Ferrite Rod Magnet 6x20mm

Ferrite magnets for industrial drive systems are designed to provide stable magnetic performance and long-term reliability in demanding industrial environments. Manufactured from high-quality ceramic ferrite materials, these magnets offer strong resistance to demagnetization, high electrical resistivity to reduce eddy current losses, and good thermal stability for continuous operation. With natural corrosion resistance and no need for surface coating, ferrite magnets are well suited for drive motors, gear motors, and various industrial motion control systems.

Magnetic Structure & Working Principle

Ferrite Rod Magnet 6×20mm uses axial magnetization along the 20 mm length direction, generating magnetic flux from both circular end faces of the rod structure.
The cylindrical magnet is commonly inserted into plastic housings, sensor assemblies, or magnetic positioning systems where compact magnetic field distribution is required.
During operation, the magnetic field interacts with reed switches, Hall sensors, or nearby ferromagnetic components to trigger switching, sensing, or positioning functions.
The 6 mm diameter rod structure helps concentrate magnetic flux within a compact installation space while maintaining stable alignment inside assembled components.

OEM & Custom Manufacturing

Custom diameter, length, and magnetic strength can be manufactured according to sensor structure, motor assembly, or magnetic positioning system requirements.
Multiple magnetization options are available, including axial magnetization and customized magnetic orientation for different sensing and switching applications.
OEM drawing-based production supports sample development, batch manufacturing, and dimensional tolerance control for integration into plastic housings, metal sleeves, and industrial magnetic assemblies.
