This pot magnet has the same dimensions as CSN-20, but with a thicker steel pot and, hence, a higher adhesive force. It can be fastened with a countersunk screw. This extra-strong pot magnet has proven itself especially in the field of shopfitting, kitchen and bathroom installations, electrical engineering and product development.

The following screws fit into the CSN-ES-20, for example:

  • Slotted countersunk wood screw: DIN 97 (3,5 mm)
  • Cross recessed countersunk flat head screws (machine screw): ISO 7046-2 M3 (3 mm)
  • Countersunk torx screws/hexalobular socket (machine screw): ISO 14581 M3 (3 mm)
  • Hexagon socket countersunk flat head screws (machine screw): ISO 10642 M3 (3 mm)

PDF data sheet
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 2 kg.
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.
The answer to why you can arrange pot magnets only side by side can be found under our FAQ.
