Abstract
A magnetorheological braking device for setting operating states by way of rotational movements has an axle unit and a rotary body rotatable about the axle unit. The rotatability of the rotary body can be decelerated and/or blocked by a magnetorheological braking apparatus. A sensor apparatus has a magnetic ring unit and a magnetic field sensor for sensing a magnetic field of the magnetic ring unit. A shielding apparatus at least partially shields the sensor apparatus from a magnetic field of a coil unit of the braking apparatus. The shielding apparatus includes a shielding body surrounding the magnetic ring unit and a separating unit between the shielding body and the magnetic ring unit, and having a magnetic conductivity multiple times lower than the shielding body. A holding apparatus connects the shielding apparatus to the rotary body in an at least partially rotationally fixed manner.
