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, usually made of galvanized steel or 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
You can therefore adapt the deep pot magnets perfectly to your needs. Kategorietext
The magnetic core of the deep pot magnet
The magnetic cores of the deep pot magnets 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 deep pot magnets have a different adhesive force and react differently to high temperature requirements. Neodymium magnets are extremely adhesive - which is why they are also referred to as super magnets.
Alnico magnets, on the other hand, are characterized by a good adhesive force, but in this respect, they cannot even compete with neodymium magnet deep pots. Samarium-cobalt systems are between the other two magnet systems in terms of power development. Regarding temperature resistance, on the other hand, the situation is exactly the opposite. Alnico systems tolerate the most heat, neodymium systems the least heat development. The magnets reach the following maximum operating temperatures: NdFeB 80 °C / SmCo 250 °C / AlNiCo 450 °C.
Deep pot magnets in general are characterized by the fact that they only have one adhesive surface as a magnetic head. As a result, they develop a particularly precise and pinpoint force effect - for example, they do not attract any small, magnetic particles that are outside the fixed area. Deep pot magnets therefore work very cleanly.
Important: The pole faces of the magnetic deep pots should always be clean. This guarantees maximum effectiveness when you apply it or detach it from surfaces.
What are the uses for deep pot magnets?
The possible uses for deep pot magnets are very diverse.
Obvious professional 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. However, the deep pot magnets systems are optimized for use as industrial magnets and are preferably used in mechanical engineering or tool making. The SmCo, AlNiCo or neodymium deep pot magnets fix, fasten and transport workpieces without any problems. Accordingly, they replace complex clamping devices.
What do you have to pay attention to when installing magnetic deep pots?
When installing the deep pot, it is important to ensure that it is not directly surrounded by iron. The iron reduces the holding power or adhesion by up to 15 percent. It doesn't matter whether the casing 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 power can also be reduced if the magnets are used on uneven, painted, or thin surfaces.
You can buy these types of deep pot magnets
In our shop you can choose between different types of housings and magnetic cores. As already described, the cores are made of neodymium, AlNiCo or SmCo. When it comes to the housing, you can choose between those made of brass and those made of steel. The heat and corrosion resistance varies depending on the material. For example, the AlNiCo deep pot magnets with steel housing are particularly heat-resistant. These can be used at temperatures of up to 450 °C.
What else needs to be considered with rod grippers?
The use of strong magnetic fields can directly affect electronic devices such as:
- Clocks digital
- Storage Media
- EC cards
To avoid data loss and damage, a safety distance of at least one meter is recommended. Pacemakers and electricity and gas meters are also affected by this problem.
To ensure that the holding magnets remain functional, you must not saw, file, or drill through them. A fall on the ground can also have a negative effect if the magnetic cores shatter.
