A sensor which is intended to detect the rotational position of a device (e.g. a shaft (21) or a rotatable hatch (20)) which is rotatable preferably by a motor (24) incorporates a position detector and a potentiometer (25). With a view to improving the latter's accuracy within part of the relevant rotation range of the device, a cam mechanism (2,5,8,30) is arranged between the potentiometer (25) and the rotatable device (20,21). <IMAGE> |
