Zusammenfassung:The present invention relates to a displacement sensor for contactless measurement of a relative position of a magnetic field source, which generates a magnetic field, and a magnetic field sensor arrangement with respect to each other. The present invention also further relates to a corresponding production method for producing such a magnetic field sensor arrangement and to an associated magnetic field sensor. The magnetic field sensor arrangement (106) comprises a first magnetic field sensor (108) for generating a first position signal and at least one second magnetic field sensor (110) for generating a second position signal. Each of the magnetic field sensors (108, 110) comprises at least one magnetic field probe (118) for detecting a magnetic flux density of the magnetic field, an evaluation unit for evaluating an output signal of the magnetic field probe, and a communication interface for emitting and receiving communication signals, wherein the first and the second magnetic field sensor are connected to each other via a data bus (112) for transmitting said communication signals, wherein the first magnetic field sensor and the at least one second magnetic field sensor are connected to each other via a leadframe (140) and wherein the magnetic field sensor arrangement has a housing (138) which encloses all the magnetic field sensors (108, 110).
