Zusammenfassung:The invention relates to an electric or electro-pneumatic pedal device of a vehicle for inputting request signals of a driver of the vehicle, which pedal device contains at least the following: a housing (4), which has a cover (38), a bottom, and a jacket (54), which connects the cover (38) to the bottom; a foot pedal, which can be actuated by means of the foot of the driver; and an inductive sensor device arranged in the housing (4), comprising a magnetic coil assembly (42) containing at least one magnetic coil (12a, 12b) through which current flows, and containing a stationary coil former (44), which has a coil former opening (48) and onto which the at least one magnetic coil (12a, 12b) is wound, which generates a magnetic field at least in the interior of the coil former opening (48), and containing at least one electrical contact element (50) protruding away from the magnetic coil assembly (42) radially outward, which at least one electrical contact element is connected to the at least one magnetic coil (12a, 12b), and comprising at least one plunging body (6), which is movably supported in the housing (4) and plunges into the coil former opening (48), wherein the inductance (L) of the at least one magnetic coil (12a, 12b) varies in accordance with the plunging depth of the plunging body (6) into the coil former opening (48), and comprising evaluating electronics (14), which are in electrical contact with the electrical contact element (50), wherein the plunging body (6) is operatively connected to the foot pedal in such a way that the plunging depth of the plunging body (6) into the coil former opening (48) depends on a degree of actuation of the foot pedal, and the evaluating electronics (14) are designed in such a way that the evaluating electronics generate a pedal actuation signal in accordance with the plunging depth of the plunging body (6) into the coil former opening (48). According to the invention, the jacket (54) of the housing (4) has a peripheral opening (56), through which the magnetic coil assembly (42) can be inserted into the housing (4) in the manner of a drawer in such a way that the at least one electrical contact element (50) is arranged in the region of the peripheral opening (56), and at least one circuit board (34) populated with electronic components of the evaluating electronics (14) is fastened to the housing (4) in the region of the peripheral opening (56) in such a way that, during the fastening of the circuit board (34) t
