April 2015, Auburn, MA -- Physik Instrumente released its catalog on PiezoMike high-precision miniaturized opto-mechanical piezo-motor actuators.

N-472 closed-loop PiezoMike actuator adds position feedback in a compact package, very similar to its N-470, open-loop sibling.  Both actuators are based on a screw and ratchet mechanism, where a small piezo ceramic block performs the individual “clicks” based on the input to a controller.

Step size and frequency are variable and allow the user to control the desired speed and positioning resolution. The position sensor resolution of the new N-472 actuator is below one nanometer. PiezoMike products simplify the automated adjusent of mechanical and opto-mechanical components. Motion ranges from 7.5mm to 26mm are standard, as well as vacuum capability.

The advantage of the piezo ratchet design is a very high stiffness and blocking force of 100N (22 lbs). Once a position is reached, the actuator is vibration-proof, shock-resistant, and long-term stable, with no position drift or jitter.

PiezoMike actuators have a lifetime of more than a billion steps, are self-locking, require no holding current, and generate no heat at rest. PI can easily modify existing designs or completely customize piezo devices to fit the exact requirements of the application.

Applications include laser-systems, photonics alignment, micromanipulation, biotechnology, cell manipulation, medical technology, and lab automation.
