Stack Sensor

[2cv7]

Hi. Has anyone fitted a Revotec ss34-1 speed sensor in place of a stack st 670, for a Stack 8130.
Cheers

Almost any PNP proximity switch that's fairly heat resistant will do.

Ideally you choose one with a detection range around 1mm.

Thanks. I thought it should be, but was interested to find out if anyone had used one and for how long etc.

Can't tell that.

I've used an industrial sensor for more than ten years, where the main use of the car has been track (ab)use. The first sensor survived road use, but first time the brakes got really hot it expired.

Can't find anything in the archives.

And I couldn't find the spec on the Revotec web site, but Merlin have this:

There might be a conflict of interest but 213 Performance, the new UK service centre for Stack, have been very helpful to the Club...

And actually I have become a little in doubt if it has to be an NPN sensor and I have wired in a transistor to ensure the right "polarity" of the input for the dash. I know for certain that the sensor on my car is PNP as that's what I use everywhere.

- sorry, I'm getting old and senile. I would be able to check though. As the sensor has a connector and so does the Stack dash, so with a multimeter I can simply measure if it's 0-ish ohms (wire) or acts like a transistor does...

Thanks for all the replies. I will check on some specs and see what happens...
