Abstract
The magnetic sensor in the invention includes a detecting section that detects a change of magnetic flux due to a movement of the magnetic movable, comparator circuits constituting a converting section that converts a change of magnetic flux detected by the detecting section into an electric amount, and a D-FF circuit device, in a sensor unit having a power-supplying power terminal VB, a ground terminal GND and an output terminal VOUT. A current control section is provided to change the amount of current flowing through at least one of the power terminal and the ground terminal, correspondingly to a moving direction of the magnetic movable. Thus, a moving direction of the magnetic movable can be determined depending upon the amount of current.
