Recessed pot magnet, Ø25 mm. - Ferrite
Description
Description
Pot magnet with ferrite core and screw hole for countersunk screw head.
The magnet has a carrying capacity of approx. 2.2 kg.
Although ferrite is nowhere near as strong as neodymium (this is almost 90% weaker than Ø25 neodymium magnet), there are still some clear advantages to choosing a ferrite pot magnet:
- Can be used outdoors
- Cheap alternative to neodymium magnet
Ferrite magnets are often used outdoors because they better withstand direct sunlight, and they do not rust despite wind and weather. But you must be aware that the steel pot can get a thin layer of rust - this does not affect the magnetism, however.
SPECIFICATIONS
Diameter: 2.5 cm.
Height: 7 mm.
Screw hole: ø 5.5 mm. (M5)
Strength: approx. 2,200 g.
Magnetism: Y30BH
Steel pot: Q235
Max. temperature: 50°C
The steel pot has 2 functions: reinforces the magnetism and holds the magnet so that it is more resistant to impacts.
The strength of these pot magnets with ferrite is measured directly on a strong, magnetic steel plate. The carrying capacity weakens the further the magnet comes from the magnetic surface.
Be aware that magnets always have the strongest pull on a horizontal surface, as the magnet slides easily on a vertical surface, while a vertical pull on the magnet places higher demands on the magnet, as it is not a direct pull.
Please contact us for strength requirement calculations if you need a distance to the magnet or it needs to be set up vertically - both require a lot of the magnet and quickly weaken the magnet with 75% or more.
Ferrite magnets are not suitable for glass boards.
