What is this sensor and what are its parameters (MCB 419311 potentiometer)

In search of something that I could add to the gas in my electric car, which I have been trying to make for some time, I hit the gas pedal of a forklift, where it mechanically fits perfectly into the structure. The sensor is probably broken, but I don't know that and I wanted to check it. Unfortunately, I was probably at the end of the internet and I haven't found one.
Maybe some of you had to do with what is shown in the attached picture. I suspect the hall effect sensor, but I won't give a head. I do not know the leads either, so I would not want to damage anything by rushing.

This is what it looks like

MCB-ELEKTRISCH 419216 potentiometer

Well, this is what I saw, but mine has 4 cables, and the one you write about - 3 and it looks a bit different

Do you know exactly what equipment it is from? maybe the part number will be more accurate. I do not know if this is the manufacturer's website, but https://mcbindustrie.com/ does not work for me, or the company is no longer there, or it is not this website.
Have you checked the resistance between the wires?

Unfortunately, I don't know. I will still ask the people from whom I got it, if they know what this model of the stroller is.
I cannot access this website either.

If the design suits you, then look at the Renault Premium pedal potentiometer. If something goes wrong, you will get another one right away without any hassle

There is "POTENTIOMETER 419336 LINDE 1163801105" on alledrogo, it looks similar

Or write to the frogs, send a photo, maybe they will send something "infomalpamcb-industrie.com"

@onepiotr, no, I will not be charged. Most likely, I will strip the reptile and transform it my own way. Specifically, I want to use this housing, because it is cool, and to it I put an analog hall effect sensor and a small magnet - I have already done tests and they turned out very promising (good stability of parameters when the magnet rotates), and above all, the path will not wipe out, because it will not be like that :)

@ gradek83, I took the measurements and if between the black and the extreme yellow and green it behaves like an ordinary logarithmic potentiometer (the resistance in the direction from green to yellow drops faster and faster from the extreme position in the range of 4.25k to 1.73k), then with a red cable I have such miracles that it's even hard for me to describe them here (there is no logic at all) - maybe that was the reason for replacing the accelerator pedal module.

I wonder how they did it there. Only this housing looks to me as flooded or welded or ultrasonically glued or in some other way. Squeeze it in a vise or cut it open with a hair saw Let me know if you have succeeded :D

And besides, from what I can see, they call themselves 200-500 PLN for such a potentiometer.

Price ... that's it For a hall effect sensor and a magnet, it will cost me 2-3 zlotys + some free time.
The most important thing is to disassemble this casing somehow, because it is probably ultrasonically glued

Well, it's not this one, buddy @ gradek83, look closely at the photo - it's MCB 419311.
Another thing, MCB was bought by Vishay, so the email you provided is out of date.

The mere fact that this potentiometer is only a comparison to another model with a different marking, because it is clearly visible in the attached photo that SylwekK gave. MCB probably makes such elements for a specific recipient under special orders. But it doesn't matter anymore, what matters now?

It might not even be a potentiometer.

Undress it, find out what's in there, we'll find out.

Curiosity won, and at the same time there will be information for posterity Taking into account the strange and illogical indications (which does not surprise me anymore and you probably will also stop after seeing the photos), I decided to undress the reptile. He gave up relatively easily. It turned out that it was only slightly glued at the edges, which could easily be delaminated with a knife and remove the lid.
However, there is a potentiometer inside. On the attached pictures you can see exactly how it is built and how the resistance path is used - it had no right to work properly anymore. The upper slider is resistance, the lower two are the connection terminated with sputtered resistors (the tabs on the right side of the tracks).


Finally, the housing is already in the workshop and is trying to sensibly stuff a magnet with a linear hall effect sensor into it.

I wonder if it would be able to somehow fill these worn-out deficiencies and regenerate, but what such something is made of, some graphite or nickel, silver, carbon.

There are pens like this:
Conductive Nickel Pen
Bare conductive Electric Paint

And the insides have been modified
After assembly and testing, it looks like this:


In terms of changes around 3 V, I can easily handle some PWM
