PROBLEM TO BE SOLVED: To provide an electromagnetic actuator and especially a small and compact hydropneumatic vibration-proof supporting device containing an electromagnetic actuator. SOLUTION: This electromagnetic actuator is controlled by an electronic control circuit 28 and has two electromagnets 14 and 15 for controlling a ferromagnetic slab 13. The ferromagnetic slab 13 forms a capacitive sensor in cooperation with two electrodes 33 connected to the electronic control circuit 28. The two electrodes and the electronic control circuit are borne by two printed circuit boards 29 and 30 which are fixed to an electromagnet. |
