SuperMagnetMan Neodymium Cylinder Magnet.  Used as medical magnets, holding magnets, sensor magnets, consumer electronics magnets.  These cylinder magnets are strong rare earth neodymium magnets also used as automotive magnets.

0.197" (5mm) dia x 0.394" (10mm) long, N40 Rare Earth Neodymium Cylinder / Rod Magnet, Magnetized across the diameter, Gold Plated.

Minimum Order Quantity (MOQ) = 15 pcs

Common Applications:  Medical devices, sensors, consumer electronics, and holding applications

About Small Cylinder Magnets:  Defined with a diameter between 0.040” (1.016mm) – 0.250” (6.35mm).  The diameter and the length will determine the reach and profile of the magnetic field and performance of the cylinder magnets. 

Direction of Magnetization (DOM): Cylinder Magnets are manufactured so the DOM is set during the manufacturing process and cannot be changed. Available options during manufacturing for DOM:

  1. Through the thickness
  2. Across the diameter

Magnetic Grades:  To view a table of grades and specs, see our Neodymium Magnet Grades & Specs

About Gold Coating on Magnets:

  • FDA approved medical coating for in-body use
  • Has an undercoating of Ni-Cu-Ni
  • Protection of the magnet from corrosion in ambient air
  • Slight protection from humidity, water, or salt water. The thickness of the gold is very thin, so performance in salt spray tests will ultimately show failure of the coating.  Making the coating thicker will help, but gold is intended to be thin.
  • Gold finish
  • Thickness of gold layer: 0.3-0.6 micron
  • Cost: High
  • Max working Temp: Approximately 200o C
  • Main Industries: medical (in and out of body applications), jewelry, decorative uses.
