1. A sensor for sensing a moveable object, comprising:
- a housing defining first and second cavities;
a wall separating the first and second cavities;
at least one magnet positioned within the first cavity, the magnet generating a magnetic field, the magnet being adapted for movement in response to movement of the moveable object; and
at least one magnetic sensor positioned within the second cavity, the magnetic sensor generating an electrical signal that is indicative of a position of the moveable object.

Abstract
A sensor used to sense the position of an attached movable object. The sensor can be mounted to a pneumatic actuator. The sensor includes a housing that has a pair of cavities or pockets separated by a wall. A magnet carrier is positioned within one of the cavities and a magnet is coupled to the magnet carrier. The magnet carrier is coupled to the moveable object. A magnetic sensor is positioned in the other of the cavities. The magnetic sensor generates an electrical signal that is indicative of a position of the movable object.
