NAC2121-Hxx (Replaces SCMAR01)
Noliac Ring Actuator Stack
NAC2121 is one of Noliac's ring actuators, which can be stacked according to customers' needs. The ring stacks are typically used when a medium displacement at high force is required. Noliac's ring 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 ring stacks are manufactured with ceramic layer thickness down to 20µm as standard in order to allow very low operating voltage for full performance of the piezo material. Noliac's ring stacks are mostly made to customer specifications, but a wide range of parts is available from stock as well.
