The stated forces have been determined at room temperature on a plate in polished steel (S235JR according to DIN 10 025) with a thickness of 10 mm (1kg ~ 10N). A maximum deviation of -10% compared to the specified value is possible in exceptional cases. Value is exceeded in general. Depending on the type of application (installation situation, temperatures, counter anchor etc.) the forces can be influenced enormously. The indicated values are serving as an orientation.
ED's is a percentage measure of the connection time. If the magnet is supposed to work shorter period of time (lower ED), you can increase voltage and get more power. Lower voltage gives lower force.
Strength at a distance. In the graph below, we can see how enormously the holding force is affected by distance. From full strength with direct contact on the counter plate/anchor plate, to almost full reduced force with less than 1mm distance.
Magnetic flux. Equally important is having a sufficiently thick iron plate/counter plate for the magnet. Below we can see how the magnetic field passes through the material and is not utilized if the magnet is too powerful for its corresponding anchor material. This 71-1080 model achieves full strength at a 10mm thickness as described in the above graph.
