Design and application notes

The two flat circular faces are the working pole faces. In very small assemblies, mechanical tolerance, air gap, sensor position, and nearby steel can strongly affect the useful magnetic field.

The listed pull force is a reference value under controlled conditions. Use the Magnet Pull Force Calculator for preliminary screening and the Neodymium Magnet Grades Chart when comparing material grades.
