This rectangular rubber coated magnet is 52mm x 32mm x 6mm with a Neodymium (NdFeB) magnetic core, and a Santoprene rubber coating that protects delicate surface areas. It has two D5mm boreholes, each with a D10mm counterbore. This Rare Earth magnet weighs 40 grams. It is identified by the AMF magnet part number RCNL52B.
This rubber-coated Neodymium magnet is strong and versatile. The rubber coating gives these magnets immense durability and also the ability to withstand harsh environments that would otherwise damage the fragile magnet inside. The rectangular magnet has two convenient recessed mounting holes that allow it to be attached with standard hardware such as bolts or screws. The strong Neodymium magnet inside the rubber casing means this product is both powerful and gentle to attach. The superior quality Santoprene rubber prevents marks and scratches on delicate surfaces so these magnets can be successfully attached to either side of glass windows without damaging the glass or window tint material. Rubber coated magnets are commonly used to attach signs, mementoes or memorabilia to painted or easily damaged metallic surfaces. They are particularly popular for attaching objects to cars and trucks, mining equipment, boats, buses, caravans, shipping containers and demountable buildings.

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.
The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
