In order to fully take advantage of the holding force specified, allow a protrusion of approx. 1.5 mm above the installation surface when installing the magnetic system or enlarge the mounting borehole around the holding surface of the magnetic system by 3-4 mm. A socket made of a non-magnetizable material (AI, Ms, Ku) is also favourable. Magnetic core AlNiCo – If only a direct installation in steel is possible, a holding force reserve of 30 percent should be taken into account when selecting the size of the magnetic system.

* You may shorten the system by the dimension KM without reducing the holding force. Tolerances: D ± 0.1 mm, L ± 0.2 mm.

1) The holding forces have been determined on a polished plate made of steel (S235JR according to DIN 10 025) with a thickness of 10 mm by pulling the magnet vertically from the surface (1kg≈10N). A deviation of -10 % (max.) in the stated values is possible in exceptional cases. In general, the value will be exceeded. Small cracks in the magnetic material do not affect the holding force.
