We purchased some gear tooth sensors in hopes of using one of the gears in the K&T for a spindle encoder. Well - we ended up putting a shaft encoder in the gearbox.

If you rotate the spindle one direction it will pass the index and stay high until it passes the hole then you get a little index pulse low. If you run it the other direction it goes low after passing the index - and you get a positive index pulse at every passing of the hole. I think it should stay low (or high) no matter what direction the spindle is turning (and get a pulse every pass of the index hole). clear as mud? thanks sam ------------------------------------------------------------------------------ Transform Data into Opportunity.
