Neodymium Ring Magnet - (OD)20mm x (ID)4mm x (H)12.7mm
Product code: 23014
Neodymium Ring Magnet - (OD)20mm x (ID)4mm x (H)12.7mm
Magnetic Product Description:
This rare earth ring magnet has an outside diameter of 20mm, an inside diameter of 4mm and a height or thickness of 12.7mm. It has a pull force of 11.8kg. It is identified by the AMF Magnet part number 23014.
Uses for our Rare Earth Rings Magnets:
Neodymium Ring Magnets are in many circumstances the strongest and most practical of magnet shapes. The central hole or void area provides a convenient attachment point to other surfaces and also enables the magnet to slide over locating pins or shafts in a wide range of measuring devices or monitoring instruments like valves, gauges and switches. Mechanical anemometers, for instance, use magnets to activate reed switches in a rotating wind vane. This information is calibrated and used to determine wind speed for meteorological purpose or for navigation. These powerful ring magnets have many practical applications and are used widely in the agriculture, engineering and telecommunication industries.

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.
