| description | An apparatus, for determining a relative direction of a movement of an encoder object depending on a magnetic field which is generated or influenced by the encoder object. A magnetic field sensor generates two sensor signals based on the magnetic field, that indicate a profile of the magnetic field in the event of a relative movement between the encoder object and the magnetic field sensor, that fluctuate around a mean value and are phase-shifted 90° to one another. The processing circuit calculates an angle based on the two sensor signals, and determines the relative direction of the movement of the encoder object based on a gradient of the angle between a switch-on time of the apparatus and a threshold value angle which is reached thereafter or based on a gradient of the angle between the situation of two successive threshold value angles being reached. |
