Note 1: The standoff distance between the sensor board and the target magnet is highly variable. A magnet of sufficient strength,
however, must be used to maintain a magnetic field strength of 80 gauss (min.) at the sensor array and an apparent
magnet length of 23 mm.
Note 2: Sensor boards are factory calibrated in the axial mode using a 27mm cylindrical magnet. Operation in the radial mode
must be configured by the user.
Note 3: cf. "Magnet Considerations" (pg. 8)
