The K800 is a precision-engineered, axially magnetized neodymium ring magnet. Its NdFeB composition delivers a high strength-to-size ratio, making it suitable for applications where space is constrained but a reliable magnetic field is required. The silver coating enhances durability by protecting the core material from environmental corrosion.
This magnet is commonly used as a reference component in sensor systems, such as calibrating Hall effect sensors or serving as the actuating element in magnetic reed switches. Its defined axial polarization and consistent geometry ensure predictable magnetic field lines, which is critical for repeatable performance in measurement and holding applications.
