Basic Dimensions



The TULA exploits the vibration mode of piezoelectric ceramic, the inertial principle, and the contact friction between the shaft and the mobile to produce stepped linear motion. Some of the key features include:

  • Very small size with a lightweight and simple structure
  • Variable stroke
  • Quick response
  • Intrinsic holding force
  • Excellent controllability
  • Fine positioning/High resolution
  • Quiet operation
  • No EMI

Applications of TULA35

These two examples show the TULA35 used in an X-Axis Stage and in an Auto-Focus mechanism for a camera. Additional applications can be seen in the Piezoelectric Stage Catalog. Contact us for additional information and pricing on any of the stages and mechanisms shown.
