    When your application calls for heat and corrosion resistance, these compact magnets deliver. They won’t melt, deform, or lose magnetic strength in temperatures up to 570° F. Plus, they stand up to moisture and mild chemicals. They’re often used in high-temperature environments with corrosive liquids, such as for sensors and rotary encoders in drill systems. Also known as rare earth magnets.
    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.

    Magnetized Through Thickness—Magnetized from one flat face to the other, these magnets deliver a concentrated magnetic force. They’re best for direct contact with flat surfaces.

    Keep these compact magnets safe and sound in temperatures up to 390° F. A built-in case shields them from cracks and chips caused by drops and bumps. All stand up to moisture and mild chemicals.
    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.
    Nickel-Plated Iron Case—Concentrates and focuses the magnetic field to maximize holding strength. The nickel-plated finish adds a layer for corrosion resistance. However, the plating may wear off over time.
    Brass Case—Concentrates and focuses the magnetic field to maximize holding strength. Softer than other metals, brass is less likely to scratch or damage surrounding components.
    Zinc-Plated Steel Case—Withstands occasional exposure to moisture.
    Knurled Surface—Get the best possible grip.
    Magnetized Through Thickness—Magnetized from one flat face to the other, these magnets deliver a concentrated magnetic force. They’re best for direct contact with flat surfaces.
    Magnetized Through Diameter—Magnetized outward from the center, these magnets generate a circular magnetic field. This makes them best for sensors and motors where rotational symmetry and precise angles are key.
