Retaining Magnets GN 54.1

Magnet material: ND - NdFeB

Standard Sheet GN 54.1 Print This Page More Information on Retaining Magnets ISO Fundamental Tolerances

Product description

Retaining magnets GN 54.1, in combination with the brass housing, the iron poles, and the plastic insulation, form a system that shields and strengthens the magnet for optimal transmission of the magnetic flux onto the magnetic surface.

This special assembly is also known as a "sandwich magnet".

The retaining magnets can be mounted easily and securely by press-fitting, shrinking or with adhesive.

k₁ is the max. dimension by which the retaining magnet can be shortened without losing its properties.

** Mounting this retaining magnet directly in steel components will create a magnetic short circuit, which reduces the magnetic force by up to 15 %. To avoid this, the distance k₂ between the brass housing and the steel component or installation hole should be maintained. The distance is to be maintained also if the retaining magnet is shortened.
