Swash Plate Angle Sensor for EDC Controls

36 | © Danfoss | May 2018
The angle sensor detects the swash plate position with an accuracy dependent upon the calibration
effort done for the application and direction of rotation from the neutral position. At minimum the sensor
can be used for forward, neutral and reverse (FNR) detection.
The sensor works on the hall-effect technology. The implemented technology is based on a
measurement of the magnetic field direction in parallel to the chip surface. This field direction is
converted to a voltage signal at the output.
Enhanced calibration of the non-linear behavior leads to more exact calculation of the pump swash plate
angle.
The 4-pin DEUTSCH connector is part of the sensor housing.
The swash plate angle sensor is available for all EDC controls for 12 V and 24 V.

Strong magnetic fields in the proximity of the sensor can influence the sensor signal and must be
avoided.
