Deep pot magnets with different housings and different magnetic cores
A deep pot magnet is a magnet system. The magnet is housed in a cylindrical housing, which is usually made of galvanized steel or the copper-zinc alloy and brass. The magnet systems can be glued in, pressed in, or shrunk in. When you buy deep pot magnets, you can choose between different shapes: with internal thread / as a pin / as a threaded pin / without fit tolerance
The magnetic core of the deep pot magnet
The magnetic cores of the bar grippers are made of neodymium (NdFeB), samarium-cobalt (SmCo) or alnico (AlNiCo) - an alloy of aluminum, iron, copper, nickel, and cobalt. Depending on the material used, the gripping magnets have different adhesive forces and react differently to high temperature requirements. Neodymium magnets are extremely adhesive - therefore they are also referred to as super magnets.
Alnico magnets, on the other hand, are characterized by a good adhesive force, but cannot even come close to competing with neodymium magnet rod grippers in this regard. Samarium-cobalt systems lie in force development between the two other magnet systems. Regarding the temperature resistance, however, it is exactly the opposite. Alnico systems tolerate the most heat, neodymium systems the least amount of heat.
The magnets reach the following maximum operating temperatures: NdFeB 80 ° C / SmCo 250 ° C / AlNiCo 450 ° C.
What are the possible uses for deep pot magnets?
The possible uses for deep pot magnets are very diverse. Obvious occupational fields are, for example:
- Semiconductor Technology
In addition to commercial applications, the magnet systems also serve as a practical aid in the private sector to attach or fix objects. The deep pot magnet systems are, however, optimized for use as industrial magnets and are preferably used in mechanical engineering or tool making.
What do you have to pay attention to when installing deep pot magnets?
When installing the deep pot magnet, it is important to ensure that it is not directly surrounded by iron. In this case, the adhesive force or adhesion is reduced by up to 15 percent. It does not matter whether the housing is galvanized or made of brass. A minimum distance of several millimeters between the housing and the surrounding iron solves this problem. The optimal distance varies but is usually specified by the manufacturers. The holding force can also be reduced if the magnets are used on uneven, painted or thin surfaces.
What needs to be considered with deep pot magnets?
The use of strong magnetic fields can have direct effects on electronic devices such as:
- Clocks, digital
- Storage media
To avoid data loss and damage, a safety distance of at least 1 meter is recommended. Pacemakers as well as electricity and gas meters are also affected by this problem.
To ensure that the holding magnets retain their functionality, you must not saw, file, or drill through them. A fall on the floor can also have a negative effect if the magnetic cores shatter.
