19mm x 25mm x 15cm Magnetic Latch

This strong latch magnet has supplied dimensions of 19mm x 25mm x 15cm, with the 15cm dimension equivalent to 150mm.

Its elongated profile can make it suitable for applications requiring a longer magnetic latch or catch rather than a small point-style cabinet magnet.

Potential installations include:

• Cabinets
• Doors
• Panels
• Enclosures
• Furniture
• Storage equipment
• Workshop fixtures
• Custom-built assemblies

Before installation, confirm that the supplied dimensions are compatible with the available mounting space and intended closure.

How a Magnetic Latch Works

A magnetic latch uses permanent magnetic attraction to help retain a compatible door, panel or closure in position.

When the latch and mating component are correctly aligned, magnetic attraction helps pull the components together and resist unintended opening.

When sufficient opening force is applied, the magnetic connection separates and the door or panel can be opened.

This provides a simple closure mechanism without requiring an electrically powered locking system.

Cabinet and Cupboard Doors

Magnetic latches are commonly used to help keep cabinet and cupboard doors closed.

Potential applications include:

• Kitchen cabinetry
• Storage cupboards
• Workshop cabinets
• Office furniture
• Utility cabinets
• Display cabinets
• Commercial cabinetry
• Custom furniture

The suitability of this latch for a particular door depends on the installation geometry, door size, hinges, alignment and required holding force.

Access Panels and Equipment Enclosures

This magnetic latch may also be suitable for appropriately designed removable or hinged access panels.

Potential uses include:

• Equipment panels
• Service access doors
• Machinery enclosures
• Storage compartments
• Inspection panels
• Custom equipment housings

Magnetic attachment can provide convenient repeated access where a permanent lock or mechanical fastener is not required.

Where accidental opening could create a hazard, use an appropriately rated mechanical latch or secondary retention system.

Magnetic Alignment

Correct alignment is important for magnetic latch performance.

For reliable operation:

• Align the magnetic latch with its mating surface
• Maximise appropriate contact between components
• Avoid unnecessary gaps
• Check that the door closes squarely
• Adjust hinges or mounting position where required
• Test the completed installation before regular use

Poor alignment can significantly reduce practical magnetic holding.

Air Gaps and Surface Contact

Magnetic attraction decreases as the distance between the magnetic component and its mating surface increases.

Potential air gaps can be created by:

• Incorrect alignment
• Recessed mounting
• Paint
• Protective coatings
• Uneven surfaces
• Door movement
• Warped panels
• Mechanical clearance

For best practical performance, install the latch so the intended magnetic surfaces align correctly when the door or panel is closed.

Magnetic Holding Performance

The practical holding performance of a magnetic latch depends on more than the physical size of the product.

Factors can include:

• Magnetic material
• Internal magnetic construction
• Mating component
• Contact area
• Alignment
• Air gap
• Surface condition
• Door geometry
• Hinge resistance
• Mechanical leverage
• Vibration
• Installation orientation

No specific pull force, holding force or magnetic flux density in Gauss has been supplied for this latch and these values should not be inferred from its dimensions or the word “Strong” in the product name.

Direct Pull vs Opening Leverage

A magnetic latch may resist direct separation differently from the force generated when opening a hinged door.

A hinged door creates mechanical leverage, meaning the force experienced at the magnetic latch can vary according to:

• Latch position
• Hinge position
• Door dimensions
• Handle position
• Opening direction
• Alignment

For this reason, a laboratory pull-force value, even where available, would not necessarily represent the practical force required to open an installed cabinet or door.

Test the latch in the actual application before relying on its holding performance.

Replacement Magnetic Latch Applications

This product may be suitable as a replacement magnetic latch where its dimensions and operating characteristics match the existing installation.

Before replacing an existing latch, compare:

• Overall dimensions
• Mounting space
• Alignment
• Mating surface
• Required holding performance
• Door or panel geometry

Do not assume compatibility based solely on the general appearance of the existing latch.

Compatible Magnetic Surfaces

Magnetic attraction requires an appropriate magnetic mating component or ferromagnetic material.

Common ferromagnetic materials include:

• Mild steel
• Iron
• Magnetic steel

Materials that are inherently non-magnetic include:

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

Many stainless steel grades may also be weakly magnetic or non-magnetic.

A magnetic latch used with a timber, plastic or other non-magnetic door generally requires an appropriately designed ferromagnetic mating component as part of the closure system.

Permanent Magnetic Operation

This strong latch magnet uses permanent magnetic attraction.

It requires:

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

The magnetic component remains continuously active during normal use.

This can make magnetic latches a simple solution for applications where an electrically controlled lock is unnecessary.

Magnetic Latch vs Mechanical Lock

A magnetic latch is designed primarily to help retain a compatible door or panel in its closed position.

It should not automatically be treated as equivalent to:

• A security lock
• A keyed lock
• A safety latch
• A load-rated restraint
• A child-safety lock
• An engineered mechanical fastener

Where security, personal safety or load retention is required, use an appropriately rated locking or mechanical retention system.

Installation Considerations

Before installing the latch:

• Confirm the available mounting space
• Verify the supplied dimensions
• Identify the correct mating position
• Ensure the door or panel closes correctly
• Minimise unnecessary air gaps
• Check alignment
• Confirm compatibility with the mounting surface
• Test the completed closure

The specific mounting hole arrangement, fasteners and installation hardware have not been supplied and should not be assumed.

Use mounting hardware appropriate for the actual latch, substrate and application.

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

If the latch is installed in an application where unexpected opening could cause injury, equipment damage or falling objects, use suitable secondary mechanical retention.
