Product code: 20080
This Rare Earth disc has a diameter of 4.75mm and a height of 1.5mm. It has a magnetic flux reading of 3364 Gauss and a pull force of .290kg. Its part number is 20080.
These Rare Earth discs are mostly used for holding lightweight materials like artwork and decorations but are increasingly found in modern-day digital technologies like audio equipment, communications devices and computer hard drives. They are also an appropriate size and strength for brochure and binder closure mechanisms.
Neodymium Disc Magnet - 4.75mm x 1.5mm (20080)
NB: Ranges are indicative for product category, please check individual products for specic values within that range.
The most common coating for Neodymium magnets is Nickel + Copper + Nickel (Ni + Cu + Ni). This coating offers the magnet relatively good protection from corrosion and passive applications. If the magnet will be exposed to moisture or liquid then consider the use of an organic coating such as Epoxy. A hard wearing coating, Epoxy is suited to applications where the magnet will come under some friction or knocking.
Magnets are readily available in Blocks, Discs, Cylinders & Rings. AMF Magnetics specializes in the supply of short-run prototype magnets including Arc Segments, various magnetic orientations etc. If you need a magnet size that we don't carry in stock, submit a Design-a-Magnet enquiry for a quote on your custom magnet design.
Neodymium magnets are offered in several different grades. The first section N30-54 has an operating temperature of up to 80 degrees. Most of our stock only goes up to N38. The second section, denoted with the "M" prefix after the grade has an operating temperature 100 degrees. After this the grades are "H", "SH", "UH" & "EH". In order for the magnet to withstand a higher operating temperature, during production more of the raw material PrNd is incorporated as these elements have a naturally occurring resistance to high temperatures.

Super happy with these magnets, they were the perfect size I needed, however, they are kind of fragile, and I broke a couple when they snapped back onto the stack of magnets I had on the table. D'OH.
The magnets I got were perfect for the task, information to understand,easy to order and fast delivery what else you can say.
Attached to HO scale model train to activate magnetic Reed Switches.
Awesome service super fast delivery, product exactly as described, excellent quality. Very happy.
