Piezoelectric walking drive
Millimeter travel with nanometer-scale adjustment
A piezoelectric actuator converts electrically induced changes in a piezoelectric material’s shape into motion. GO piezo actuators use repeated walking-drive cycles to produce millimeter travel with nanometer-scale adjustment.
An integrated optical encoder and GO Controller complete the closed-loop positioning system. Piezo walking drives deliver high force in a compact format, supporting demanding horizontal and vertical motion.

Why choose a PRECIBEO GO actuator?
Fine adjustment with closed-loop feedback
Position feedback supports fine adjustment across the full stroke, with typical bidirectional repeatability of ±200 nm. Compare repeatability and minimum incremental motion alongside sensor resolution.
High force in a miniature format
A 67 × 28 × 14 mm body delivers at least 10 N push/pull force, bringing precision linear actuation to instruments where mounting space is limited.
Smooth motion and fast settling
Combine smooth continuous motion with fast move-and-settle performance for repeated positioning and optical adjustment.
Self-locking at rest
The drive holds position without power, with at least 10 N holding force. Position the mechanism, then retain its setting without continuously powering the drive.
Horizontal and vertical motion
High force throughout the operating stroke
Both versions provide 10 N operating push/pull force. Their specified speed at maximum operating force is at least 1 mm/s, with a maximum no-load speed of 8 mm/s.
Size the complete mechanism
For vertical integration, include the moving load, friction and any spring or preload forces in the force requirement. Check the complete installation envelope: body, piston travel, mounting and cable clearance.
Fit the actuator using its 9.5 mm clamping shank or M9 mounting thread. The stainless-steel piston transfers motion to a compatible mount or custom mechanism.

Actuator or linear stage?
A GO actuator is a compact drive for your mechanism. It is well suited to motorizing an adjustment screw, optical mount or custom positioning assembly.
A GO linear stage adds a guided moving platform for mounting the payload. Choose the format around your mechanical design, guidance needs and mounting arrangement.
Build your system
Optical alignment and compact OEM integration
Use the actuator as a compact drive in your own mechanism, or combine two or three actuators with compatible mirror mounts for precise optical alignment.
Motorized mirror mounts and laser beam steering
Use two or three GO actuators with compatible mirror mounts for adjustment around the X and Y axes. Changing mirror angle changes the reflected beam direction for laser beam steering and alignment.
Build and control your actuator system
A GO Controller is required. Two daisy-chained controllers support six axes through one computer connection.
Connect over USB and choose GO Motion, GO Command, Precibeo ASCII Rapid commands, LabVIEW drivers or GO DLLs. The optional GO Joystick provides manual positioning alongside computer control.
Combine actuation and guided positioning
Combine actuators and compatible GO stages within the same control system to bring optical adjustment and sample positioning together.
Plan the number of axes, controller channels, mechanical interfaces and software integration as one system.
High vacuum
10⁻⁴ Pa
Vacuum-compatible linear actuation
GO-ACT1HV brings the same motion capability to environments down to 10⁻⁴ Pa. Its 0.5 m vacuum-side cable uses PTFE-coated wires within a braided metal sleeve and terminates in a female D9SUB connector.
The supplied 2 m air-side cable connects your compatible D9SUB chamber feedthrough to the GO Controller outside the chamber.
Motion
Match the 9 mm stroke, loaded speed and 10 N operating force to your mechanism.
Positioning
Compare minimum incremental motion and repeatability alongside sensor resolution.
Integration
Check the mounting interface, contact arrangement, available space and load direction.
Environment
Select standard or HV construction and plan any chamber connections.
Control
Include the controller, software interface and number of axes.
Your questions
Frequently asked questions
Does 2 nm resolution mean 2 nm positioning accuracy?
No. The 2 nm figures describe sensor resolution and minimum incremental motion. Typical bidirectional repeatability is ±200 nm over full travel. Assess the complete mechanism against your positioning requirement.
What is a PZT actuator?
PZT means lead zirconate titanate, a piezoelectric ceramic used in many actuators. The term identifies a material; travel, force and positioning behavior also depend on the actuator’s drive design and feedback.
Is blocking force the same as holding force?
For a piezo stack, blocking force is the force generated when expansion is fully prevented. GO specifications distinguish operating force during motion from holding force with power off: both are at least 10 N.
Can I motorize an existing mirror mount?
Yes, where the mounting interface, available space, stroke and contact geometry are compatible. GO actuators provide a 9.5 mm clamping shank or M9 thread; share your mount drawing with us to assess the fit.
Which version should I choose for vertical motion?
Both versions provide the same operating-force and loaded-speed specifications. Choose according to the operating environment, then match the actuator to your mechanism’s force requirement.
