Abstract: Disclosed is a magnetic encoder for determining a position of a first object relative to a second object. The encoder comprises a first magnetic member, a second magnetic member and a sensor member. The sensor member comprises 5 a first sensor for measuring a change in magnetic field of the first magnetic member for deducing an unsigned absolute position of the first object relative to the second object, and a second sensor for measuring a change in magnetic field of the second magnetic member for deducing a sign for the unsigned absolute position. The first magnetic member and first sensor are coupled to 10 respectively different ones of the first object and second object, and the second magnetic member and second sensor are coupled to respectively different ones of the first object and second object.
