Magnet Introduction
The BMAG Neodymium Donut Magnet N40 features a large central aperture, making it perfect for shaft-mounted sensors and magnetic couplings. The N40 grade ensures a high-density magnetic field concentrated around the ring. We maintain a 0.02mm tolerance on the ID and OD to ensure balanced rotation.
BMAG can help customers test the magnetic field and magnetic flux, ensuring that the N40 material provides a stable flux path for high-precision positional sensing or torque transmission.
Available with customizable plating materials. Standard finishes are nickel-plated unless otherwise specified.
