Newport MKS Piezo Stack Actuator, 0.025 mm Travel Range, Open-loop NPA25

The NPA25 Nano-Positioning Piezo Stack Actuator is ideally suited for integration into custom motion devices. It provides nanometer resolution over a 25 μm travel range with micro-second response time in a very compact housing. NPA series actuators can generate large forces up to 1000 N which makes them particularly useful for machine tools, active vibration isolation or adaptive mechanics. Their small size and high resonant frequency are suitable for scanning microscopy, laser tuning and beam steering, patch clamping or micro lithography applications. In this open-loop version, the resolution is only limited by the noise of the control electronics, but repeatability and stability are compromised due to the hysteresis and creep of the piezo ceramic material. Fastening is accomplished by M3-threads at the top and the base of the piezoelectric actuator. Like all piezoelectric devices, moment loads and side forces should be avoided. Spanner flats are provided and should be used when securing screws. Use with the NPC3 Nanopositioning Amplifier.
