Housing
Steel, zinc plated
Materials of the magnet:
Hard ferrite HF
temperature resistant up to 200 °C
NdFeB ND
Neodymium, iron, boron
temperature resistant up to 80 °C
SmCo SC
Samarium, cobalt
temperature resistant up to 280 °C
Hard ferrite HF
temperature resistant up to 200 °C
Retaining magnets GN 50.4 are a shielded magnetic system.
To ensure that the magnetic properties (adhesive forces) are not impaired, the fixing screws must be made of non-magnetic material (magnetic not conductive).
