Piezo specialist PI's flexure-based piezo actuators such as the P-601 series provide up to ten times larger travel ranges than classical piezo stack actuators a in low profile package, with virtually unlimited resolution and lifetime.
The stiff construction allows for fast response with rise times much shorter than one millisecond. The design involves no friction, no lubricants and no wear. Because of the many advantages over motor/leadscrew-driven positioners, more and more flexure actuators are used in fast-valve actuation mechanisms, and for other precision positioning tasks, ranging from automotive to data storage and biotech applications.
Piezo flexure actuators require no lubricants, and if ceramic encapsulated piezo ceramics are used (no outgassing/high bakeout temperatures) they are ideal for ultra-high-vacuum applications. Non magnetic designs are also available.
Typical applications include high-speed valve control, photonics, clean room micro-manufacturing, laser and spectrometer tuning, medical instrumentation, nanotechnology, auto focus, high throughput screening, and micro-dispensing.
