0.039" (1mm) OD x 0.020" (0.50mm) ID x 0.020" (0.50mm) thick, Set of 10. N50 Rare Earth Neodymium Ring Magnet, magnetized through thickness. Nickel Plated. 

Minimum Order Quantity (MOQ) =  1 set

Common Applications:  Motors, medical devices, automotive, robotics, sensors, consumer electronics.

About Small Ring Magnets:  Defined with an outside diameter (OD) equal to or less than 0.250” (6.35mm).  The outer diameter (OD), inner diameter (ID), and thickness will determine the reach and profile of the magnetic field and performance of the ring magnets.

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

  1. Through the thickness
  2. Across the diameter
  3. Multiple poles on the face of the magnet
  4. Radially magnetized, with a single pole or multiple pole on the OD and ID

About Nickel Coating on Magnets:

  • Most common coating on magnets
  • Actually 3 layers, nickel-copper-nickel
  • Protection of the magnet from corrosion in ambient air
  • Not a protective coating from humidity, water, or salt water
  • Light protection of the magnet from chipping
  • A decorative finish
  • Shiny metallic gray finish
  • Thickness: 12-25 microns
  • Cost: Low
  • Max working Temp: Approximately 200oC
