What is the working principle of this flow sensor?

Using the Hall effect, the impeller with the two-pole magnet is placed perpendicular to the magnetic field, and the GS value generated by the rotation of the impeller is converted into a pulse signal output.

What are the specifications for the output signal?

The output signal is Pulse NPN or PNP, with red wire for positive, black for negative, and white for pulse signal output.

What is the minimum order quantity?

The minimum order quantity is 1 PCS.
