Abstract
A disclosed apparatus includes a sensor housing. First and second magnets may be disposed in the sensor housing. A magnetic field sensor may be disposed between the first and second magnets. A sensor element may be positioned in a vicinity of the sensor housing, the sensor element to cause a magnetic field between the first and second magnets to substantially bypass the magnetic field sensor. The sensor housing may be coupled to a movable rail. The sensor element may be coupled to a fixed rail. The movable rail may be engaged with the fixed rail and movable relative to the fixed rail.
Claims19
An apparatus, comprising:
- a sensor housing;
- first and second magnets disposed in the sensor housing;
- a magnetic field sensor disposed between the first and second magnets;
- and
- a sensor element positioned in a vicinity of the sensor housing, the sensor element to cause a magnetic field between the first and second magnets to substantially bypass the magnetic field sensor.
An apparatus, comprising:
- a fixed rail;
- a movable rail engaged to the fixed rail, the movable rail movable relative to the fixed rail;
- a sensor housing including a plurality of magnets and a magnetic field sensor, the sensor housing coupled to the fixed rail or the movable rail;
- and
- a switching plate coupled to the fixed rail or movable rail that does not include the sensor housing, the switching plate to cause to cause a magnetic field between the first and second magnets to substantially bypass the magnetic field sensor.
