Permanent magnet for magnetic field sensors
The hard ferrite magnet consists of strontium ferrite (SrFe). 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, use a M5 countersunk screw made of unmagnetic, non-conducting material, e. g. V2A or brass. The dimensional tolerance usually amounts to ±0.1 mm
