About the Product

Neodymium disc magnets are a compact, high-energy format used for sensor prototypes, closures, and robotic fixtures. The round footprint seats cleanly in counterbores and adhesive pockets, with consistent thickness tolerance for reliable stack-ups. Standard axial magnetization provides predictable pull to steel. During test-fit, use the Pull Force Calculator to estimate holding force and select coatings appropriate to the environment; consult material data when evaluating grade and thermal behavior.
