Type 1 50mm Rotary Sensor Assembly

This rotary sensor is 50mm diameter and measures absolute the angle of a target at up to 12mm gap.  Used in conjunction with a CTU chip, the system reports full absolute angular position over 360°.

End Shaft Operation
50mm rotary sensor alignment with target (end shaft)


  • Simple non-contact target
  • Large gaps & misalignment (end shaft operation)
  • Full absolute sensing over 360°
  • Standard 4-layer PCB process
  • 48mm diameter copper coil pattern
  • Highly repeatable

Performance (End Shaft)

  • ±0.6° (±0.17%) Absolute Error at gap 5…12mm
  • ±1.4° Absolute Error at Radial Misalignment 2mm, gap 6…10mm
