GN 50.4 Retaining Magnets Steel, Disk-Shaped, with Tapped Hole


GN 50.4 Steel Retaining Magnets, Disk-Shaped, with Tapped Hole Magnet material: HF - Hard ferrite

Product description


GN 50.4 retaining magnets, 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.
