Performance parameters
The gap between the magnet and the iron plate significantly reduces the force needed to detach the magnet from the plate.
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 the countersunk screw head used to attach the magnet. 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 zinc plating. The maximum operating temperature is no more than 110 degrees Celsius. Ferrite magnets stick to metal surface (ferromagnetic materials).
