The tracker assembly includes a tracker body defining a chamber configured to receive a printed circuit board (PCB) including a plurality of markers that are actively energizable through the PCB. A plurality of openings formed in the tracker body and at least one channel formed in the tracker body extending between the chamber and one of the defined by the tracker body. Each of the markers are visible through one of the plurality of openings of the tracker body. The tracker body is configured to be sterilizable, with the PCB being located within the chamber of the tracker body, and the at least one channel is configured to enable sterilization fluid to enter into and drain from the chamber of the tracker body during sterilization. The PCB may also include a sterilization resistant protective coating.
