Claim:
1. A sensor device for providing contactless acquisition of a rotation characteristic of rotatable object, comprising: a sensor housing; at least one magnetic-field generator to generate a magnetic field at the location of the rotatable object; at least one magnetic-field sensor to detect a magnetic field generated by eddy currents of the rotatable object and at least one connection element set up to connect the sensor device to a device that includes the rotatable object, so that the magnetic-field generator and the magnetic-field sensor are at least partially disposed together in a sensor section of the sensor housing, and the sensor housing is set apart from the device that includes the rotatable object; wherein the sensor section is in the form of a non-magnetic sleeve; wherein the sensor section is introduce-able into a receptacle in a wall of the device, and a coaxial air gap is situated between the sensor section and a wall of the receptacle in the direction of the longitudinal axis of the sensor section in the introduced state; and wherein the receptacle is a blind hole in the wall of the device.
