| Explanation of operation |
Switches on/off when the magnetic fields from the S pole and N pole of the magnet are applied alternately.
This is principally applied in detection of revolution speed. |
 Schematic operation drawing |

|
|
When the S pole of the magnet approaches the marked side of the Hall effect IC and the magnetic flux density exceeds Bop, Vout changes from H to L.
When the N pole of the magnet approaches the marked side of the Hall effect IC and the magnetic flux density exceeds Brp, Vout changes from L to H.
