12mm x 12mm (15/32" x 15/32") Neodymium Cylinder Magnet – N52 Grade 

Key Features:

• Dimensions: 12mm diameter × 12mm thickness (Approx. 15/32" × 15/32")
• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52
• Pull Force: Approx. 16.4 lbs
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating for a durable finish
• Magnetization: Axially magnetized (Poles on the flat circular 12mm ends)
• Shape: Square Profile Cylinder

Material Description:

Our 12x12mm N52 cylinders are designed for maximum flux density. Unlike thin discs, the 12mm depth allows for a much larger volume of magnetic material, resulting in a magnetic field that extends much further from the surface. This makes them ideal for applications where the magnet must act through a gap or thick non-magnetic material (like plastic, glass, or heavy wood panels).

Handling Advice: At over 14 lbs of pull force, these are extremely powerful. They will snap together with violent force from several inches away. Always handle with a firm, steady grip and never leave them near sensitive electronics or credit cards. Use a sliding motion to separate them from a stack.

Warnings and Safety Information:

• Severe Pinch Hazard: Can cause skin tears, bruising, or blood blisters. Handle one at a time with caution.
• Choking Hazard: Keep strictly away from children and pets.
• Medical Safety: KEEP AWAY from pacemakers and other implanted medical devices.
• Brittleness: Neodymium is a ceramic; these will shatter if allowed to slam into each other.

Applications:

• Industrial-grade Hall-effect sensors and magnetic switches
• Magnetic stir bars for high-viscosity laboratory and chemical mixing
• Heavy-duty hidden latches for thick-panel cabinetry and secret doors
• High-torque couplings for DIY robotics and large-scale RC projects
• Precision jigs and fixtures for woodworking and metal fabrication
