Stepper motor and proximity sensors

Hi All

I have a stepper motor driven distribution valve I am trying to use. From what I can see there is several hall effect sensors. I am trying to figure out what the output is on the IDC connector or some direction on reading from the sensors. I am thinking of using a bigeasy driver for control and using the sensors for positioning. Any help is appreciated.


several hall effect sensors

I don't think so.

It looks like a beams of light are interruped when the shaft is rotated. Slotted opto switches. O/Ps would be digital high/low.
