Your thinking is correct in that the magnet is buried in the sensor. I don't know if the 0.1uF cap I have between power and ground at the sensor end is strictly required, but it makes me feel better.
It really is as simple as wiring into the digital sidecar and counting pulses. We used two of these last year and will be using three this year.
