Abstract (en)

A sensing device comprises an axially magnetised hollow magnet 24 and means 5 for sensing magnetic field changes movable into and out of the magnet 24, the sensing means 5 being aligned to generate a first potential difference when the sensing means 5 is inside the magnet 24 and a second, different, potential difference when the sensing means 5 is outside of the magnet 24, detection of the first and second potential differences being indicative of the position of the sensing means 5 with respect to the magnet 24. An end of travel sensor 10 employing the sensing device is also disclosed. <IMAGE>
