Performance parameters
The pull force given refers to hoisting capacity measured in optimal conditions, by using as a backing plate a sheet made of low-carbon steel, 10 [mm] thick, of smooth surface and with the force acting perpendicularly, in room temperature.
The presence of an air gap (distance) between the magnet and the backing plate reduces the attractive force.
The material, of which a backing plate is made affects the force of attraction (the higher carbon proportion in steel, the smaller pull force).
The quality of the surface of the backing plate is also of great importance (the smoother the surface, the greater the bigger pull force).
The highest lifting capacity is obtained the biggest pull force is obtained with perpendicular acting of detaching force, with acting of detaching force, with parallel force action, the load capacity value is 20% of the maximum.

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. Direction of magnetization along the height.
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. It has been manufactured to excellent dimensional tolerances.
The maximum operating temperature is no more than 110 degrees Celsius.
Ferrite magnets stick to metal surface (ferromagnetic materials).
