Re: A poximity sensor that works with IFI gear

OK, here is that i wanna do:

The winch on our but is made out of renboard (a plastic composite). We have no way of sensing its position. there is no way to do a pot, we already tried.

We have 2 options, both involve drilling 4 really small holes at 90 degree intervalls in the center of the winch (the cable never gets that far, the drum is threaded). Ofter that we either glue 4 magnets or screw in 4 screws. If we have screws we would have proximity sensors that cound every screw going by (4 counts=1 turn). If we used magnets then we would use reed switches to count.

I like the proc switches better then reed switches and we may be able to use the hall effect gear tooth sensors if we can find them.
