Solenoidsysteme and method for determining the stroke length

In some embodiments, a device comprises a solenoid and a solenoid control. The solenoid is adapted to move an armature by a distance between a first position and a second position when a voltage is applied to the solenoid. The solenoid control is constituted by a memory and / or a processor, and includes a feedback module and an output module. The feedback module is adapted to receive a relating to a solenoid current feedback signal after the voltage has been removed from the solenoid. The feedback module is further adapted to determine whether the value of the distance is less than a maximum distance between the first position and the second position (ie, a "hub") is. The output module is adapted to generate an output signal when the feedback module determines that the value of the distance is less than the maximum distance.
