Neodymium Countersunk Pot Magnet – 12mm Diameter x 5mm Height

The Neodymium Countersunk Pot Magnet – 12mm Diameter x 5mm Height is a compact rare earth mounting magnet designed for secure, low-profile attachment to compatible ferromagnetic steel surfaces. Measuring just 12mm in diameter x 5mm high, this small pot magnet features a countersunk centre hole that allows it to be mechanically fastened using a compatible countersunk screw.

The magnetic assembly incorporates high-performance Neodymium Iron Boron (NdFeB) magnetic material within a protective steel pot or cup. This steel housing helps protect the brittle neodymium magnet while also directing and concentrating magnetic flux towards the active working face.

Its combination of a 12mm diameter, 5mm low-profile height and countersunk mounting hole makes this neodymium pot magnet suitable for compact fixtures, cabinetry, displays, signage, furniture, equipment and OEM assemblies where installation space is limited.

Compact 12mm x 5mm Pot Magnet

At only 12mm in diameter x 5mm high, this countersunk pot magnet is particularly useful where installation space is restricted.

Its small footprint allows magnetic holding or positioning functionality to be incorporated into compact products and assemblies without requiring a large magnetic component.

The low-profile format can also be useful for recessed or concealed installations where the magnet needs to sit close to the mounting surface.

Countersunk Hole for Mechanical Mounting

The centre of the magnet incorporates a countersunk mounting hole, allowing a compatible countersunk-head screw to sit neatly within the magnet's profile.

Mechanical fixing can provide a more permanent and reliable method of securing the magnet to a product or fixture than adhesive-only installation.

Typical mounting surfaces may include:

• Timber
• Plastic components
• Composite materials
• Suitable metal assemblies
• Custom fabricated housings

The exact countersunk hole and compatible screw dimensions have not been supplied, so the required fastener size should be confirmed before installation.

Avoid overtightening the mounting screw, as excessive force can damage the magnet or pot assembly.

Neodymium Rare Earth Magnet

This pot magnet incorporates Neodymium Iron Boron (NdFeB), a high-performance rare earth permanent magnetic material known for producing strong magnetic attraction relative to its size.

This makes neodymium particularly suitable for compact mounting applications where available space is limited.

Because the magnetic field is permanent, the magnet requires no wiring, batteries or external power source.

How Does a Pot Magnet Work?

A pot magnet combines a permanent magnet with a steel housing or cup.

The steel pot helps redirect and concentrate the magnetic field towards the exposed working face. This creates a useful magnetic mounting surface while also providing additional mechanical protection around the neodymium material.

For best holding performance, the active magnetic face should make close, flat contact with a compatible ferromagnetic surface such as iron or steel.

Magnetic Holding Performance

For maximum practical magnetic attraction, the working face should make direct and complete contact with clean, flat and sufficiently thick ferromagnetic steel.

Actual holding performance can vary considerably according to:

• Steel thickness
• Steel composition
• Surface flatness
• Available contact area
• Air gaps
• Paint or protective coatings
• Rust and contamination
• Direction of applied force
• Vibration or movement

No specific pull force or Gauss rating has been supplied for this 12mm x 5mm pot magnet, so magnetic holding capacity should not be inferred from its dimensions alone.

Direct Pull vs Shear Loads

Magnetic holding is generally strongest when force is applied perpendicular to the steel surface in direct pull.

When a magnet is mounted vertically and the attached component pulls downward, it is subjected to a shear or sliding load. Practical holding capacity in this orientation can be significantly lower than direct-pull performance.

For applications involving vibration, movement, overhead positioning or other dynamic forces, appropriate mechanical retention or a secondary safety system may be required.

Please Note

The specific magnetic grade, pull force, Gauss rating and countersunk screw size have not been provided and should not be assumed from the product dimensions.

Neodymium magnets are extremely powerful for their size but are also hard and brittle. Do not drill, cut or machine the magnetic material, and avoid impacts that may chip, crack or fracture the magnet.

When installing the pot magnet, use a correctly sized countersunk fastener and avoid overtightening.

This magnet should not be used for lifting people, hazardous overhead suspension or safety-critical load holding unless the complete assembly has been appropriately engineered, tested and rated.

Keep strong magnets away from children, pacemakers, medical implants, magnetic storage media and sensitive electronic equipment.
