Design and application notes

Axial magnetization places the poles on the two flat circular faces. The 12 mm diameter × 3 mm profile is useful in compact magnetic catches, sensor targets, alignment features, small fixtures, prototypes, and embedded assemblies.

The listed 4.19 lb pull force reflects controlled contact with suitable steel; actual holding force varies with air gap, target material, surface condition, temperature, and load direction. Use the Magnet Pull Force Calculator for preliminary application screening and the Neodymium Magnet Grades Chart when comparing grades.
