Magnetic transmission park position sensor

A transmission range selection sensor comprising:

• a housing defining a bore extending along a central axis;
• a piston slideably disposed within the bore and moveable along the central axis between an in-park-position and an out-of-park position;
• an actuation lever engaged with the piston, whereby axial movement of the piston along the central axis moves the actuation lever for controlling a transmission gear range;
• a magnet carrier attached to and moveable with the piston;
• a magnet attached to and moveable with the magnet carrier, with the magnet generating a magnetic field;
• a first magnetic sensor attached to the housing and positioned at a first axial position along the central axis;
• a second magnetic sensor attached to the housing and positioned at a second axial position along the central axis, with the second axial position spaced from the first axial position along the central axis;
• at least one magnetic flux concentrator attached to one of the magnet carrier or the housing, and operable to enhance the flow of flux in a direction of either the first magnetic sensor or the second magnetic sensor as a function of a position of the magnet.
