Physical Properties of Ferrite Magnets
Remanence (Br): 3.8 – 4.3 kG (380 – 430 mT)
Ferrite magnets maintain moderate remanence, providing a stable magnetic field suitable for continuous operation without excessive magnetic loss.
Coercivity (Hci): 2.4 – 3.8 kOe (190 – 300 kA/m)
Their high coercivity ensures strong resistance to demagnetization, even under high-temperature or alternating magnetic field conditions.
Energy Product ((BH)max): 3.0 – 4.3 MGOe (24 – 34 kJ/m³)
The energy product reflects the magnet's ability to store magnetic energy efficiently, balancing cost and performance for industrial applications.
Curie Temperature (Tc): 450 – 460°C
With a high Curie temperature, ferrite magnets retain magnetic stability in high-temperature environments, making them suitable for automotive and industrial motors.
Ferrite magnets combine excellent thermal stability, corrosion resistance, and cost efficiency, ensuring reliable performance and long service life across various industrial and electronic applications.
FAQ
What are the advantages of using ferrite magnets in position sensors?
Ferrite magnets offer excellent magnetic stability, corrosion resistance, and cost-effectiveness. They perform reliably in harsh environments and provide consistent signal accuracy, making them ideal for industrial and automotive sensor applications.
What temperature range can ferrite magnets operate in for position sensors?
Ferrite magnets typically operate effectively between -40°C and +250°C, depending on the grade. This wide range ensures stable performance even in high-temperature or outdoor sensor applications.
Do ferrite magnets require any coating for protection?
No. Ferrite magnets are inherently corrosion-resistant and do not require any surface coating, making them ideal for long-term use in demanding or humid environments.
