• Surface Gauss: Approx. 4,150 Gauss

Material Description:

Our 3/8" x 1/8" N52 discs are designed for professional applications that require a robust magnetic bond without taking up significant space. The 1/8" thickness ensures a high magnetic volume, allowing the flux to penetrate through non-magnetic barriers like acrylic housings, industrial resin, or heavy cabinetry wood. These are the premier choice for "invisible" heavy-duty latches, magnetic couplers in small-scale robotics, and securing equipment in environments subject to movement or vibration.

Handling Advice: DANGER: These magnets possess high snap velocity. With over 4 lbs of pull force, they can jump toward each other or steel tools from several inches away. High-impact collisions can shatter the brittle neodymium core and cause painful skin pinches. Always handle one at a time and separate by sliding horizontally.

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 high-end furniture, small secret doors, and cabinetry
• Structural mounting for hand tools, workshop organization, and removable jigs
• Magnetic couplers and motor components for professional robotics and prototypes
• Precision sensor triggers for Hall-effect sensors requiring a deep, focused field
• Secure mounting for retail display components and heavy-duty signage
