Retaining magnets GN 54.1 are combined with a brass housing, the iron poles and the plastic insulation into a system that shields and considerably strengthens the magnet for optimal transmission of the magnetic flux onto the magnetic surface. This special design is also known by the name “sandwich magnet” or “pole shoe magnet”. The retaining magnets are easy to fasten securely by pressing, shrinking or gluing. k1 is the maximum dimension by which the retaining magnet can be shortened without losing its properties. Mounting these retaining magnets directly in steel components will create a magnetic shortcircuit which reduces the retaining power by as much as 15%. To avoid this, the distance k2 should be maintained between the brass housing and steel part or installation hole. This distance should also be maintained if the retaining magnet is shortened.
