Countersunk pot magnet

Ø 25 mm, strength approx. 19 kg
promptly deliverable


This magnet in a steel pot has a countersunk borehole and can be fastened with a countersunk screw. Its design is identical to CSN-25, but this magnet is heat-resistant up to 150°C. This makes it especially suitable for lamp design and in industrial furnaces for attaching coated or glued items.

The answer to why you can arrange pot magnets only side by side can be found under our FAQ.
The graph shows the maximum adhesive force in kg (y axis) at various distances in mm (x axis) between pot magnet and counterpart (steel plate).
Example: At a 1 mm distance between pot magnet and steel plate the maximum adhesive force is still 4 kg.
