Confirm pole orientation, operating air gap, sensor threshold, temperature exposure, adhesive selection, and dimensional stack-up in the final assembly. Sintered neodymium magnets are hard and brittle, so avoid impact, snap-together collisions, uneven clamping, and excessive mechanical stress.
The listed 1.74 lb pull force is a comparison value under defined contact conditions, not a guaranteed safe working load. Air gaps, surface roughness, coating, thin target steel, temperature, and shear loading can reduce usable force.
Use the magnet pull force calculator for preliminary magnet-to-steel screening and compare material options in the neodymium magnet grades chart. Browse our magnet catalog or submit the magnet RFQ builder for volume pricing or a custom requirement.
