USA: +1 330 486 0001 Singapore: +65 6779 9091 Magnet The hard ferrite magnet consists of a steel casing, which is open towards the adhesive surface and equipped with a barium ferrite magnet (BaFe). The magnetisation already takes place during the shaping and is thus in imposed axial direction (anisotropic). The magnetic clamp disk can be screwed onto a surface through a centre hole with a countersunk screw to save space. For fastening, screw in a M5 countersunk screw made of unmagnetic, non-conducting material, e. g. V2A or brass from the direction of the adhesive surface.
