15 µm ± 10% Maximum Displacement
6.5 x 6.5 x 18 mm Package
This low-voltage actuator transforms electrical energy into precisely controlled mechanical displacements. The maximum displacement of 15 µm is achieved at the maximum input voltage (100 V). When mounting, avoid bending forces by centering the mechanical load on the piezoelectric end faces. If the actuator is incorporated into a design that calls for a preload, it is recommended that the preload not exceed 95 lbs.
Fast Response Time: 1/3 Resonant Frequency
Resonant Frequency up to 261 kHz (AE0203D04F)
These piezoelectric actuators transform electrical energy into precisely controlled mechanical displacements. They are ideal for applications requiring rapid, precise positional changes on the nanometer or micrometer scale. A room-temperature epoxy, such as Thorlabs' F120, is the recommended method for making connections to these piezoelectric stacks. When mounting, avoid bending forces and center the mechanical load on the piezoelectric end faces. If the actuator is incorporated into a design that calls for a preload, it is recommended that the preload not exceed 50% of the specified clamping force, which is 45 lbs for the AE0203 models and 190 lbs for the AE0505 models.
Enables Closed-Loop Operation
Wheatstone Bridge Configuration Eliminates Thermal Variances in Strain Gauge Resistance
The PZS001 is an AE0505D16F piezoelectric actuator with an attached full bridge strain gauge. The full bridge strain gauge is made by connecting four metallic strain gauges in a Wheatstone bridge configuration. Each individual strain gauge has a resistance of 350 ohm and a gauge factor of two. The feedback from the strain gauge is used by the controller to provide linear operation of the piezo-electric actuator. In order to use a strain gauge reader like the TSG001 to monitor the feedback, the strain gauge must first be connected to a pre-amplification circuit like the AMP002 listed below.
The smaller diameter red lead and the black lead are used to supply the input voltage to the strain gauge. The blue and yellow wires are used to monitor the output voltage of the strain gauge.

M12 x 1.25 Threaded Housing
BNC Controller Connector
The TLK-PZT1 is an AE0505D08F piezo actuator in a M12 x 1.25 threaded mount. Although it has been designed for use with our Tunable Laser Kits, its housing allows it to be integrated into a number of applications.
The AMP002 is a pre-amplification circuit for full bridge strain gauges that also features a removable cover. The printed circuit board measures 1.6" x 2.25" (41 mm x 57 mm) and has four solder points for the full bridge strain gauge leads and a 9-pin D-type connector for connecting to a strain gauge reader. The cable required to connect the circuit to the TSG001 stand-alone strain gauge reader or the BPC Series of controllers is also included. The circuit contains two resistive pots, one to continuously vary the circuit's gain from 1 to 10,000 and the other to apply a DC offset that can be used to balance the full bridge strain gauge. This unit provides the required input voltage to the strain gauge circuit when connected to a Thorlabs strain gauge reader.
