KM110BH/2430;
KM110BH/2470
30° and 70° angle sensor hybrids
Notes to the characteristics
1. Refer to Fig.3. The magnetic field Hext = 100 kA/m can be achieved using the magnets listed in Table 1.
2. The sensitivity will change slightly with +0.33% per 10% magnetic field increase if Hext deviates from 100 kA/m.
3. Deviation from best straight line in angle range.
4. Difference in output signal (expressed in degrees) between two zero point (α = 0°) measurements, in which the zero
point is approached from the same side of the measuring range (e.g. cycle: +15°
5. The smallest detectable change of angle ∆α for α = 0° (cycle: 0° ∆α).
6. As note 4, but with the zero point being approached from the upper end and lower end of the measuring range
