Through-thickness magnetization places the poles on the broad 20 × 5 mm faces. The 2 mm thickness makes this a low-profile rectangular option for linear sensor targets, magnetic latches, compact fixtures, positioning elements, and embedded OEM features.
The listed pull force and surface field are reference measurements under controlled conditions. Air gap, steel thickness, surface finish, temperature, contact area, and load direction can all change usable force. Use the Magnet Pull Force Calculator for preliminary screening and the Neodymium Magnet Grades Chart for material comparisons.
