Door position sensor for an electromagnetic door lock

A strike plate assembly of an electromagnetic door lock configured to be mounted to a door, wherein said door is pivotally coupled to a door frame, wherein electromagnetic lock includes an electromagnet, and wherein at least one sensor is connected to the door frame, said strike plate assembly comprising:

• a) a strike plate configured to be movably mounted to said door;
• b) a strike tray configured to be fixedly mounted to said door and disposed between said strike plate and said door, wherein said strike tray includes a first side edge and a second side edge, wherein said first side edge and said second side edge define at least a portion of a cavity, wherein said strike plate is slidably received within said cavity, and wherein said first side edge and said second side edge each have a sufficient thickness to abut said strike plate such that said strike plate remains in alignment with said door through movement of said strike plate relative to said door;
• and
• c) at least one permanent magnet fixedly positioned relative to said strike tray so that said at least one permanent magnet does not move relative to said strike tray, wherein said at least one permanent magnet is configured to align with said at least one sensor when said door is closed, wherein movement of said door away from said door frame is detected by said at least one sensor to generate a signal, and wherein said signal is received by said electromagnet to selectively provide power to said electromagnet as a result of said movement of said door away from said door frame.

A strike plate assembly of an electromagnetic door lock configured to be mounted to a door, wherein said door is selectively movable within a door frame, said strike plate assembly comprising:

• a) a strike plate configured to be movably mounted to said door;
• b) a strike tray configured to be fixedly mounted to said door and disposed between said strike plate and said door, wherein said strike tray includes a cavity for receiving said strike plate, and wherein said strike tray includes a first side edge and a second side edge;
• c) a first permanent magnet fixedly positioned at said first side edge of said strike tray so that said first permanent magnet does not move relative to said strike tray, wherein said first permanent magnet is configured to align with a first sensor disposed on said door frame when said door is in a closed position relative to said door frame, wherein movement of said door away from said closed position toward an open position is detected by said first sensor to generate a first signal, wherein said first sensor is a Hall Effect sensor, and wherein said first signal is received by said electromagnet to selectively provide power to said electromagnet as a result of said movement of said door away from said door frame;
• and
• d) a second permanent magnet fixedly positioned at said second side edge of said strike tray so that said second permanent magnet does not move relative to said strike tray, wherein said second permanent magnet is configured to align with a second sensor disposed on said door frame when said door is in said closed position relative to said door frame, wherein movement of said door away from said closed position toward said open position is detected by said second sensor to generate a second signal, wherein said first second sensor is a reed switch, and wherein said second signal is received by said electromagnet to selectively provide power to said electromagnet as a result of said movement of said door away from said door frame.
