Noliac Plate Actuator Stack
NAC2001 is one of Noliac's plate actuators, which can be stacked according to customers' needs. Noliac's plate stacks are typically used when a medium displacement at high force is required. Noliac's plate stacks are stacks of cofired monolithic piezoelectric low voltage actuators that convert an electrical input to a very high-resolution linear movement at high force.
Noliac's plates are manufactured with ceramic layer thickness down to 20 µm as standard in order to allow very low operating voltage for full performance of the piezo material. Noliac's plate stacks are mostly made to customer specifications, but a wide range of parts is available from stock as well.
