Neodymium ring magnet 20 x 9.8 x 5.1 mm – epoxy coated with countersink hole (North Pole)

with drill/sink hole (north pole)

This neodymium ring magnet has an outer diameter of 20 mm, an inner diameter of 9.8 mm, and a thickness of 5.1 mm. The magnet has a countersunk borehole on the top, allowing you to easily attach it to various surfaces with a screw. This model's north pole is on the countersunk side – important for applications where polarization is directionally sensitive.

The magnet is made of powerful neodymium , which guarantees very strong magnetic force despite its compact size. The robust epoxy coating (Ni-Cu-Ni-EP) protects against corrosion, moisture, and wear, making the magnet suitable for use in humid or demanding environments.

This ring magnet is ideal for permanent mounting in furniture, displays, technical installations, or as a concealed mounting solution in wood or metal. Thanks to its recessed mounting, the magnet lies flat after installation.

Specifications:

• External dimensions: Ø20 mm

• Inner diameter: Ø9.8 mm

• Height: 5.1 mm

• Drill hole: Countersunk for screw mounting
