Plate Bender NAC2221 (replaces CMBP01)

Noliac/CTS Plate Bender

Noliac NAC222X's are typically used when a large displacement at low force is required. Noliac NAC222X's are cofired monolithic piezoelectric low voltage actuators that convert an electrical input to a very high-resolution bending movement at one end of a plate shaped actuator.

Noliac NAC222X's are manufactured with ceramic layer thickness down to 67µm as standard in order to facilitate very low operating voltage for full performance of the piezo material. A wide range of NAC222X bender actuators are available from stock.
