Information

Stainless steel retaining magnets GN 50.45 are combined with a stainless steel housing and a plastic ring / insulation 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.
