The NPA100SG Piezo Stack Actuator from Newport Corporation features a travel range of 100 µm and offers sub-nanometer positioning resolution, with an open-loop resolution of 0.2 nm. It is capable of generating forces up to 1000 N, making it suitable for applications requiring high load capacity such as machine tools and active vibration isolation. This actuator includes a strain-gauge position sensor for closed-loop operation, providing accurate and repeatable motion while compensating for actuator creep. The device is designed for use in both open and closed-loop control systems and is compatible with vacuum environments down to 10^-6 Torr. The actuator is compact and features M3-threaded fastening points for secure installation.
The NPA100SG Nano-Positioning Piezo Stack Actuator is ideally suited for integration into custom motion devices. It provides nanometer resolution over a 100 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. This closed-loop version features a high resolution strain-gauge position sensor for highly accurate and repeatable motion. Also, the position feedback compensates for actuator creep. The assembly is done as a full Wheatstone bridge and is temperature insensitive. The closed-loop devices can be used in either open or closed-loop control. 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.
