Piezoelectric Translators (PZTs)

Click here for Piezo ActuatorSelection Guide

Piezoelectric Translators are solid state (ceramic) actuators that directly convert electrical energy into motion (mechanical energy).

Advantages:

• Sub-nanometer resolution.
• Zero stiction/friction.
• Zero backlash.
• Very high stiffness (up to 2,000,000 N/mm for 20 µm actuator).
• No wear & tear.
• Fast response (sub-millisecond).

Application examples: Micropositioning, Laser Cavity Tuning, Mask Positioning, Fiber Optic Positioning, Semiconductor Test Equipment, Adaptive Optics, Precision Machining/Diamond Turning, Biomedical Engineering, Active Vibration Cancellation, Smart Structures, Force Generation.

• Closed loop operation for highest accuracy, linearity and repeatability.
• Widest range, highest quality of piezo actuators world-wide (›10,000 different piezo configurations).
• All manufacturing steps from the PZT powder to the finished product are controlled by PI.
• Variety of stacked PZT translators with typical displacement range 5 to 200 µm (up to 0.008 inches).
• Low Voltage (100 V) and High Voltage (1000 V) versions.
• Multi-layer technology (co-fired).
• Ultra high vacuum, low temperature and high temperature options.
• Threaded tip, flat tip and ball tip options.
• Bimorph bending actuators and lever amplified translators for motion up to 1 mm.
• Standard, custom and OEM control electronics (digital and analog controllers, rack mount and modular systems, compatibility with advanced feed-forward techniques), software.
• OEM and custom designs.
