Abstract

A sensor which is intended to detect the rotational position of a rotatable device, e.g. a shaft or a rotatable hatch, which is rotatable, preferably by a motor, incorporates a position detector and a potentiometer. To improve the potentiometer's accuracy within part of the relevant rotation range of the device, a cam mechanism is arranged between the potentiometer and the rotatable device.
