Neodymium cylinder magnets have unique properties that give them specific abilities in many high-tech applications. Neodymium cylinder magnets produce a narrow, deep magnetic field, emitted through the flat surface at each end of the cylinder. This characteristic is highly valuable in high tech applications where their small size and strong holding power are extremely important to performance. Switch mechanisms, safety systems, alarms and sensors are all magnetic products that require cylinder magnets to activate them. These permanent Neodymium magnets operate independently without the requirement of external power sources. Unlike mechanical switches, cylinder magnets have virtually no moving parts, reducing the likelihood of failure over time or with extended use.
Despite their relatively tiny size, these small Neodymium cylinders are deceptively strong and immensely useful. In an application where they are in proximity to steel or electromagnetic fields, the cylinder magnets can be used to open or close electrical circuits. Reed switch equipment often has a vacuum-sealed switch that is never exposed to corrosive atmospheres, which greatly improves their long-term reliability. Another bonus with permanent Neodymium cylinder magnets is that the magnetic force can penetrate non-magnetic surfaces to operate a switch remotely. The motor vehicle industry has made enormous innovative advances based on this contactless method of activation, to operate warning and safety systems. A vast range of appliance and computer on/off switches can be operated with magnetically operated reed switches, making these small Neodymium cylinder magnets valuable to a multitude of industries.

Surface Treatment
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.
Range and Tolerance
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.
Magnetic Properties
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.
