12mm x 2mm (15/32" x 5/64") Neodymium Disc Magnet – N52 Grade 

Key Features:

• Dimensions: 12mm Diameter × 2mm Thickness
• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52 
• Pull Force: Approx. 4.2 lbs 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating
• Magnetization: Axially magnetized (Poles on the flat circular faces)
• Surface Gauss: Approx. 2,298 Gauss

Material Description:

Our 12x2mm N52 discs are designed for professional engineering and structural applications that require a robust "snap" without adding significant thickness. The 2mm depth allows the magnetic field to penetrate through thicker materials compared to ultra-thin discs, making these ideal for "invisible" latches behind wood veneers or plastic panels. The 12mm diameter provides a stable base that resists lateral shifting, ensuring your components stay perfectly aligned.

Handling Advice: NOTICE: These magnets are surprisingly strong for their size. With over 2.5 lbs of pull force, they can snap together with enough velocity to shatter or cause minor skin pinches. Always separate them by sliding the top magnet off the stack horizontally and avoid letting them slam into ferrous surfaces.

Warnings and Safety Information:

• Pinch Hazard: Strong enough to cause painful skin pinches. Handle with a steady, firm grip.
• Choking Hazard: Keep strictly away from children and pets; small size is a major ingestion risk.
• Medical Safety: KEEP AWAY from pacemakers and sensitive medical implants.
• Electronics: Safe for modern devices at a distance, but avoid direct contact with magnetic storage media.

Applications:

• Concealed magnetic latches for high-end furniture, secret doors, and cabinetry
• Heavy-duty 3D-printed enclosures and removable structural panels
• Secure mounting for retail signage, lightweight lighting, and graphics
• Magnetic couplers for mid-sized robotics and high-torque mechanical prototypes
• High-performance proximity sensors requiring a robust trigger field
