N35 neodymium disk magnet, 1/2 inch diameter × 1/16 inch thick, with Ni-Cu-Ni plating and 3M tape on the north-pole side. Axially magnetized. Listed pull force: 2.36 lb. SKU 8686.
The thin disk provides a broad circular face for compact mounting and closure assemblies. Axial magnetization places its poles on the flat circular faces. Check which pole must face the mating component before installing the adhesive-backed side.

Adhesive mounting and assembly
The tape is on the north-pole side. Verify substrate compatibility, surface preparation and adhesive performance under the intended temperature and loading direction. Magnetic pull and adhesive bond strength are separate limits; the listed magnet temperature does not establish a rating for the tape. Support the thin disk during placement and avoid bending or impact.
Listed pull force is a comparison value rather than a safe working load. Target steel thickness, air gaps, surface condition and loading direction affect actual holding force. Test the complete assembly at its intended working gap and temperature before production.
The listed maximum magnet temperature is 80°C. Allowable operating conditions depend on the magnetic circuit and opposing fields; check adhesives and housing materials against their own limits.
