Neodymium Iron Boron Rare Earth Magnet

This magnetic assembly uses Neodymium Iron Boron (NdFeB), a high-performance rare earth permanent magnetic material.

Neodymium is widely used where substantial magnetic performance is required from relatively compact dimensions.

Potential benefits of NdFeB magnetic material include:

• High magnetic performance relative to size
• Compact magnetic assemblies
• Suitability for space-restricted designs
• Permanent magnetic operation
• No electrical power requirement

The specific neodymium grade has not been supplied and should not be assumed.

Rectangular Pot Magnet Construction

Unlike an exposed standalone block magnet, this product uses a pot-style magnetic construction.

The surrounding housing forms part of the magnetic circuit and helps direct and concentrate magnetic flux toward the primary working face.

This configuration can make pot magnets particularly useful for magnetic holding, mounting and positioning applications involving suitable ferromagnetic steel.

The housing also provides a practical structure for incorporating mechanical mounting points.

The specific housing material and surface finish have not been supplied and should not be assumed.

Countersunk Mounting Holes

This rectangular pot magnet features countersunk mounting holes, allowing it to be mechanically attached using compatible countersunk fasteners.

Countersunk mounting can help create a low-profile installation by allowing an appropriately selected screw head to sit within the countersunk recess.

Potential mounting surfaces include:

• Timber
• Plastic
• Composite panels
• Equipment housings
• Furniture
• Fixtures
• Fabricated assemblies

The number of countersunk holes, hole diameters and compatible screw sizes have not been supplied, so appropriate fasteners should be selected according to the actual product dimensions and installation requirements.

Installing Countersunk Pot Magnets

When installing the magnet:

• Use correctly sized countersunk fasteners
• Ensure the mounting surface is stable
• Align the magnet before tightening
• Tighten fasteners evenly
• Avoid excessive torque
• Do not overtighten the screws
• Ensure the magnet sits flat without mechanical distortion
• Confirm adequate clearance around the assembly

Neodymium magnetic material is hard and brittle. Excessive tightening or mechanical stress around mounting points may damage the magnetic components.

Low-Profile 5mm Design

With a height of only 5mm, this rectangular magnetic assembly is particularly suitable for applications where protrusion needs to be minimised.

Potential uses include:

• Shallow recesses
• Slim panels
• Display systems
• Cabinetry
• Furniture
• Product housings
• Equipment
• Custom fixtures

The 120mm length also allows the magnetic assembly to extend across a relatively wide section while retaining its narrow 13.5mm width.

Magnetic Holding and Positioning

This rectangular neodymium pot magnet can be used as part of a magnetic holding or positioning system involving compatible ferromagnetic steel.

Potential functions include:

• Holding removable panels
• Positioning components
• Securing displays
• Creating removable fixtures
• Retaining covers
• Locating parts
• Creating magnetic closures
• Mounting accessories to steel structures

Actual holding performance depends on the complete installation rather than magnet dimensions alone.

Signage and Display Applications

The long, slim profile can be useful for commercial display and signage applications.

Potential uses include:

• Removable signage
• Retail displays
• Exhibition displays
• Point-of-sale equipment
• Shopfitting
• Display panels
• Promotional fixtures
• Magnetic presentation systems

The countersunk holes allow the magnet to be mechanically incorporated into the display component while the magnetic working face attaches to suitable steel.

Furniture, Cabinetry and Panels

This rectangular pot magnet may also be integrated into furniture and cabinetry.

Potential applications include:

• Removable access panels
• Cabinet components
• Furniture panels
• Inspection covers
• Decorative panels
• Magnetic closures
• Removable trim
• Equipment enclosures

Where unexpected release could cause injury or property damage, magnetic attraction should be supplemented with suitable mechanical retention.

Fixtures and Jigs

Rectangular pot magnets can provide convenient magnetic positioning in suitable manufacturing and workshop applications.

