9.5mm Diameter x 6.35mm Thick Disc Magnet

This neodymium magnet measures 9.5mm in diameter x 6.35mm thick, creating a compact disc-shaped magnetic component.

Its dimensions make it suitable for integration into:

• Circular recesses
• Product housings
• Mechanical assemblies
• Closures
• Sensor systems
• Fixtures
• Models
• Prototype components
• Custom manufactured products

Where the magnet is installed into a recess, provide suitable clearance and avoid force-fitting the brittle neodymium material.

N35 Grade Neodymium Magnet

This magnet is manufactured from N35 grade Neodymium Iron Boron.

The N35 designation describes the magnetic material grade and relates to the material's magnetic properties. It does not mean that every N35 magnet provides the same pull force.

Finished magnetic performance also depends on:

• Magnet dimensions
• Magnet geometry
• Magnetisation direction
• Magnetic circuit
• Target material
• Target thickness
• Contact area
• Air gaps
• Surface condition

For this reason, the N35 grade should not be treated as a pull-force, Gauss or safe-working-load specification.

Neodymium Iron Boron Rare Earth Material

Neodymium Iron Boron (NdFeB) is a high-performance rare earth permanent magnetic material widely used where substantial magnetic performance is required from compact dimensions.

Neodymium magnets are commonly selected for:

• Compact magnetic assemblies
• Sensors
• Electronics
• Closures
• Mechanical equipment
• Fixtures
• Product manufacturing
• Engineering applications

Their high magnetic performance relative to size allows relatively small magnets to be incorporated into applications where larger conventional magnets may be impractical.

Magnetic Closures and Catches

This compact disc magnet can be incorporated into appropriately designed magnetic closure systems.

Potential applications include:

• Cabinet closures
• Boxes
• Product packaging
• Display components
• Access panels
• Furniture
• Small doors and covers
• Custom enclosures

Depending on the design, the magnet may attract a ferromagnetic steel strike plate or another appropriately oriented magnet.

For magnet-to-magnet closures, confirm polarity before permanent installation.

Sensors and Instrumentation

Compact neodymium disc magnets are commonly incorporated into magnetic sensing applications.

Potential uses include:

• Position sensors
• Proximity switches
• Reed switch systems
• Instrumentation
• Detection systems
• Mechanical indicators
• Automation components
• Prototype electronics

The magnetisation direction and pole orientation have not been supplied for this product. These characteristics should be confirmed where magnetic field direction is important to sensor operation.

Fixtures and Positioning

The compact dimensions can also make this N35 magnet useful for positioning components in fixtures and assemblies.

Potential applications include:

• Assembly fixtures
• Positioning guides
• Removable components
• Inspection fixtures
• Prototype tooling
• Small jigs
• Product manufacturing

Where vibration, shock or dynamic movement is present, magnetic holding should be evaluated under actual operating conditions.

Magnetic Performance

The practical magnetic performance of this N35 disc magnet depends on factors including:

• N35 magnetic material
• Magnetisation direction
• Target steel composition
• Target steel thickness
• Available contact area
• Surface flatness
• Air gaps
• Paint and coatings
• Rust and contamination
• Load direction
• Magnetic circuit design

No specific pull force or magnetic flux density in Gauss has been supplied for this product and these values should not be inferred from its N35 grade or physical dimensions.

Direct Pull vs Shear Force

Magnetic holding performance varies according to the direction of the applied load.

Direct pull occurs when the magnet is pulled perpendicular to the target steel surface.

Shear force occurs when the load acts parallel to the target surface and encourages the magnet to slide.

Practical holding on vertical surfaces can therefore be significantly lower than ideal direct-pull performance.

Friction, vibration, leverage and dynamic movement can further affect holding.

Air Gaps and Surface Contact

Neodymium magnets generally perform best when positioned close to compatible ferromagnetic material.

Magnetic attraction can be reduced by:

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

With a compact magnet such as this 9.5mm diameter disc, even relatively small air gaps can have a noticeable effect on practical magnetic performance.

Bonding Neodymium Disc Magnets

This magnet may be bonded into a suitable circular recess or onto an appropriate substrate.

Before bonding:

• Confirm magnetic polarity and orientation
• Ensure surfaces are clean and dry
• Remove oils, grease and contamination
• Select an adhesive compatible with both materials
• Provide suitable dimensional clearance
• Avoid force-fitting
• Allow the adhesive to cure according to its instructions

The surface coating or plating for this magnet has not been supplied, so adhesive compatibility should be verified for the actual product finish.

Compatible Target Materials

Neodymium magnets attract suitable ferromagnetic materials, including:

• Mild steel
• Iron
• Magnetic steel
• Suitable ferromagnetic components

They do not effectively attract non-magnetic materials such as:

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

Many stainless steel grades may be weakly magnetic or non-magnetic and should be tested before relying on magnetic attachment.

Neodymium vs Ferrite Disc Magnets

Neodymium and ferrite are both permanent magnetic materials, but they provide different characteristics.

Neodymium magnets generally provide:

• Higher magnetic performance relative to size
• Strong magnetic properties from compact dimensions
• Advantages where installation space is limited
• Broad use in sensors, electronics and precision assemblies

Ferrite magnets are generally:

• More economical
• Naturally corrosion resistant
• Suitable for many general-purpose magnetic applications
• Used where a physically larger magnet is acceptable

This N35 neodymium disc magnet can be particularly useful where compact dimensions and high magnetic performance relative to size are priorities.

Permanent Magnetic Operation

This N35 neodymium disc magnet is a permanent magnet.

It requires:

• No electricity
• No batteries
• No charging
• No external power supply

Its magnetic field remains continuously active during normal use.

Handling Neodymium Magnets

Neodymium magnets are hard and brittle and should be handled carefully.

Avoid:

• Allowing magnets to snap together
• Allowing the magnet to strike steel objects
• Dropping it onto hard surfaces
• Force-fitting it into an undersized recess
• Drilling
• Cutting
• Machining
• Applying unnecessary impact

Neodymium magnets can chip, crack or break during uncontrolled collisions, and damaged fragments may have sharp edges.

Safety Information

This is a small, powerful permanent magnet and must be kept securely away from babies and children.

Swallowed magnets can cause serious or life-threatening internal injuries. If multiple magnets, or a magnet and another metal object, are swallowed, they can attract through intestinal tissue. Seek urgent medical attention if magnet ingestion is suspected.

Keep neodymium magnets an appropriate distance from:

• Pacemakers
• Implanted medical devices
• Magnetic storage media
• Magnetic cards
• Sensitive electronic equipment

Where unexpected magnetic release could cause injury or equipment damage, use appropriate mechanical retention rather than relying solely on magnetic attraction.
