• Magnetization: Axially magnetized (Poles on the large 20x20mm flat faces)
• Shape: Square Block

Material Description:

Our 20x20x2mm N52 blocks strike an ideal balance between size and strength. The broad 20mm footprint ensures a wide magnetic field and superior adhesive stability, while the 2mm thickness provides the volume needed to generate a deep field that "reaches" through non-magnetic surfaces. These magnets are designed for professional-grade fasteners that need to stay secure under vibration or movement.

Handling Advice: DANGER: At over 10 lbs of pull force, these are strong enough to cause significant skin pinches. They will snap together with violent force from several inches away. Always handle one at a time and use a sliding motion to separate them. Use non-magnetic tools to avoid chipping the brittle neodymium core or scratching the nickel plating.

Warnings and Safety Information:

• Pinch Hazard: Can cause painful skin pinches or blood blisters. Handle with a firm, steady grip.
• Choking Hazard: Keep strictly away from children and pets.
• Medical Safety: KEEP AWAY from pacemakers and sensitive medical implants.
• Brittleness: High-impact collisions will cause shattering. Never let them slam together.

Applications:

• Heavy-duty magnetic latches for cabinetry, hidden doors, and secret panels
• Mounting heavy signage or equipment to ferrous steel structures
• Industrial proximity sensors and robust magnetic triggers
• Precision jigs and fixtures for woodworking and metal fabrication
• Advanced 3D-printed removable panels and heavy-load enclosures
