    Self-Aligning Neodymium Disc Paired Magnets

    Align metal parts consistently without using mechanical guides. These magnet pairs automatically center as they pull together, holding components in the same position every time. Often used to align lenses and sensors, they eliminate the need for recalibration. With the highest strength-to-size ratio of any magnet, these deliver powerful pull force even in tight spaces. Also known as Polymagnets®.
    Warning: Maximum pull ratings are based on direct contact with rust-free, unpainted iron surfaces. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.

    Multiposition Neodymium Disc Paired Magnets

    Snap and lock parts at multiple positions. These magnets have more than one fixed alignment. They’re magnetized in a circular pattern with alternating north and south poles, so they snap together at specific increments. Use them in fixtures, inspection stations, and laser-alignment systems to reposition parts without mechanical detents. With the highest strength-to-size ratio of any magnet, these deliver powerful pull force even in tight spaces. Also known as Polymagnets®.
    Warning: Maximum pull ratings are based on direct contact with rust-free, unpainted iron surfaces. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.

    Twist-Release Neodymium Disc Paired Magnets

    Release magnetic holding force with a simple twist. These paired magnets lock together securely and disengage smoothly when rotated, eliminating the need for tools or latches. Use them in modular assemblies, sensor mounts, and quick-change systems where repeatable alignment and easy disassembly are key. With the highest strength-to-size ratio of any magnet, these deliver powerful pull force even in tight spaces. Also known as Polymagnets®.
    Warning: Maximum pull ratings are based on direct contact with rust-free, unpainted iron surfaces. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.
