Ring Bender 6 (CMBR06)
Noliac Ring Piezo Actuators
Noliac CMBR's are typically used when a medium displacement at medium force is required. Noliac CMB-Rs' are cofired monolithic piezoelectric low voltage actuators that convert an electrical input to a very high-resolution linear movement at the center of a ring/disc shaped actuator.
Noliac CMBR's are manufactured with ceramic layer thickness down to 20µm as standard in order to facilitate very low operating voltage for full performance of the piezo material. Noliac CMBR's are mostly made to customer specifications, but a wide range of parts is available from stock as well.
