Description

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.

Key Features

  • High-Grade NdFeB (N52 equivalent) magnetic material for superior field strength.
  • Axial magnetization direction for consistent and predictable field orientation.
  • Precision-machined round shape with clean inner and outer diameters.
  • Protective silver plating mitigates corrosion in standard indoor environments.
  • Optimized performance-to-cost ratio for prototyping and small-batch production.
  • Durable construction suitable for integration into mechanical assemblies and electronic enclosures.

Applications

  • Reference magnet for calibrating Hall effect sensors and magnetometers in IMU modules.
  • Actuation component for magnetic reed switches in security systems and proximity detection.
  • Magnetic coupling or holding element in small mechanical assemblies and prototype devices.
  • Component in DIY sensor projects for Arduino, Raspberry Pi, or ESP32 involving magnetic field detection.
  • Attachment magnet in specialized corrective or dental devices requiring a strong, compact hold.

Frequently Asked Questions

What is the polarization direction of the K800 magnet?

The K800 magnet is axially magnetized. This means its magnetic north and south poles are on the flat, circular faces of the ring, not through the inner diameter. This polarization is standard for use with Hall effect sensors and reed switches.

Is this magnet suitable for outdoor or humid environments?

The silver coating provides basic protection against oxidation and corrosion in standard indoor conditions. For prolonged exposure to humidity, moisture, or outdoor elements, additional sealing or a magnet with a more robust coating (e.g., nickel, epoxy) is recommended, as NdFeB magnets are susceptible to corrosion.

Can this magnet be used to calibrate a Hall effect sensor module?

Yes, its consistent axial field and known dimensions make it a suitable reference magnet for calibrating the sensitivity and offset of linear Hall effect sensors. Ensure the sensor is positioned correctly relative to the magnet's poles to map the magnetic field strength accurately.
