5mm x 4mm (13/64" x 5/32") Neodymium Cylinder Magnet – N52 Grade 

Key Features:

• Dimensions: 5mm diameter × 4mm thickness (Approx. 13/64" × 5/32")
• Magnet Grade: N52 
• Pull Force: Approx. 2.15 lbs (Exceptional vertical holding power)
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating for a professional, corrosion-resistant finish
• Magnetization: Axially magnetized (Poles on the flat circular ends)
• Shape: Cylinder / Deep Disc

Material Description:

Our 5x4mm N52 cylinders are designed for high-performance applications that require a small footprint but a massive hold. Because of their 4mm depth, they project a magnetic field much further than a standard disc, making them ideal for triggering sensors through thick plastic or wood. They are the strongest magnets available for this specific 5mm diameter.

Handling Note: The N52 pull force at this thickness is substantial. Neodymium is brittle; avoid letting these magnets snap together from a distance, as they can shatter upon impact. Always slide them apart to maintain the integrity of the coating.

Warnings and Safety Information:

• Choking Hazard: Small size is dangerous for children and pets. Keep strictly in a secure, labeled container.
• Pinch Hazard: Strong enough to cause a painful skin pinch. Handle with steady hands and focus.
• Medical Safety: Keep away from pacemakers and other sensitive medical implants.
• Electronics: Avoid direct contact with magnetic storage media, credit cards, and mechanical watches.

Applications:

• Heavy-duty miniature articulation (ideal for large resin models or wing mounts)
• Industrial proximity sensors and magnetic switches
• Custom magnetic tool organization and jigs for workshops
• Advanced 3D printing (perfect for deep-set friction-fit holes)
• Scientific research and physics laboratory demonstrations
