PI (Physik Instrumente) LP offers the P-871 closed-loop piezo bender actuator series. These unique long-travel piezo transducers are based on PI’s ceramic-encapsulated Picma series multilayer actuators.

The integrated high-resolution position feedback sensor provides up to 20 times better linearity, accuracy and repeatability than other open-loop piezo benders on the market. The P-871 bender actuators also achieve longer positioning ranges than other closed-loop piezo actuators, up to 1600 µm (1.6 mm), and response times in the millisecond range. (In open-loop mode, 2-mm travel is possible).

Picma bender actuators are superior to conventional actuators in high-endurance situations. They show substantially longer lifetimes both in static and dynamic operation, even in harsh environments. The monolithic, ceramic-insulated design makes polymer-film insulation unnecessary. Diffusion of water molecules into the insulation layer, the major cause of dielectric breakdown, is greatly reduced by the use of cofired outer ceramic insulation.

Typical applications include: scanning of optical components, beam deflection and stabilization, nanopositioning, wire bonding, fiber optic switches and alignment controllers. PI also offers the new E-651.1S and E-651.2S closed-loop controllers for operating the P-871 benders.

Features & Advantages:
  • Closed-loop operation for 20 times better accuracy and repeatability
  • Monolithic design for faster response and higher stiffness
  • Significantly lower operating voltage, only +/- 30 V (3 to 10 times lower than conventional piezo benders)
  • Ceramic insulation for extended lifetime (insensitive to water molecules)
  • Ideal for scanning applications
  • Vacuum-compatible versions available
  • Increased dynamic performance and extra-wide temperature range to 300 ° F (150 °C)
  • 100 percent vacuum-compatible

GLOSSARY
actuator
Mechanical device intended for the translation (rotational and linear) using high precision control from electronically operated circuits. See linear actuator; rotary actuator.
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
