Technical Note of Rotary Sensors

回転センサの動作・検出原理を動画を用いて説明しています。

実際のセンサからの出力波形もご確認頂けます。

 



 Magnetic field concentrates on an element, and resistance changes.

 The wave pattern of the para-sine wave is generated by this resistance change.

 In case of dual output, the element is located every λ/4.

 Therefore the output wave pattern is provided with a phase difference of 90 degrees.


 
 
 

Pulse Z element detects a convex or a dent to be one.

 And it output a single-engine signal.
