Hall sensor for driveshaft speed

[dart440]

Hi:

I am attempting to install a driveshaft speed sensor on my RWD race car. I have a Racepak split collar mounted onto the differential yoke. It is aluminum with two magnets embeddid into it.
What kind of sensor do I need to get?. I would prefer not to buy the Racepak sensor ($150). Is there a generic sensor I could use?

Thanks

You could certainly make one easily and cheaply if you have some fabrication skills. You get a suitable sensor IC and mount it in a tube or screw using epoxy like "JB Weld". We can provide details if you want to go that route. Lots of folks here have done that.

thanks.
I tried a mopar crank sensor, but it wont work. I need to find a sensor that will trigger from the magnets and not a tone wheel.

I remember msd selling a magnet based crank trigger for a gen 1 small block

Maybe they can sell just the sensor?

Well, they do but it's $150 and I'm cheap!

Do what Bill said if you want to be cheap. Likely around $1 for the bare hall effect sensor.
