, brass or plastic.
