NAC2125 (Replaces CMAR05)

Noliac Ring Actuators

NAC2125 is one of Noliac's ring actuators, which are typically used when a low displacement at high force is required. Noliac's ring actuators are cofired monolithic piezoelectric low voltage actuators that convert an electrical input to a very high-resolution linear movement at high force.

Noliac's ring actuators 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 actuators are mostly made to customer specifications, but a wide range of parts is available from stock as well.
