Functioning of the neodymium pot magnets with steel pot: The strong NdFeB magnets are installed in a steel pot. This metal housing protects the neodymium magnet from damage and increases the adhesive force. In order to achieve an optimal adhesive force, the pot magnet must rest directly on the metallic surface. A thin sheet of iron or paint can reduce the adhesive force very quickly. The adhesive force only acts on the open magnet side, since the steel pot shields the magnetic effect.
Special feature: The magnet has a central hole with a counter bore. This allows the holding magnet to be securely screwed to the wall / ceiling using a countersunk screw. Metallic counterparts then adhere magnetically to this pot magnet. The maximum operating temperature is 80 ° C.
The holding magnets / assembly magnets / pot magnets are used particularly often in industry, trade fairs and assembly. The strong pot magnets are also indispensable in the advertising sector / display construction / lighting sector. Neodymium Pot Magnet with Countersunk Hole 80mm
NdFeB Pot Magnet with countersunk mounting has a countersunk hole as well in the front face makes it easy to fix in countersunk screw (M4, M5 and DB ). These magnets also idle for using many applications such as sale displays, marketing displays, doors, panels, and false ceilings.
*Firm bolting with subsurface
*Use as holding, mounting or cup magnet
*Especially suitable for structural solutions in metal, plant or booth construction as well as in the lighting industry.
