3/16" x 3/16" Neodymium Cylinder Magnet – N52 Grade 

Key Features:

• Dimensions: 3/16" diameter × 3/16" height (Approx. 4.76mm × 4.76mm)
• Precision Tolerance: ±0.05mm – Engineered for exact-fit mechanical housing
• Magnet Grade: N52
• Pull Force: Approx. 2.52 lbs 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating for a durable, mirror-like finish
• Magnetization: Axially magnetized (Poles on the flat circular ends)
• Shape: Square Profile Cylinder / Small Rod

Material Description:

Our 3/16" N52 cylinders are designed for maximum flux density in a compact footprint. Unlike thin discs, the 3/16" depth allows for a larger volume of magnetic material, resulting in a magnetic field that extends further from the surface. This makes them ideal for applications where the magnet must act through a gap or non-magnetic material like plastic, glass, or wood.

Handling Advice: These are small but surprisingly powerful. Because of the rod shape, they can easily snap together sideways, which may cause chipping. Always handle with a steady grip and use a sliding motion to separate them from a stack. Keep away from sensitive electronics and magnetic media.

Warnings and Safety Information:

• Choking Hazard: Small size is extremely dangerous for children and pets. Keep strictly in a secure container.
• Pinch Hazard: Strong enough to cause minor skin pinches. Handle with care.
• Medical Safety: KEEP AWAY from pacemakers and other implanted medical devices.
• Brittleness: Neodymium is a ceramic; these will shatter if allowed to slam into each other or hard surfaces.

Applications:

• Precision Hall-effect sensors and magnetic proximity switches
• Miniature robotics, RC parts, and drone assembly
• Small-scale industrial triggers and high-accuracy mechanical joints
• Tabletop gaming (ideal for magnetizing arms and weapons on larger miniatures)
• High-end magnetic puzzles and modular sculptures
