A disconnect tool can be part of a production string in a wellbore. The disconnect tool can include a disconnect sub and a disconnect receptacle. The disconnect sub can be inserted into the disconnect receptacle such that the disconnect sub is concentric with the disconnect receptacle. The disconnect sub and the disconnect receptacle can include bands having multiple electrically conductive sections separated by an electrically insulating material. Insertion of the disconnect sub into the disconnect receptacle cause the electrically conductive sections of the disconnect sub to contact the electrically conductive sections of the disconnect receptacle, thereby completing multiple electrical connections between a control system uphole of the disconnect tool and one or more devices downhole from the disconnect tool along the lower portion of the production string. The disconnect tool allows the upper portion of the production string to be removed leaving devices in the lower production string undisturbed.
