Diametrical magnetization places the north and south poles on opposite sides of the curved cylindrical surface instead of the flat faces. That field orientation is commonly evaluated for rotary position sensing, speed detection, commutation, encoder-style systems, and proximity-sensing geometries where the magnetic vector must track predictably through rotation.
The listed 3° maximum magnetization-angle deviation is especially relevant in applications where magnetic-vector alignment affects sensor output. The listed surface field and pull force remain reference values; actual operating results depend on sensor location, air gap, surrounding materials, temperature, and assembly tolerances. Review the magnetization guide when comparing diametrical, radial, and segmented field orientations.
SKU 9042 is well suited to repeat production where sorted magnetic orientation and compact metric dimensions matter. Browse stocked sensor magnets for related sizes, compare material options using the Neodymium Magnet Grades Chart, or use the Magnet RFQ Builder for custom geometry, magnetic orientation, tolerance, coating, or production-volume requirements.
