Brand: YXMAGNET

Multipole Magnetize N42H Round Ring Annular — N42H. Neodymium disc magnets made by YXMAGNET: N35–N52 rare-earth NdFeB, Ni-Cu-Ni / zinc / epoxy / nickel coatings, axial, diametral or radial magnetization, ±0.05 mm tolerance (±0.02 mm on small or critical features), suited to motors, sensors, electronics and fixturing. OEM/ODM, custom magnetization and volume pricing direct from our Dongguan factory. Request a quote or sample.

Available magnetisation directions — Ring magnets

The magnetisation direction is fixed when the magnet is magnetised and cannot be changed afterwards, so the direction must be confirmed before production.

Axially MagnetizedPoles are on the two flat end faces of the ring.
Diametrically MagnetizedPoles are split across the ring — one half is N, the other half S.
Multi Axially MagnetizedAlternating N and S poles around the circumference — pole count to your drawing.

Manufacturing capability & measured data

Tolerance

Standard production: ±0.05 mm
Critical dimensions (on request): ±0.02 mm

Quoted per dimension against international dimensional quality standards, not as one blanket percentage. ±0.05 mm is the standard band; where a drawing calls for more, critical dimensions are held to ±0.02 mm using grinding or wire-cutting. The final tolerance is confirmed against your drawing before production.

Salt spray

Duration depends on coating: 12 – 96 h

Tell us how many hours your application needs and we match the coating to it. The test standard and the hours each coating reaches are confirmed on request.

Lead time

Sample: 10 – 15 days
Small batch: 20 – 30 days
Mass production: 40 – 60 days

Bands are by order type, not a single quantity threshold; exact lead time is confirmed at quotation.
