Separator Bar Tube Magnet – 25mm x 100mm | M6 Thread | N35UH | High Temperature

The Separator Bar Tube Magnet – 25mm x 100mm | M6 Thread | N35UH | High Temperature is a compact high-temperature magnetic separator bar designed to capture magnetically susceptible iron and steel contamination from powders, granules and other compatible free-flowing materials. Measuring 25mm in diameter x 100mm long, this permanent magnetic separator features N35UH grade neodymium magnets and an M6 threaded mounting connection for integration into compatible processing equipment.

The N35UH high-temperature neodymium grade distinguishes this separator tube from standard neodymium magnetic separators. UH-grade neodymium is engineered to provide improved resistance to magnetic performance loss at elevated temperatures, making this tube magnet suitable for compatible processing environments where increased operating temperatures may be encountered.

Also known as a magnetic separator rod, magnetic filter bar, magnetic tube or magnetic separation bar, this compact 100mm separator can be installed individually or combined with additional tubes to create custom magnetic grate and grid assemblies for industrial ferrous contamination control.

N35UH High-Temperature Neodymium Grade

This separator tube incorporates N35UH Neodymium Iron Boron (NdFeB) magnetic material.

The N35 designation identifies the neodymium magnetic grade, while the UH designation indicates a high-temperature neodymium material designed for improved magnetic stability at elevated operating temperatures compared with conventional neodymium grades.

This makes N35UH particularly useful for magnetic separation equipment operating in environments where increased process temperatures may otherwise affect standard neodymium magnets.

A specific maximum operating temperature has not been supplied for this product and should therefore be confirmed before use in a particular high-temperature application.

How Does a Magnetic Separator Bar Work?

As powders, granules or other compatible materials pass around the magnetic tube, magnetically susceptible iron and steel particles are attracted towards the magnetic surface and retained for removal.

Potential contaminants can include:

• Iron particles
• Steel fragments
• Ferrous swarf
• Rust particles
• Small magnetic fasteners
• Other magnetically susceptible contamination

The collected material remains on the separator tube until it is removed during routine cleaning.

Magnetic attraction decreases rapidly with distance, so effective separator design should encourage processed material to pass sufficiently close to the magnetic surface.

Compact 100mm Separator Bar

With a 100mm overall length, this tube magnet is particularly useful where installation space or product-flow width is limited.

Potential applications include:

• Compact hoppers
• Small processing chutes
• Narrow product flows
• Custom processing machinery
• Laboratory or small-scale equipment
• Multi-bar magnetic separator assemblies

Multiple 100mm separator tubes can also be incorporated into an appropriately designed frame where additional magnetic collection surfaces are required.

M6 Thread for Equipment Integration

The M6 threaded mounting connection provides a practical interface for incorporating the separator bar into compatible processing equipment, separator frames and custom magnetic assemblies.

Potential installations include:

• Hoppers
• Chutes
• Magnetic grates
• Separator frames
• Product inlets
• Processing machinery
• Custom fabricated systems

Confirm compatibility with the mating M6 thread and associated mounting hardware before installation.

High-Temperature Magnetic Separation

Temperature can have a significant effect on permanent magnet performance. Excessive heat can temporarily reduce magnetic output and, if the material's limits are exceeded, may cause irreversible loss of magnetic performance.

The N35UH grade is designed to provide greater resistance to elevated-temperature conditions than many standard neodymium grades, making it useful for processing applications where additional thermal performance is required.

Actual suitability will depend on factors including:

• Operating temperature
• Duration of temperature exposure
• Temperature cycling
• Separator construction
• Installation environment
• External magnetic fields
• Process conditions

For critical high-temperature applications, the complete operating conditions should be evaluated before installation.

Magnetic Grate and Multi-Bar Applications

Multiple separator tubes can be arranged within a compatible frame to form a magnetic grate or grid separator.

This configuration places several magnetic collection surfaces across the material flow, increasing opportunities for magnetically susceptible contamination to pass close enough to a magnetic surface to be captured.

Effective system design should consider:

• Number of separator bars
• Bar spacing
• Product flow rate
• Material characteristics
• Product depth
• Contaminant size and shape
• Installation geometry
• Distance from the magnetic surfaces
• Cleaning access

Industrial Ferrous Contamination Control

High-temperature magnetic separator bars can be useful in processing environments where both ferrous contamination control and elevated-temperature resistance are required.

Potential industries and processes include:

• Food and ingredient manufacturing
• Pharmaceutical production
• Plastics processing
• Chemical manufacturing
• Powder processing
• Bulk material handling
• Industrial manufacturing
• Heated processing systems

Depending on the installation, the separator can help capture unwanted ferrous particles before they reach downstream machinery or later stages of production.

Factors Affecting Magnetic Separation Performance

Actual magnetic separation performance depends on more than the magnetic grade alone.

Important factors include:

• Contaminant size and shape
• Magnetic susceptibility
• Product characteristics
• Material flow rate
• Distance from the magnetic surface
• Separator positioning
• Installation geometry
• Operating temperature
• Amount of accumulated contamination

No specific Gauss rating or pull force has been supplied for this separator bar, so magnetic field strength or holding capacity should not be inferred from the N35UH grade.

Cleaning and Maintenance

Captured ferrous contamination should be removed regularly to maintain effective magnetic separation.

During routine cleaning and inspection:

• Follow applicable equipment isolation procedures
• Carefully remove accumulated ferrous material
• Avoid damaging the tube surface
• Inspect the separator for wear or physical damage
• Check the M6 mounting connection
• Ensure magnetic surfaces remain clean
• Confirm the separator is correctly installed before restarting equipment

If the separator operates at elevated temperatures, allow components to cool appropriately before handling where required.

Please Note

This separator bar is designed to capture magnetically susceptible ferrous contamination, including iron and compatible steel. Aluminium, copper, brass, plastic and many stainless steel grades will not be effectively captured.

The N35UH magnetic grade is designed for improved high-temperature performance, but a specific maximum operating temperature has not been supplied for this product. Confirm the appropriate temperature limit before use in any critical or high-temperature process.

No specific Gauss rating or pull-force value has been provided and these specifications should not be assumed.

Where the separator is intended for food, pharmaceutical or other regulated processing applications, confirm that the complete product specification, materials, construction, installation and cleaning procedures meet the requirements of the intended process.

Strong magnetic fields may affect pacemakers, medical implants, magnetic storage media and sensitive electronic equipment.
