Product Information

Full details

This powerful 12V DC electromagnet is designed for automated systems requiring secure, electrically controlled holding. It offers a substantial pull force of up to 454kg, ideal for machinery doors, access control, and material handling. A key caveat is that it requires a separate DC power source and wiring. Its key features include an 'energise-to-hold' mechanism, robust construction for industrial use, and easy mounting options.

FAQs

What is the maximum weight this electromagnet can hold?

The electromagnet has a maximum possible pull force rating of up to 454kg. Actual holding force may vary based on the condition of the mating surface and environmental factors.

Does the power supply come included with the electromagnet?

No, the 12V DC power source is not included. You will need to provide a suitable 12V DC power supply rated for at least 7.8W.

How do I mount the electromagnet?

The electromagnet is supplied with two 6mm mounting holes on the reverse side for easy fixing and mounting to a suitable surface.

What does 'energise to hold' mean?

'Energise to hold' means the electromagnet becomes magnetic only when it is supplied with electrical current. When the current is switched off, its magnetic field disappears.

Can this electromagnet be used outdoors?

This electromagnet is designed for industrial applications. It is not explicitly rated for outdoor use and should be protected from moisture and extreme environmental conditions.

How long is the wire supplied with the magnet?

The electromagnet is supplied with approximately 610mm of wire for connecting to a direct current power source.

What materials can this electromagnet attract?

This electromagnet is designed to attract ferrous materials, such as iron and steel.

Troubleshooting

Magnet does not attract any metal

Verify that the 12V DC power supply is correctly connected and switched on. Check polarity and ensure the power source is adequate for the 7.8W requirement.

Weak holding force

Ensure the surface of the electromagnet and the mating ferrous object are clean, flat, and free from rust or paint. Check for sufficient power supply.

Magnet remains slightly magnetic after power is off

This could indicate residual magnetism. Ensure the power is completely cut off. If persistent, the core material might be exhibiting minor remanence; ensure the application allows for this possibility or consider a different type of magnet if zero residual magnetism is critical.

Overheating during operation

Confirm the power supply is stable and not exceeding the magnet's continuous duty rating. Reduce the duration of continuous 'on' cycles or ensure adequate ventilation.

Pros and Cons

Pros

  • Extremely strong holding force (up to 454kg).
  • Reliable electrical control for automated operations.
  • Versatile applications in industrial automation, security, and material handling.
  • Simple to install with pre-drilled mounting holes.
  • Zero residual magnetism when de-energized.

Cons

  • Requires a separate 12V DC power supply (not included).
  • Requires knowledge of electrical wiring for safe operation.
  • Not suitable for continuous duty cycles without proper heat management considerations.
  • Limited to ferrous material handling due to magnetic nature.

Setup, Compatibility & Care

Setup:

  1. Mounting: Secure the electromagnet using the two 6mm mounting holes on its reverse side to the desired surface.
  2. Wiring: Connect the approximate 610mm of wire to a stable 12V DC power source. Ensure correct polarity.
  3. Power Source: A compatible 12V DC power supply capable of delivering at least 7.8W (or a higher amperage rating to handle the initial current draw) is required. This is not included.

Compatibility:

  • Operates with any stable 12V DC power source.
  • Effective on ferrous metals (iron, steel).
  • Ensure the mating surface is clean and flat for maximum holding force.

Care:

  • Keep the electromagnet's face clean and free from debris to maintain optimal performance.
  • Avoid exposing the unit to excessive moisture or corrosive environments.
  • Periodically check wiring connections for security and wear.
  • Ensure the power supply is adequate and stable.
