US Patent 7228642 Probe for a coordinate measuring machine

A probe for a coordinate measuring machine has a stationary first part and a second part which can move relative to said first part. The second part can be a feeler pin or a feeler pin extension of the probe. A damping member for damping vibrations of the moveable second part has a magnet arrangement for producing a magnetic field, and has a conductor element. The magnet arrangement is designed such that there is a change in direction of the magnetic field along a path of movement of the conductor element.
