Abstract
The invention concerns arrangements for detecting a rotational or translatory movement between a signal-generating element having a symmetrical magnetic field and means for detecting the magnetic field of the signal-generating element. According to the invention, an analogue, magnet-sensitive sensor element is aligned such that the normal vector of the sensitive surface of the sensor element forms an angle to a vector pointing vertically from the sensor element perpendicularly to the axis of the signal-generating element. The sensor element generates signal pulses whose shapes between their edges are dependent on the direction of movement and rise or fall, such that, when the direction of movement is reversed, the sign of the signal shape changes. The invention proposes simple arrangements for detecting a rotational or translatory movement which requires only one sensor element yet has high resolution.
