More Information
Summary:A lock cylinder including a plug, a plurality of key followers, a sensor assembly structured to sense positions of the key followers, and a controller in communication with the sensor assembly. The plug includes a keyway and a plurality of plug tumbler shafts. Each of the key followers is movably seated in a corresponding one of the plug tumbler shafts and includes a sensor interface. The sensor assembly includes a plurality of sensors, each of which includes at least one sensing region. Each of the key followers is associated with one of the sensors via an associative link formed between the sensor interface and the corresponding sensing region. The sensors are structured to generate an output signal indicative of the transverse position of the associated key follower, and the controller is structured to select and perform actions based upon the output signals.
