High tolerance neodymium rare earth block, cube & square magnets, N42 grade Guaranteed tolerances for repeatability with exceptional pricing.
Where indicated, all our neodymium magnets are fully sintered & individually pressed to optimize uniformity of magnetic orientation & are manufactured according to National Magnetic Standards. This ensures that strength variation of +/- 5% between magnets is met both within batches & from batch to batch. You can be certain that our magnets will make your sensors, switches & latches work reliably & according to design.
