Ferrite pot magnet with counterbore hole D57x15,5x6,2x10,5F
This magnet in housing is circular, cylindrical, shaped like a cylinder or disc.
Holding magnets are simple magnetic circuits composited of a magnet and a steel housing.
The magnet is glued into a steel housing, so it is more protected against impacts. There is a hole in the housing for a flat screw head to be fixed with screws. Due to the casing, the magnet is single-sided. Ferrite magnets are well resistant to corrosion and do not require additional protection. Housing protected by nickel plating. The maximum operating temperature is no more than 110 degrees Celsius.
Ferrite magnets stick to metal surface (ferromagnetic materials).
