Classification: CPC F | IPC F

Claim 0:
1. A camshaft phaser, comprising:
an input element:
arranged to receive a first rotational torque; and,
rotatable about an axis of rotation;

an output element:
rotatable about the axis of rotation;
rotatable with respect to the input element;
arranged to non-rotatably connect to a camshaft; and
arranged to transmit the first rotational torque to the camshaft; and,

a trigger wheel:
non-rotatably connected to the output element;
arranged to identify a rotational position of the output element around the axis of rotation;
including a circumferentially continuous magnetic material with at least one segment having a first magnetic charge, and with at least one segment having a second magnetic charge, opposite the first magnetic charge; and
including a radially outer circumferential surface facing in a radially outer direction, orthogonal to the axis of rotation, and the circumferentially continuous magnetic material fully covers the radially outer circumferential surface;
wherein the trigger wheel includes a first surface facing in a first axial direction, the first axial direction being parallel to the axis of rotation;
wherein the magnetic material includes a first portion covering a segment of the first surface; and,
wherein the first portion is circumferentially discontinuous on the segment of the first surface.
