Neodymium Cylinder Magnet - 11mm x 30mm

Magnetic Product Description:

This neodymium cylinder has a diameter of 11mm and a height of 30mm. It has a magnetic flux reading of 6197 Gauss and a pull force of 5.1kgs. It is identified by the AMF magnet part number 21021.


Uses for our rare earth cylinder magnets:

For the sure and true regulation of moving parts, for the turning of moving parts, magnets, like these 11mmx30 neodymium cylinders, when used in locks for doors and gates of all kinds deliver the certitude necessary for peace of mind.

The word turnkey was originally used to describe a person who held the keys to the jail. Today the word turnkey is used to describe a good or service which is assembles and installed by a supplier ready for operation. Turnkey solution. When a no excuses mechanism is needed to keep valuables like cash and jewellery locked in a safe, magnets are often used to regulate the gate open/gate close function on locks of many kinds.

From the simplest of locks to sophisticated voice activated electronic security locks, magnets have been relied on for the certainty magnetic force provides. Magnets, including these neodymium 11mmx30mm cylinders, apply their intuitive pull and push force, in hold and release functions, over and over again, time after time.

Locksmiths and safe makers design and secure, with the assistance of magnets, devices that defeat even the most persistent unauthorised individuals. Rely on the power of magnets to regulate the opening and closing function of gates and doors to authorised personnel only.

Industries that use this magnet are: railway track maintenance and construction, catering, medical equipment manufacturers, analytics software developers, lubricant and oil filter manufacturers, installation and maintenance engineering.

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.
