Neodymium Cylinder Magnet 2.7mm x 5mm N52 | Diametrically Magnetized | Parylene-C Coating
Precision-engineered for advanced technical and specialised applications, this Neodymium Cylinder Magnet measures 2.7mm in diameter x 5mm in height and is manufactured from premium N52-grade rare earth neodymium — one of the strongest commercially available magnet grades. Featuring a diametrically magnetized orientation and a high-performance Parylene-C coating, this miniature cylinder magnet is ideal for precision engineering, medical devices, electronics, sensor systems, and high-tech manufacturing applications.
Unlike standard axially magnetised cylinder magnets, this magnet is diametrically magnetized, meaning the north and south poles are located on opposite sides of the curved cylinder surface rather than on the flat ends. This specialised magnetisation pattern makes it particularly suitable for rotary sensing systems, motors, encoders, couplings, and precision positioning applications.
The advanced Parylene-C coating provides a thin, uniform protective barrier with excellent resistance to moisture, chemicals, corrosion, and harsh environments. This coating is commonly used in sensitive electronic, medical, scientific, and aerospace applications where traditional nickel coatings may not be suitable.
Its compact dimensions combined with ultra-high N52 magnetic strength make this magnet an excellent choice for applications requiring powerful magnetic performance in an extremely small and specialised form factor.

Please Note
Neodymium magnets are extremely strong for their size and should be handled carefully. Small magnets can present a swallowing hazard and must be kept away from children. Avoid allowing magnets to collide forcefully, as they may chip or crack upon impact. Parylene-coated magnets should also be handled carefully to preserve the integrity of the specialised coating.

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. We 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.
