Swash plate angle sensor for NFPE and AC2 controls
The angle sensor detects the swash plate angle position and direction of rotation from the zero position.
The swash angle sensor works on the AMR sensing technology. Under the saturated magnetic field, the
resistance of the element varies with the magnetic field direction. The output signal give a linear output
voltage for the various magnet positions in the sensing range. The swashplate angle sensor is available
for all NFPE and AC2 controls.
