Piezo Mike Linear Actuators

Product catalog summary

Overview: The document provides comprehensive details on the PiezoMike Linear Actuators and PIShift Piezomotors, emphasizing their high-resolution positioning, stability, and vacuum compatibility. It covers technical specifications, mechanical properties, drive properties, and recommended usage conditions.

Specifications: The N-470 series actuators offer a holding force greater than 100 N, a step size of 20 nm, and a travel range from 7.4 mm to 26 mm. They are compact, can withstand over 1 billion steps, and are available with different mounting options. The actuators are vacuum-compatible up to 10^-9 hPa.

Mechanical and Optical Alignment: These actuators ensure stable alignment for optical paths and long-term positioning stability, suitable for sensitive environments.

Drive Properties: Operating with a maximum voltage of 80 V and power consumption of 6.4 W, the actuators are compatible with E-870 PIShift drive electronics.

Closed-Loop Operation: The N-472 series includes an integrated position sensor for closed-loop operation, offering high stability and a holding force greater than 100 N. The encoder resolution can reach less than 1 nm, and they are nonmagnetic and vacuum-compatible up to 10^-6 hPa.

Kinematic Mirror Mounts: The N-480 series is designed for optics with diameters of 0.5", 1", or 2", offering high stability and a step size of 1 µrad, vacuum-compatible up to 10^-6 hPa.

Materials and Construction: Constructed with stainless steel screws and aluminum cases, ensuring durability and reliability.

Operational Guidelines: The maximum operating frequency is 2 kHz, with specific duty cycle recommendations to prevent overheating. The step size remains above 70% of the initial size over a lifetime of more than 1 billion steps.

PIShift Drive Electronics: Supports one to four axes with serial control, suitable for OEM applications. Interfaces include USB and optional SPI, with configurable piezo voltage from 0 to 100 V.

Applications: Suitable for industry and research applications, including optical alignment, micromanipulation, biotechnology, and medical technology.

Networkable Servo Controllers and Amplifiers: Designed for stick-slip piezo-motors and PIShift piezo inertia drives, with communication interfaces, power specifications, and control features detailed.

Control and Operation: Features a PID controller with on-the-fly parameter changes, analog encoder input, and optional manual control. Software support includes LabVIEW drivers and shared libraries for Windows and Linux.

Additional Features: Includes daisy-chain networking, internal safety circuitry, and a maximum power consumption of 35 W.

Contact Information: Lists contact details for PI's global offices, including locations in Germany, USA, Japan, and more.