Potential uses include:

• Assembly fixtures
• Positioning aids
• Temporary guides
• Inspection fixtures
• Removable stops
• Prototype tooling
• Custom jigs

Magnetic attraction can allow components to be positioned against compatible steel without requiring permanent modification of the steel target surface.

Magnetic Performance

Actual magnetic holding performance depends on factors including:

• Neodymium magnetic grade
• Target steel composition
• Target steel thickness
• Available contact area
• Surface flatness
• Air gaps
• Paint and coatings
• Magnet orientation
• Load direction
• Mechanical leverage
• Vibration and shock

No specific pull force or magnetic flux density in Gauss has been supplied for this product and these values should not be inferred solely from its dimensions.

Direct Pull vs Shear Force

Pot magnets generally provide their best practical holding when the working face has close contact with suitable ferromagnetic steel and the load acts in direct pull.

Direct pull occurs when force attempts to separate the magnet perpendicular to the target surface.

When mounted vertically, the magnet may instead experience shear force, which encourages the magnetic assembly to slide along the steel surface.

Practical vertical holding can therefore be considerably lower than an ideal direct-pull result.

Vibration, shock and leverage can reduce holding performance further.

Air Gaps and Surface Coatings

Even small non-magnetic gaps between the magnetic working face and target steel can reduce attraction.

Air gaps may be created by:

• Paint
• Powder coating
• Plastic
• Adhesive
• Protective films
• Dirt
• Rust
• Uneven surfaces

For maximum practical magnetic performance, the working face should generally be positioned as close as possible to clean, flat, compatible ferromagnetic steel.

Compatible Target Materials

This neodymium pot magnet is designed to attract ferromagnetic iron and compatible steels.

Suitable target materials may include:

• Mild steel
• Iron
• Magnetic steel
• Compatible steel structures
• Ferromagnetic machinery components

It will not effectively attract non-magnetic materials such as:

• Aluminium
• Copper
• Brass
• Plastic
• Timber
• Glass

Many stainless steel grades may also provide weak or negligible magnetic attraction and should be tested before use.

Permanent Magnetic Operation

This rectangular pot magnet uses a permanent neodymium magnetic system.

It requires:

• No electricity
• No batteries
• No charging
• No external power source

The magnetic field remains continuously active during normal use.

Handling Neodymium Pot Magnets

Neodymium magnetic material provides high magnetic performance but is also hard and brittle.

Care should be taken during handling and installation.

Avoid:

• Allowing strong magnets to collide
• Dropping the assembly onto hard surfaces
• Overtightening countersunk fasteners
• Applying unnecessary bending or twisting force
• Drilling or machining the magnetic components
• Exposing the magnet to uncontrolled mechanical impact

Strong magnetic attraction can cause the assembly to move suddenly toward nearby steel or other magnets, creating pinch and impact hazards.

Safety Information

Keep strong neodymium magnets away from babies and children.

Care should also be taken around:

• Pacemakers and implanted medical devices
• Magnetic storage media
• Magnetic cards
• Sensitive electronics
• Other strong magnets
• Large ferromagnetic objects

When bringing the magnet toward a steel surface, maintain controlled handling and keep fingers away from potential pinch points.

Please Note

This product is a Neodymium Rectangular Pot Magnet with Countersunk Holes measuring 120mm long x 13.5mm wide x 5mm high.

The pot-style construction helps direct and concentrate magnetic flux toward the primary working face, while the countersunk mounting holes allow mechanical installation using appropriately selected countersunk fasteners.

No specific neodymium grade, pull force, Gauss rating, housing material, coating or finish, countersunk hole diameter, screw size, dimensional tolerance or maximum operating temperature has been supplied and these specifications should not be assumed.

Actual holding performance depends on target steel composition and thickness, contact area, air gaps, surface condition, loading direction, leverage, vibration and the complete magnetic circuit.

Avoid overtightening mounting screws, as excessive mechanical stress can damage brittle neodymium magnetic components.

This product is not certified lifting equipment and should not be used for overhead or safety-critical lifting. Where unexpected magnetic release could cause injury or damage, incorporate appropriate secondary mechanical retention.
