Design and application notes

This magnet is magnetized through its 5 mm thickness, so the 40 × 10 mm faces are the working pole faces. That elongated pole geometry can be useful in linear fixtures, equipment stops, magnetic catches, test assemblies, and applications where a long rectangular field footprint is preferable to a disk.

The listed pull-force value is a comparison value under defined contact conditions, not a guaranteed safe working load. Air gap, adhesive layers, target-steel thickness, surface roughness, temperature, curvature, and shear loading can all reduce usable force. Use the Magnet Pull Force Calculator for preliminary screening and the Neodymium Magnet Grades Chart when comparing grades.
