Rotary position sensors of type DWA-Q are mechanically connected rotary position encoders. They are suitable for measuring the rudder or pitch position, for example. Besides different mechanical designs, they are available with the following electrical output signals:

  1. Version with ohmic signal output (dual potentiometer 2 kΩ)
  2. Version with analogue voltage output (2 … 10 VDC)
