The pulser is a magnetic gear. |
|
 |
|
- Place the sensor face-to-face with the magnetic gear (pulser) so that the sensor's detecting direction is parallel to the gear's direction of rotation.
- Mount the sensor the specified gap from the pulser. Rotate the gear and measure the output value of Vp-p.

|
- The pulser is a magnetic shaft that is gear-cut.
|
 |
|
- The sensor is mounted the specified distance from the shaft. It outputs a signal according to the rightward and leftward motion of the shaft.
