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 1 kg.

The answer to why you can arrange pot magnets only side by side can be found under our FAQ.
Here you can see the difference between a CSN and a CSN-ES magnet. Although both types have similar dimensions on the outside, the CSN-ES has a thicker steel pot (in grey) and a slightly smaller magnet. This leads to an overall stronger adhesive force, despite the smaller magnet, because the metallic adhesive surfaces are larger.
Since the new CSN-ES magnet is too strong for some of our customers, we also offer the somewhat weaker CSN-alternative.
