Rotary position sensors

Mechanically connected rotary position sensor, ohmic principle


Rotary position sensor DWA

  • 360° rotation angle without mechanical limitation
  • Reference positions easy to adjust mechanically
  • Maintenance-free operation
  • No reference run necessary
  • Potential-separated channels


Rotary position sensors of type DWA are mechanically connected rotary position encoders. They measure the rotary position in accordance with the ohmic principle. These rotary position sensors are suitable for measuring the rudder or pitch position, for example.
