Type 1 36mm Rotary Sensor Assembly

This rotary sensor is 36mm diameter and measures absolute the angle of a target at up to 8mm gap.  Used in conjunction with a CTU chip, the system reports full absolute angular position over 360°.

36mm rotary sensor alignment with target

  • Simple non-contact target
  • Large gaps & misalignment
  • Full absolute sensing over 360°
  • Standard 4-layer PCB process
  • 35mm diameter copper coil pattern
  • Highly repeatable


  • ±0.5° (±0.14%) Absolute Error at gap 1…8mm
  • ±1.5° Absolute Error at Radial Misalignment 2mm, gap 1…3mm
  • ±3° Absolute Error at Radial Misalignment 2mm, gap 1…7mm
