Material Description:

Our 3/8" x 3/16" N52 discs are designed for professional engineering applications that require a robust magnetic bond with a concentrated footprint. The 3/16" thickness ensures an incredibly deep magnetic field, allowing the flux to penetrate through thicker non-magnetic barriers like heavy cabinetry, industrial resin, or composite housings. These are the premier choice for "invisible" heavy-duty latches, magnetic couplers in robotics, and securing equipment in environments subject to constant movement or vibration.

Handling Advice: DANGER: These magnets possess extreme snap velocity. With over 6 lbs of pull force, they can jump toward each other from several inches away. High-impact collisions WILL shatter the brittle neodymium core and can cause serious skin pinches or blood blisters. Always handle one at a time and separate by sliding horizontally with a firm grip.

Warnings and Safety Information:

• Pinch Hazard: Strong enough to cause blood blisters or painful skin pinches. Handle with caution.
• Choking Hazard: Small size is dangerous for children and pets. Keep strictly secured.
• 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, panels, and high-end cabinetry
• Structural mounting for heavy hand tools, workshop organization, and removable fixtures
• High-torque magnetic couplers for robotics and industrial prototypes
• Precision sensor triggers for high-accuracy Hall effect sensors requiring a deep field
• Secure mounting for outdoor signage and heavy retail displays
