PI (Physik Instrumente) L.P. PiezoMike Linear Actuators N-472

High stability and Holding force >100 N Self-locking at rest even when closed-loop control is switched off Travel range 7.5 mm and 13 mm Compact design with integrated incremental encoder Encoder resolution to <1 nm, 50 nm minimum incremental motion Feed force 22 N Lifetime > 1,000,000,000 steps Versions with cable exit offset by 180° Nonmagnetic and vacuum-compatible functional principle PIShift Piezo motors Compact, low-cost inertia drive principle (stick-slip). When at rest, the drive is self-locking, requires no current and generates no heat. It holds the position with maximum force Integrated Position Sensor An incremental encoder measures the motion performed relative to a freely definable reference position. In combination with the E-871 motion controller, the encoder resolution is up to <1 nm Alignment of Mechanical and Optomechanical Components Stable alignment of optical paths. Long-term positioning stability: High stability in target position, reliable start-up 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
