Abstract

A speed sensor having a sensor housing for accommodating a magnetic field sensor element, an adapter for holding the sensor housing and a magnetic encoder. The invention provides for the speed sensor to have a device for length adaptation or air gap adjustment, and for the device to have a clamping mechanism for holding the sensor housing.

Claims

1-10. -10. (canceled)

11. A speed sensor for use with a magnetic encoder, the speed sensor comprising:

a sensor housing for accommodating a magnetic field sensor element;

an adapter for holding the sensor housing; and

a device for length adaptation or air gap adjustment, the device having a clamping mechanism for holding the sensor housing.

12. The speed sensor as claimed in claim 11, wherein the clamping mechanism has a clamping ring which encompasses the sensor housing.

13. The speed sensor as claimed in claim 12, wherein the clamping ring has a cone which interacts with a mating cone in the adapter.

14. The speed sensor as claimed in claim 12, wherein the clamping ring is held in an axially braceable manner on the adapter, in particular by means of a pressure screw.

15. The speed sensor as claimed in claim 14, wherein a pressure screw for holding the clamping ring in an axially braceable manner can be screwed to the adapter.

16. The speed sensor as claimed in claim 11, wherein the sensor housing has an antirotation safeguard.

17. The speed sensor as claimed in claim 16, wherein, for the antirotation safeguard, the sensor housing has at least one flattened portion which interacts with a corresponding mating surface.

18. The speed sensor as claimed in claim 11, wherein the sensor housing has a rib facing the encoder.

19. The speed sensor as claimed in claim 11, wherein the sensor is an active sensor.

20. The speed sensor as claimed in in claim 11, wherein the magnetic field sensor element operates using the magnetoresistive or Hall principle.
