A track-guided power door operator used to simultaneously open a set of opposing hinged doors is disclosed. The door operator comprises a pair of articulated arm linkages, each pair of which is pivotally mounted at One end to a vertically oriented pivot pin at one end of a guide member and pivotally connected at the other end to a vertically oriented pivot pin of a yoke member of a translating carriage, which is engaged by a horizontal lead screw. Translation of the carriage member due to rotation of the lead screw causes lateral separation between the knuckles of the articulated arm pairs to cause doors contacted by the knuckles to rotate about their respective hinges. The door operator may include a control unit to control operation of the doors. The operator may further include magnetic latches to lock the doors closed.
