Detects both forward and reverse rotation with one sensor (compatible with gears m1/1.5/2, verified with involute gears)./p>
Helps reduce labor costs such as drilling and installation adjustments.
Detects rotation of magnetic gears from 0 Hz, allowing detailed monitoring of start and stop movements.


Contributes to cost reduction by eliminating drilling and adjustment work during installation.

Extending the sensor cable increases susceptibility to external noise.
The impact depends on conditions, so it is recommended to verify performance in the user's environment.
