Inertia drive
Compact, inexpensive inertia drive principle (stick-slip). At rest, the drive is self-locking, 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 alignment of optical paths. Long-term positioning stability: 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: 20 N preload, measured over the entire stroke, compensated for temperature drift.
Unidirectional repeatability / minimum incremental motion: 20 N preload, measured at 100 µm 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.
