A speed sensor for a rotating component in an aircraft engine includes a phonic wheel, mounted for rotation with the rotating component, including a disk body having a first axial face, a second axial face axially spaced apart from the first axial face, a radial surface extending axially between the first and second axial faces and extending circumferentially, and teeth extending from the radial surface, the teeth being circumferentially spaced apart by circumferential gaps defined between the teeth. A shroud extends in a circumferential direction about the phonic wheel. The shroud extends radially to obstruct the circumferential gaps defined between the teeth of the phonic wheel the first and/or second axial faces. A sensor is mounted proximate to the phonic wheel to generate a sensor signal when the teeth of the phonic wheel pass the sensor as the phonic wheel rotates.
