Abstract
A door lock with integrated door position sensor includes rectangular magnets positioned behind the door strike to maximize magnetic field strength in available space limited by industry-standard dimensions for the door strike. A beveled or stepped mounting opening for the sensor is formed in a front plate of the door lock and behind a non-magnetic faceplate. The shape of the mounting opening allows the magnetic field to penetrate deeply through the faceplate and front plate to actuate the door position sensor. The sensor may be used in mortise locks or bored locks. In an alternative embodiment, the sensor is spring mounted to eliminate all mounting tolerances and ensure that the sensor is maximally forward and flush against the back of the non-magnetic faceplate.
