Design and application notes

Axial magnetization places the north and south poles on the two flat circular faces. The 20 mm diameter gives this part a broad metric pole face while the 3 mm thickness keeps the profile compact for closures, sensor targets, positioning features, test fixtures, and embedded assemblies.

The listed pull force and surface field are reference values under specific test conditions. Air gap, mating-steel thickness, contact area, surface finish, temperature, and pull direction all affect real-world performance. Use the Magnet Pull Force Calculator for preliminary screening and the Neodymium Magnet Grades Chart when comparing grades.

Procurement and custom sourcing

SKU 9351 is suited to repeat metric production where a documented stock size simplifies sourcing and BOM control. Browse stocked neodymium disk and rod magnets for nearby sizes, or use the Magnet RFQ Builder for custom diameter, thickness, coating, tolerance, magnetization, or production quantities.
