MARS Rover-proven piezo drive technology is behind PI's new high-speed nanopositioning system. The P-630 linear stage achieves its high performance through a direct-drive mechanism and multi-layer piezo ceramic actuators. Its high mechanical resonant frequency of 3.25 kHz enables very rapid scanning speeds and step and settling times of only a few milliseconds.
The compact closed-loop piezo positioner provides 80 microns of motion with sub-nanometer resolution. With a height of 0.7" and width of 2 inches, the device integrates a large aperture of 1.2" an advantage for optical applications.

The drive technology of the highly dynamic piezo nanopositioning systems is based on all-ceramic insulated PICMA® piezo actuators. They were tested by NASA for 100 billion cycles without failure.
Extremely high accuracy and stability in the nanometer and sub-nanometer realm is achieved by an integrated capacitance sensor and closed-loop operation with a digital servo piezo controller.
For high performance control, PI's new E-709.CHG piezo motion controller is available. Its digital control algorithms provide better linearity than conventional piezo controllers and all motion parameters can be adjusted on the fly.

Model TR1 Tru-Trac
The Model TR1 Tru-Trac® linear measurement solution is a versatile option for tracking velocity, position, or distance over a wide variety of surfaces. An integrated encoder, measuring wheel, and spring-loaded torsion arm in one, compact unit, the Model TR1 is easy to install. The spring-loaded torsion arm offers adjustable torsion load, allowing the Model TR1 to be mounted in almost any orientation - even upside-down. The threaded shaft on the pivot axis is field reversible, providing mounting access from either side. With operating speeds up to 3000 feet per minute, a wide variety of configuration options - including multiple wheel material options - and a housing made from a durable, conductive composite material that minimizes static buildup, the Model TR1 Tru-Trac® is the ideal solution for countless applications.
