Design and application notes

Through-thickness magnetization places the north and south poles on the broad 25 × 5 mm faces. The elongated geometry is useful in compact linear sensor targets, magnetic catches, fixture stops, alignment features, and embedded OEM assemblies.

The listed pull force and surface field are reference values under controlled conditions. Air gap, target steel, contact area, surface finish, temperature, and load direction all affect installed performance. Use the Magnet Pull Force Calculator for preliminary screening and the Neodymium Magnet Grades Chart when comparing grades.
