P-871 piezoelectric transducers are unique closed-loop piezo bender actuators based on the open-loop PL122 to PL140 PICMA®-series multilayer actuators. Equipped with high-resolution position feedback sensors they provide much better linearity, accuracy and repeatability than open loop piezo benders.
Long Lifetime and High Performance
PICMA® piezoelectric bender actuators are superior to conventional actuators in high-endurance situations. They show substantially longer lifetimes both in static and dynamic operation, even in harsh environments. The monolithic, ceramic-insulated design makes polymer-film insulation unnecessary. Diffusion of water molecules into the insulation layer, the major cause of dielectric breakdown, is greatly reduced by the use of cofired, outer ceramic insulation.
