ALLECIN 49E Hall-Effect-sensor, 3-polige magneetdetector OH49E Lineair Hall Effect Sensor SS49E TO-92S voor elektrische voertuigen, motorreparatie (verpakking van 20 stuks)

The one I tried worked. I had to look up the pin-out -- with leads down and the angled sides facing you (the flat side facing away from you), the left is +5VDC, middle is GND and the right is the output. Nominal output is 2.5VDC with no magnetic field. The direction of the output changed when the magnet was reversed. With just one 1/4" diameter disk magnet, the voltage range was 4.24V and the low was 0.80V with the magnet at the sensor; with two magnets the low went to 0.75V, the high was the same.With the two magnets, the output changed by 0.001V about 6 inches but remained that way until about 1/2 inch where the voltage was about 2.63 volts -- 0.13V change. A 3-inch stack of magnets was 2.68V. A 1 inch disk magnet gave 3.25V at 1/2 inch and 2.75V at 1 inch distance. At 2 inches the 1-inch magnet gave a change of 0.04V from the 2.5V nominal.

Hab damit meinen Joystick von Potentiometer auf Hall Sensor upgegraded... (Z-Achse)

J'ai fait un test de continuité entre les 3 broches de ces capteurs à effet Hall avec un multimètre il n'y a aucune continuité c'est bizarre.

A circuit you can build is a wind direction vane using multiple Hall Effect Sensors.

Using these on my first flight stick build and as far as I can tell they work pretty flawlessly!
