9782 – N35 Neodymium Ring Magnet 12 x 4 x 4 mm

SKU 9782 is an N35 neodymium ring magnet measuring 12 mm OD × 4 mm ID × 4 mm thick. Axially magnetized through the thickness, it provides engineers, OEMs, and procurement teams a compact metric annular magnet for holding, sensing, alignment, shaft clearance, mounting, and magnetic-circuit applications.

Specifications

Metric ring design notes

This ring is axially magnetized through its 4 mm thickness, placing the poles on the two broad annular faces. The 4 mm center opening can provide clearance for a shaft, pin, or fastener, but avoid interference fits and excessive clamping because sintered neodymium is brittle.

The listed pull force is a reference value under controlled conditions. Use the Magnet Pull Force Calculator for preliminary screening and see Ring and Annular Magnets for geometry guidance.
