Material Description:

Our 38x3mm N52 discs are designed for demanding engineering projects that require a massive magnetic footprint and significant vertical lift. The 1.5-inch diameter provides exceptional resistance to shear forces, making it nearly impossible for the magnet to slide once engaged. At 3mm thick, it produces a deep-reaching magnetic field that can penetrate through heavy non-magnetic materials like thick industrial plastics, structural wood, or composite panels. These are the premier choice for "invisible" heavy-duty latches in high-end cabinetry and securing heavy equipment in high-vibration environments.

Handling Advice: DANGER: These magnets possess immense snap velocity and crushing force. With over 30 lbs of pull force and a wide surface area, they will jump together from several inches away. High-impact collisions WILL shatter the brittle neodymium core and can cause serious injury to fingers, including severe crushing or blood blisters. Always handle one at a time and use non-magnetic spacers when storing.

Warnings and Safety Information:

• Crush Hazard: High risk of serious skin and finger injury. Handle with industrial-strength focus.
• Fragility Hazard: Will shatter upon impact if allowed to snap together. Handle with a firm, steady grip.
• Medical Safety: KEEP AWAY from pacemakers and sensitive medical implants at all times.
• Electronics: Keep well away from hard drives, credit cards, and sensitive electronic testing equipment.

Applications:

• Heavy-duty concealed latches for secret doors, oversized panels, and security safes
• Structural mounting for heavy machinery, tool racks, and industrial fixtures
• High-torque magnetic couplers and rotors for professional robotics or wind turbines
• Magnetic separation systems for removing ferrous contaminants from high-volume bulk materials
• Secure, removable mounting for heavy outdoor signage and architectural graphics
