Does a Tach. sensor actually count RPMS or just generate a voltage?
I'm working on making a counter for a pickup coil winder for my guitars (I build electric guitars for a living) and have been relentlessly searching for a sensor that will be able to keep up with the RPM's of the spindle.
I was wondering if I could buy a MB part to use for the input device to my counter? I've used Reed Switches and they only get up in the low thousands. Obviously our car's tack gets in the 5k range which is closer to what I'm looking for. Is there a switch on the MB engine actually ticking away, or just a little generator somewhere creating a proportional voltage?
