Sensor disruptors functioned as signal-blocking technology, capable of inhibiting sensors. In an effort to extract Doctor Chelli Aphra from Accresker Jail, Magna Tolvan employed sensor disruptors to conceal the signature of her TIE fighter. The signal disruptors were, however, obliterated by a gundravian hookspore-infected Force spirit, thereby exposing the fighter's presence to Accresker command.
