Product Description The 20mm x 10mm x 15mm Neodymium Block Magnet is a specialized heavy-duty magnet featuring a unique 15mm thickness. This substantial depth allows for a much deeper magnetic reach compared to flat disc magnets. Each block is manufactured from high-grade N35 neodymium and protected by a Ni-Cu-Ni triple-layer coating, providing a smooth, professional finish and essential resistance to corrosion.

Key Features

  • Massive Magnetic Depth: The 15mm thickness generates a concentrated magnetic field that extends further from the surface.

  • High Pull Force: N35 grade material provides a superior power-to-weight ratio for industrial-strength holding.

  • Durable Protection: Triple nickel plating prevents the brittle core from oxidizing and adds a polished look.

  • Precision Geometry: Clean rectangular edges make it easy to mount into custom milled slots or 3D-printed housings.

  • Axial Alignment: Magnetized through the 15mm thickness, placing the poles on the 20x10mm faces for maximum grip.

Technical Details

  • Material: Sintered Neodymium-Iron-Boron.

  • Max Operating Temp: 80°C.

  • Dimensional Tolerance: ±0.1mm.

Prototyping and Engineering Tips from Robogears

  • Deep-Reach Latching: Because this magnet is 15mm thick, it is perfect for applications where the magnet must act through a thick non-magnetic barrier, such as a wooden tabletop or a thick plastic robot shell.

  • Separation Technique: These magnets are extremely difficult to pull apart directly. Always slide them sideways to break the magnetic bond.

  • Shock Sensitivity: Neodymium is essentially a metallic ceramic. If you allow two blocks to "slam" together, they will likely shatter or chip. Use spacers when storing them together.

  • Glue Selection: For a permanent bond, use a high-strength epoxy. Because the nickel coating is very smooth, it helps to lightly scuff the bonding surface with 400-grit sandpaper first.

Package Includes
