How to choose potentiometer

I don't know for JRK but Arduino built in ADC (analog to digital converter on Analogic pins) is optimized for 10k ohm

Hi
When i understand that right ,hall pots are plug and play to ardinio?
I have crashd my normsl pot,and wil by hall pots.
Normaly can i replace the normal with the hall pot,or is tomthing to do?
Sry for my bad english :-(

Thanks for the information, but one more question I have
Need hall sensors a magnet on the shaft, or can i built them nearly to the shaft and it works?

the position/hall sensors are stand alone. same as a potentiometer.
here are a couple more examples/links.

Hello,
Interesting mechanical angle and electrical angle 360 °.
Mine are mechanically 360 ° but 340 ° electrical angle, so with a dead zone of 20 °
Your potentiometers with the mechanical angle and electrical angle 360 ° were they an operating shaft 6mm and 6.35mm?


Bonjour,
Intéressant l'angle mécanique et l'angle électriques à 360°.
Les miens sont des 360° mécaniquement mais des 340° pour l'angle électrique , donc avec une zone morte de 20°
Vos potentiomètres avec l'angle mécanique et l'angle électriques à 360° ont-ils un axe de manœuvre de 6mm ou de 6,35mm ?

Hello,
I just found the answer by reading the datasheet for a pin 6mm I need the model 6124

Bonjour,
Je viens de trouver la réponse en lisant le datasheet, pour un axe de 6mm il me faut le modèle 6124

FYI: I bought that Hall effect potentiometer 3 years ago and today I had one disintegrate on my hands while cleaning! i guess the housing is plastic and with time they come apart easy

Im still on my Original set in which were LOCKED up twice (due to too Rigid of Pot mount) and required BIG BIG pliers to free up.

They are FAR from Fragile if you ask me.

A question, about, these Hall potentiometers:
how can I put the value in the middle when I will mount the potentiometer on the motor axe?

Thanks in advance

Apply 5v from Arduino or other source. Use volt meter and twist pot until output reads 2.5v.

Thank you very much!!!

Where do I buy this pot? Any Chinese website?

You can go to (Taobao), the price is about 10 dollars.

Hi, I recently bought these hall effect gyro sensors to replace my old Bourns 5 ohm potentiometers.

https://www.ebay.es/itm/Hall-angle-...rand=Unbranded&_trksid=p2047675.c100012.m1985

And now that I want to change them, a question arises: I know that I can change the polarity of the bourns, that is, I can invest as appropriate between vcc and gnd so that it goes hand in hand with its motor. But I don't know if I can do the same with these new sensors.
I hope I have explained myself well.

Sorry, I answer myself: can´t reverse vcc and gnd on hall sensor.
I just found the answer.

Hi, i buyed 360 deg hall sensors pot but i want connect it directly to the motor shaft without any gear, so this is my question . do i need make some adjustment in the smc3 ino file in the arduino to get the right feedback from the pots????? Or it can be adjusted with the clip limit??? Thanks in advance

Just to add, there are also Hall sensors that have separate magnets and sensors. While you need to be careful to get the magnet aligned with the sensor axis, that’s pretty easy to do with 3D printing and there is no bearing to gall and bind. Just make a mount for the magnet that fits to the rotating part and a mount for the sensor itself that is fixed in position. Besides the need for proper magnet alignment in the X-Y plane of the sensor, there is also a distance requirement between the magnet and sensor but these are all less demanding than alignment with the shafted Hall sensors. Plus, separate magnet Hall sensors need no lubrication because nothing touches or rubs. I used separate magnet Hall sensors and they have been totally trouble free with the only issue being my output arms hit early versions on my sensor mounts and broke them. That was preventable and entirely my fault. Operationally, no issues at all with the Hall sensors. Highly recommended - shafted or free.
