5mm x 5mm x 2mm Neodymium Square Block – N52 Grade 

Key Features:

• Dimensions: 5mm Length × 5mm Width × 2mm Thickness
• Precision Tolerance: ±0.05mm 
• Magnet Grade: N52 
• Pull Force: Approx. 1.5 lbs 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating 
• Magnetization: Axially magnetized through the 2mm thickness (Poles on the 5x5mm faces)
• Shape: Square Micro-Block

Material Description:

Our 5x5x2mm N52 blocks offer a perfect balance of a compact footprint and substantial magnetic depth. The 2mm thickness allows the magnetic field to penetrate through thicker non-magnetic barriers compared to ultra-thin strips. The square geometry ensures the magnet remains perfectly aligned and resists rotation, making it the ideal choice for high-torque micro-couplings and precision industrial sensors.

Handling Advice: At nearly 1.5 lbs of pull force, these small magnets are surprisingly strong. They will snap together with force, which can cause the brittle neodymium core to chip. Always separate them by sliding the top magnet off the stack horizontally rather than lifting, and use non-magnetic tools for placement.

Warnings and Safety Information:

• Choking Hazard: Small size is extremely dangerous for children and pets. Keep strictly in a secure container.
• Pinch Hazard: Strong enough to cause minor skin pinches. Handle with a steady grip.
• 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:

• Heavy-duty proximity sensors and robust magnetic triggers
• Precision 3D-printed latches for small electronics and enclosures
• High-performance articulation for gaming miniatures and scale models
• Modular mounting systems for lightweight tools and micro-organization
• Bespoke jewelry box latches where a narrow, strong hold is required
