  • the two-part coil cup surrounding the coil winding not only concentrates the field lines in the center of the coil, but rather field lines that are in the vicinity of the coil are also used to drive the plunger of the coil. Dividing the coil cup into two enables the field lines to be captured by the coil cup in every position of the plunger and used to drive the plunger. As a result, the force transmitted from the coil to the plunger is increased, or the installation space or the installation volume required by the coil can be reduced while the force remains the same.
  • the two parts of the coil can are arranged concentrically.
  • the two parts of the bobbin can have the same diameter. It is preferably provided that the plunger is arranged in the center of the bobbin case.
  • the locking member acted upon by the plunger can be designed as a locking member movably mounted in the door opener housing, in particular as an anchor or as a change of the door opener.

  • the two coil parts can be connected electrically in series in order to operate the door opener at a higher voltage, or can be connected electrically in parallel in order to operate the door opener at a lower voltage, in particular at half the voltage.
  • the door opener can be designed for 24 V operation. To operate the door opener at 12 V, the two coil parts are connected in parallel. Due to the parallel connection of the two coil parts, the same force can be obtained as with 24V operation despite the reduced voltage.
  • the bobbin case In the sense of a high degree of efficiency, provision can also be made for the bobbin case to be designed to be closed at the bottom and / or at the front in order to reduce the magnetic stray fields.
  • the door opener has a digital bus interface with a switching device that interacts with the two coil parts to switch the operating voltage of the door opener between a higher operating voltage and a lower operating voltage by remote control.
  • the door opener can have a control device which switches both coil parts for a preferably adjustable period of time from serial connection to parallel connection and then back on again switches back in series to increase the holding force or release force of the door opener.
  • the short, preferably adjustable time span can be set in the range between 1 ms or up to half a second (500 ms). Due to the brief parallel operation of the two coil parts, the coil parts are each subjected to a higher operating voltage than would be permissible for continuous operation. However, this increases the magnetic flux density produced by the coil, so that a significantly higher force can be generated. In order to prevent overloading of the coil, the adjustable period of time is limited to a relatively short time.
