Arrangement (7, 1) for contactlessly determining a revolution rate and a direction of rotation of a component, in particular a magnetisable shaft, that rotates during its operation, comprising: a) a component that rotates during its operation that comprises on at least one peripheral region a circumferential structure of web-shaped or tooth-shaped radial protrusions and interposed grooves or tooth gaps; and b) a screw-in sensor device for determining a revolution rate and a direction of rotation of the component, comprising b1) a threaded segment for the positionally fixed arrangement of the sensor device, so that the circumferential structure can be moved past the sensor device, b2) a magnetic field generating device and b3) a magnetic field detecting device; characterized c) in that the magnetic field detecting device comprises at least three magnetic field sensors (6_1, 6_2, 6_3) that are not disposed in alignment along a line, wherein the distance between the magnetic field sensors that are the farthest apart from each other is less than or equal to a width (d_N) of the grooves or tooth gaps; d) in that the sensor device is implemented to record a time for a change of flux for each of the magnetic field sensors separately; and e) in that the arrangement has an analysis unit for analysis of the output signals of the at least three magnetic field sensors (6_1, 6_2, 6_3), which is configured to determine the two magnetic field sensors (6_1, 6_2) that are the farthest apart from each other when viewed in the direction of rotation of the component and to use the measured flux changes of said two magnetic field sensors (6_1, 6_2) to determine a direction of rotation. a) a component that rotates during its operation that comprises on at least one peripheral region a circumferential structure of web-shaped or tooth-shaped radial protrusions and interposed grooves or tooth gaps; and b) a screw-in sensor device for determining a revolution rate and a direction of rotation of the component, comprising b1) a threaded segment for the positionally fixed arrangement of the sensor device, so that the circumferential structure can be moved past the sensor device, b2) a magnetic field generating device and b3) a magnetic field detecting device; characterized b1) a threaded segment for the positionally fixed arrangement of the sensor device, so that the circumferential structure can be moved past the sensor device, b2) a magnetic field generating device and b3) a magnetic field detecting device; c) in that the magnetic field detecting device comprises at least three magnetic field sensors (6_1, 6_2, 6_3) that are not disposed in alignment along a line, wherein the distance between the magnetic field sensors that are the farthest apart from each other is less than or equal to a width (d_N) of the grooves or tooth gaps; d) in that the sensor device is implemented to record a time for a change of flux for each of the magnetic field sensors separately; and e) in that the arrangement has an analysis unit for analysis of the output signals of the at least three magnetic field sensors (6_1, 6_2, 6_3), which is configured to determine the two magnetic field sensors (6_1, 6_2) that are the farthest apart from each other when viewed in the direction of rotation of the component and to use the measured flux changes of said two magnetic field sensors (6_1, 6_2) to determine a direction of rotation.
