| | | P-242, P-243, P-246 and P-247 are preloaded, high-load piezo actuators for static and dynamic applications. They provide sub-millisecond response and sub-nanometer resolution. Design The P-246.xx, P-247.xx, P-242.30, P-243.30, P-242.40 | | and P-243.40 models come with a stainless steel case with integrated, frictionless preload. The other models come with an aluminum case, stainless steel end pieces and spring bolts providing the preload. The high load capacity and internal spring preload makes them ideal for machining applications and active vibration cancellation. The ceramic layers in the P-246 and P-247 models are double in number and thinner than those in the P-242 / P-243 models, thus providing larger travel ranges in the same size package. For maximum lifetime, voltages in excess of 750 V should be applied only for short durations. High Accuracy in Closed-Loop Operation The standard models are designed for open-loop opera- | | |
