Abstract
The device comprises: an actuator unit arranged to apply a tension force on a pair of operating cables provided with a sheath; and a force sensing unit for providing a signal indicative of the force applied the sheath by either of the two operating cables (12a). The force sensing unit comprises: a pack of Belleville springs coupled to an end portion of the sheath and arranged to deform as a result of the tension force applied by the actuator unit on the operating cable; and a Hall position sensor for detecting the displacement of the end portion of the sheath as a result of the deformation of the pack of springs.
