This 12V DC electromagnet is designed for applications requiring a strong, switchable magnetic hold. It's ideal for industrial automation, robotics, and security systems where precise control over magnetic force is needed. A key benefit is its 'energise-to-hold' functionality, allowing for instant magnetic engagement and release. However, it requires a dedicated DC power source, which is not included.

This electromagnet requires a 12V Direct Current (DC) power source. An AC power source is not compatible and could damage the unit.
No, the 12V DC power source is not included and must be purchased separately.
The electromagnet has a maximum possible pull force rating of up to 430kg under ideal conditions.
It is supplied with an M10 threaded hole on the reverse side for easy fixing and mounting to a suitable surface.
The approximately 605mm of wire is used for connecting the electromagnet to a direct current (DC) power source.
This is an 'energise-to-hold' magnet, meaning it only holds when powered. When power is removed, it loses its magnetism. For 'fail-safe' applications where holding is required when power is lost, a 'de-energise-to-hold' magnet would be more appropriate.
'Energise to hold' means the electromagnet becomes magnetic only when it is supplied with electrical current. When the current is switched off, it ceases to be magnetic.
Verify that the 12V DC power supply is correctly connected and providing power. Ensure the current is flowing in the correct direction (polarity). Check that the connected wire is not damaged and that the power source is switched on.
Ensure the surface of the electromagnet and the object being attracted are clean and free from obstructions. Check that the power supply is stable and delivering the full 12V DC and sufficient wattage (33W). Verify the distance between the magnet and the object is minimal.
This is an 'energise-to-hold' magnet; it should have zero magnetic strength when switched off. If residual magnetism is observed, ensure the DC power supply is fully disconnected and try demagnetizing the object if possible. Contact support if the issue persists.
Ensure the electromagnet is operated within its specified 12V DC / 33W rating. Verify that the power source is stable and not fluctuating. Check for any obstructions or continuous load that exceeds the magnet's rated pull force, as this can cause the coil to draw excessive current.
