Inertia drive
Compact, inexpensive inertia drive principle (stick-slip). The drive is self-locking at rest, requires no current, and does not generate any heat. It holds the position with maximum force.
Integrated position sensor
An incremental encoder measures the relative motion to a freely definable reference position.
Alignment of mechanical and optomechanical components
Stable adjustment in optical paths. Long-term positioning: High stability at target position, reliable startup even after longer downtimes. High holding force and resolution by combining piezo actuators with mechanical thread translation. Vacuum-compatible versions to 10-6 hPa available.

Maximum velocity not suitable for continuous operation (refer to the user manual).
Linearity error: 22 N preload, measured over the entire stroke, compensated for temperature drift.
Unidirectional repeatability: 22 N preload, measured at 1 mm stroke, compensated for temperature drift.
Cable length of vacuum-compatible models: 1 m connecting cable on the actuator, with stranded wires on the cable end; 2 m separate connecting cable, D-sub 15 (m) to stranded wires.
Custom versions are available on request.
At PI, technical data is specified at 22 ±3 °C. Unless otherwise stated, the values are for unloaded conditions. Some properties are interdependent. The designation "typ." indicates a statistical average for a property; it does not indicate a guaranteed value for every product supplied. During the final inspection of a product, only selected properties are analyzed, not all. Please note that some product characteristics may deteriorate with increasing operating time.
