Abstract
A device for measuring the rotation of a rotating element which contains a magnetic encoder which turns with the rotating element and a sensor integrated with a support which is immobilized in terms of rotation. The magnetic encoder is maintained in close proximity to the sensor by the application of magnetic attraction forces between the magnetic encoder and the support, which is produced, at least partially, out of magnetic material.
