VR speed/position sensor
VR (variable reluctance) sensors are of the inductive (passive)
type, requiring no power supply. They measure variations in the magnetic fl ux generated by a target on the shaft, delivering an electrical signal that the electronic control system processes to determine the speed and/or angular position of the rotating shaft. A VR sensor is made up of a wire-wound coil, a pole-piece and a magnet.
