R30D series


R30D – DC Operated, Light Weight RVDT


The R30D RVDT (Rotary Variable Differential Transformer) is a DC operated non-contacting rotary position transducer. Integrated signal conditioning enables the R30D to operate from a bipolar ±15 VDC supply, and provide a high level DC output that is proportional to the full angular sensing range of the device. Calibrated for operation over ±30 degrees, the R30D provides a +/-3.75VDC output, with a non-linearity of less than ±0.25% of full range. Extended range operation up to a maximum of ±60 degrees is possible with increased non-linearity.


  • Extended operation up to ±60o
  • High level, low noise DC output
  • Long term reliability
  • Excellent temperature performance
  • Rugged anodized aluminum housing
  • Shielded ABEC 3 precision bearings
