Abstract
An arrangement and a method for an electromagnetic padlock (10) are disclosed. A handheld unit (30), which is movably connected via a connector member to a lock fitting (50) to be locked by a padlock (10), is removably attached to a padlock (10) during unlocking and locking. When the padlock (10) is locked, a magnetic sensor (44) of the electronic key (40) detects a change in detected magnetic flux from the attached magnet (31), 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.

A padlock arrangement for locking a lock fitting, comprising:
- an electromechanical padlock;
- an electronic key arranged to be inserted into the padlock to an inserted position in which the electronic key is rotatable between a lock position in which the padlock is locked, and an unlock position in which the padlock is unlocked, said electronic key being provided with a position detecting device having at least one magnetic sensor;
- and
- a handheld unit having at least one magnet, said handheld unit being movably connected to the lock fitting via a connector member and being detachably attached to the padlock in a position of use,
- wherein the position detecting device of the electronic key is arranged to detect the lock position of the electronic key, by the magnetic sensor detecting a first magnetic flux from the magnet of the handheld unit being attached to the padlock, as a verification that the padlock is locked and the handheld unit is attached to the padlock.
A method for providing status of an electromechanical padlock, said method comprising:
- removably attaching a handheld unit to a padlock, said handheld unit having at least one magnet and being movably connected via a connector member to a lock fitting to be locked by the padlock;
- while the handheld unit is being in its position attached to the padlock, locking the padlock by turning an electronic key inserted into the padlock, said electronic key being provided with at least one magnetic sensor which, by said turning the electronic key for locking the padlock, is rotated to a rotational position where a first magnetic flux from the at least one magnet of the attached handheld unit is detected by the magnetic sensor, representing a verification that the padlock has been locked while the handheld unit is attached to the padlock.
