Description

Bestseller: More than 1 600 000 sold!
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 proved itself especially in the areas of store construction, kitchen/bath design, electronic engineering and product development.

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 following screws fit into the CSN-20, CSN-ES-20, as well as CSN-HT-20:

  • Countersunk wood screw with groove: DIN 97 (3,5 mm)

  • Recessed countersunk flat head screws (machine screw): ISO 7046-2 M3 (3 mm)

  • Countersunk torx screws (machine screw): ISO 14581 M3 (3 mm)

  • Hexagon socket countersunk flat head screws (machine screw): ISO 10642 M3 (3 mm)
