The invention relates to a sensor arrangement, for example for determining the position and/or motion of an element or part which has at least one sensor unit and an electronic supply and receiving unit, the two units being accommodated in housings which are independent of one another, characterized in that the energy for operating at least one sensor unit (3, 3′) is transmitted between the housings (5 and 6) by magnetic induction, the housing (6) of the supply and receiving unit (4) containing a primary coil (7) which is electrically connected to the latter, the housing (5) of at least one sensor unit (3, 3′) containing a secondary coil (8) which is electrically connected to the latter, of a thus jointly formed transformer (7 and 8), and that the sensor states are transmitted by means of wireless transmission to the supply and receiving unit (4).
