Abstract

A sensor holder for a piston-cylinder unit with a cylinder and a piston rod which is movable relative to the latter comprises a holding element which carries out a synchronous movement with respect to the piston rod and has a first position measuring device. A second position measuring device is held by a holder so as to be axially stationary with respect to the cylinder, and there is a rotationally oriented installation position between the first position measuring device and second position measuring device. The cylinder-side holder and the holding element are rotatable relative to one another, and a magnetic force acting between the holder and the holding element brings about a rotational orientation of the two position measuring devices relative to one another.
