Abstract
An arrangement and a method for an electromagnetic padlock () are disclosed. A handheld unit (), which is movably connected via a connector member to a lock fitting () to be locked by a padlock (), is removably attached to a padlock () during unlocking and locking. When the padlock () is locked, a magnetic sensor () of the electronic key () detects a change in detected magnetic flux from the attached magnet (), representing a verification that the padlock has both been locked and locked at a correct location. Incorrect locking procedure, or locking at incorrect locations may generate warnings.
