Pneu-Turn® Position Feedback

The Bimba Pneu-Turn® Position Feedback rotary actuator (PTF) provides continuous shaft position sensing.  Standard features include shaft ball bearings and the elimination of mid-rotational backlash.  Use the Bimba PTF in conjunction with Bimba's Pneumatic Control System (PCS) to achieve rotary shaft positioning accuracy within ± 0.5°.

  • Bore sizes:  1-1/2", 2"
  • Rotary potentiometer assembly mounted inside the actuator
  • Standard angles of rotation range from 45° to 325°
  • Pressure rating:  150 PSI (air or oil with "S" option)
  • Rotational tolerance:  0° to 10°
  • Single and double rack models have zero mid-rotational and end of rotation back-lash
