(57) An electronic security device is suitable for showcases, drawers, cabinets and the like, wherein a front plate can be moved away from a storage compartment. The device comprises a locking pin that is oriented transversely to said front plate in the direction of the storage compartment. Furthermore, a magnetic valve is provided with a catch that can be retracted in lateral direction from the locking pin by an electromagnet against the action of a spring. A selection means detects the retracted/projecting position of the catch. Guide means guide the locking pin in its reciprocating movement.
In particular, the locking pin made of a non-magnetic material houses a permanent magnet, and a detector element is fastened to the guide means for distinguishing the field of the permanent magnet without interference from elements of the field of the electromagnet that are of a low spatial order.
