Abstract
Passive entry sensor systems and associated sensors are disclosed. The system sensor is locatable in the handle of a door or like structure and can provide an electromagnetic radiation beam transmitted either along the length of the handle between opposite ends thereof or between the handle and the door such that the sensor can detect at least a partial interruption of the beam by a user actuating the handle. The system can include an independent optical locking switch for actuation by a user to lock the door which locking switch comprises a shutter for intercepting the beam so as to flag the sensor. The system can include a power-up switch for actuation by a user to power-up the system, back-up switches for detecting a pull on the handle, indicators for indicating system status to the user, and backlight and ground light lighting.
