Abstract
The latching components of the padlock are driven by a motor between positions for latching and releasing the padlock shackle. Power for the motor is provided by a source carried in an electronic key. An encoder element with associated optical elements provides position information to the control circuit carried inside of the padlock. The control circuit correlates the position information with the signal directing power to the motor so that the motor is precisely controlled for moving the latching elements between release and latch.
