With the spacers, the field strength is reduced to 50mT or 25mT (see Table 7). Table 7: Setting of the Air Gap Spacer Thickness (mm) Air Gap (mm) Magnetic Field (mT) None 1.5 75 0.7 2.2 50 2 3.5 25 Figure 15: Air Gap Setting MAGNET SUPPLIERS The table below shows a non -exhaustive list of possible magnet suppliers. The magnetization direction must be chosen wisely given the fact that most magnets sold are often axially magnetized, which is not a magnetization direction usually required in magnetic angle sensing applications . Angle sensing applications usually use diametrically magnetized magnets. Table 8: Magnet Suppliers Company Website Address Maurer Magnetics AG www.maurermagnetic.ch Industriestrasse 8
