The Controlock® and the testing device

Frequently asked questions

FAQ

What is unique about McNetiq?

Any actual magnetic force compared to a magnet's maximum force is influenced by local circumstances, like steel thickness or the presence of air gaps (uneven surfaces, paints and coatings). When using magnets for safety or engineering then you need to confirm the magnetic force, and compare this to the required minimum. McNetiq is unique in the world by supplying magnetic solutions based on patented Controlock ® technology. This allows a local determining of the actual magnetic force on the location of use. The passionate team has a vast experience of delivering magnetic solutions since 2013.

How do you measure the capacity of the magnet?

Measuring the magnet's capacity can be done by using the Controlock ® measuring testers set to determine the pull force or the shear (sliding) force.

Why is Controlock® a safe system?

The McNetiq magnetic anchor with Controlock® technology is the first (and only) magnetic anchor with force measurement on the location of use. This technology provides 100% assurance of the magnet anchor's exact capacity, before connecting to the final load or safety system. By pressing just one button, the user knows the maximum load of the assembled anchor point. Moreover, the anchor magnets are patented, fireproof, and not dependent on a power source. All these factors -and many more- make this technology safe.

What happens to the magnet when the power is down?

The magnets are power independent. Therefore, there are no implications in case of any power failure.

What is the carrying capacity of the magnets that are used?

McNetiq uses permanent magnets to avoid a dependency on electric power. Both permanent and electro-permanent magnets have 100 kilograms of breakout force per kilogram of their weight. In other words: the load capacity of 1 kilogram of a magnet is 100 kilograms. However, depending on the factors that influence the magnetic force, some magnets have a load capacity of 170 kilograms per kilogram of weight. The actual capacity can be influenced by local circumstances. Typically McNetiq supplies magnets up to 19kg (~42lbs) of weight to comply with most European standards and recommendations. Magnets can be coupled, larger magnets can be supplied if mechanical handling is preferred, or lighter magnets can be supplied.

How do you turn the magnetic force on and off?

Activating the McNetiq magnet can only be done by using the special socket wrench. The wrench should be turned until the magnet snaps into the locked position, which is marked "on". This is a rotation of just under half a turn. The magnetic force is now activated. Turning the magnet off is done by reversing the mechanism using the same special socket wrench until you reach the position that is marked "off".

Why do you need to measure the magnet on every anchoring spot?

The magnet's measurement on every anchoring spot is crucial because the magnet's capacity varies. The attraction capacity depends on the air gap, the thickness of the steel wall, the type of steel, the size of the contact surface, and the weather temperature.

Will lightning strikes affect the magnet?

Even in a worst-case scenario, if one anchor point would carry the full lightning current of 40 kA. No demagnetization of the Neodymium magnets in the anchor point is to be expected. Please, see the document 'the influence of lightning on a magnetic anchor point' under Knowledge, or contact McNetiq to receive more information.

Does the magnetic force of a magnet weaken over time?

Under normal circumstances, neodymium and ferrite magnets, as well as magnetic tapes and sheets, retain their magnetism almost indefinitely. Factors such as more extreme temperature, vibrations, or magnetic fields can, however, might harm the adhesive force of a magnet.

Does the size of the magnet affect its strength?

The attraction strength is affected by the magnet size and the materials from which the magnet is made.

Does the magnet affect other electronics? And how about pacemakers?

Magnets could affect the functioning of pacemakers and implanted heart defibrillators.
A pacemaker could switch into test mode and cause illness.
A heart defibrillator may stop working. A heart defibrillator may stop working.

Are the magnets certified?

McNetiq magnets are certified by Dekra, Lloyd's Register Statement, the Influence of lightning on a magnetic anchor point, Lloyd's Register Safety Review, Coating Advise Nederland, and R-LAB Laboratory.
