Product Information

Full details

This 12V DC electromagnet is designed for industrial and automation applications requiring controlled lifting and holding of ferrous materials. Its key benefit is the instant magnetic field generation when powered and immediate deactivation when power is removed, offering precise control. A primary caveat is that it requires an external DC power source, which is not included. Key features include a robust 300kg safe working limit, a compact size, and integrated mounting options.

FAQs

What type of power source is required?

A stable 12V DC power source is required. The power supply must be capable of delivering at least 8W.

Is the power supply included with the electromagnet?

No, the power source is not included and must be purchased separately.

What is the maximum weight this electromagnet can hold?

The safe working limit (SWL) is up to 300kg in a vertical direct position when electricity is applied.

How do I mount the electromagnet?

It features a 6mm mounting hole on the reverse side, allowing it to be easily fixed to machinery or a surface using a bolt or screw.

Can this electromagnet be used with AC power?

No, this electromagnet is designed exclusively for direct current (DC) and will not function with AC power. Using AC power can damage the unit.

What materials can this electromagnet hold?

It can hold any ferrous materials, such as iron and steel. It will not attract or hold non-ferrous materials like aluminum, copper, or plastic.

How long is the supplied wire?

Each magnet is supplied with approximately 635mm of wire for connecting to the DC power source.

Troubleshooting

Electromagnet does not activate (no magnetic field)

Verify that the 12V DC power source is connected correctly and is live. Check the wire connections to the electromagnet and the power supply for secure contact. Ensure the power supply is providing the correct voltage and sufficient current (at least 8W).

Weak magnetic holding force

Ensure the electromagnet is clean and free of debris. Check that the surface of the object being held is also clean and flat. Verify that the object is made of a ferrous material. Ensure the power supply is stable and providing the full 12V DC at the required wattage.

Electromagnet remains magnetized after power is cut

This is uncommon for this type of electromagnet. If residual magnetism is suspected, ensure the DC power supply is completely disconnected and there are no other strong magnetic fields nearby. The design is intended for instant deactivation.

Overheating during operation

Confirm the electromagnet is being used within its specified 8W rating. If the application requires continuous holding, ensure adequate ventilation. If it is a short-duration application, prolonged use may exceed design parameters. Check that the power supply is stable and not causing voltage drops under load.

Pros and Cons

Pros

  • Provides instant and strong magnetic force when powered.
  • Magnetic field disappears immediately upon power removal, allowing for precise control.
  • High safe working limit of 300kg for demanding applications.
  • Compact design facilitates integration into existing systems.
  • Easy to mount and connect with pre-attached wiring.

Cons

  • Requires an external 12V DC power source, which is sold separately.
  • Only suitable for lifting and holding ferrous materials.
  • Continuous power is needed to maintain the magnetic hold.
  • Performance can be affected by surface conditions and material properties.

Setup, Compatibility & Care

Setup:

  1. Mounting: Secure the electromagnet using the 6mm mounting hole on its reverse side to your desired fixture or machinery.
  2. Wiring: Connect the supplied wire to a suitable 12V DC power source. Ensure the polarity is correct for activation.
  3. Power Supply: Connect the electromagnet to a regulated 12V DC power supply capable of providing at least 8W (e.g., a 12V DC adapter with sufficient amperage).

Compatibility:

  • Power: Requires a stable 12V DC power source. Not compatible with AC power or other DC voltages.
  • Material: Only effective on ferrous materials (iron, steel, nickel, cobalt).
  • Environment: Suitable for dry, industrial environments. Avoid exposure to excessive moisture or corrosive substances.

Care:

  • Cleaning: Wipe the surface with a clean, dry cloth. For stubborn dirt, use a slightly damp cloth, ensuring no moisture enters the internal components. Allow to dry completely before powering.
  • Inspection: Periodically check the wiring for any signs of damage and ensure the mounting is secure.
  • Operation: Avoid continuous operation at maximum load for extended periods unless the application specifically requires it and thermal management is considered.
