| | | P-842, P-843, P-844 and P-845 series piezo translators are high-resolution linear actuators for static and dynamic applications. They provide sub-millisecond response and sub-nanometer resolution. Design These actuators consist of a friction-free, preloaded, monolithic multilayer piezoceramic stack protected by a stainless steel case. The high preload gives these actuators outstanding properties for dynamic applications (e.g. precision machining, active damping, etc.) and push-pull applications. Mounting Mounting is at the foot, although with push/pull forces of less than 100 N, the industrial actuator | | can be held by clamping the case. The P-176.50 / P-176.60 flexible tips can be installed to decouple the ceramic from bending forces (see page 1-45). For more mounting guidelines, see page 1-48. High Accuracy in Closed-Loop Operation The P-842 and P-844 are designed for open-loop positioning tasks. The P-843 and P-845 versions are equipped with integrated high-resolution SGS industrial position sensors and offer high-accuracy, closed-loop operation (for more information, see the "Tutorial: Piezo-electrics in Positioning," Section 4). Options: P-703.20 High-vacuum option, p. 1-44. | | |
