Sensor device for determining relative position, electronic device including same and method for determining relative position

A method for determining a relative position between parts, the method comprising:

• detecting a magnetic flux value through a sensor physically coupled to only one of a first part or a second part such that the sensor faces a magnetic member physically coupled to the first part, when the sensor is physically coupled to the second part, or the second part, when the sensor is physically coupled to the first part;
• and
• determining a relative position of the second part to the first part using the detected magnetic flux value,
• wherein the magnetic member includes a body extending in a movement direction of the second part and two magnets respectively physically coupled to opposite ends of the body such that a north pole of one of the magnets is adjacent to the body and a south pole of the other of the magnets is adjacent to the body.

A sensor device comprising:

• a magnetic member physically coupled to only one of a first part or a second part configured to be movable with respect to the first part;
• and
• a sensor physically coupled to the first part, when the magnetic member is coupled to the second part, or the second part, when the magnetic member is physically coupled to the first part, such that the sensor is facing the magnetic member,
• wherein the magnetic member includes a body extending in a movement direction of the second part and two magnets respectively physically coupled to opposite ends of the body such that a north pole of one of the magnets is adjacent to the body and a south pole of the other of the magnets is adjacent to the body.
