High Accurancy Bimorph Actuator
Piezoelectric ActuatorsBimorph actuators are made from a sandwiched pair of piezoelectric elements which can expand and contract in length. When used as a sensor,bending causes one side to go into tension and the other into compression, and having a response frequency in the audible range permits the bimorph element to be used as a high sensitivity sound sensor. When used as an actuator, an electrical input results in a bending force which can be used as a switching element in a wide range of applications.Normal Model: ( special dimensions can be customized) TypeLengthWidthThicknessFree lengthVoltageDeflectionForce（mm）（mm）（mm）（mm）（DC V）（mm）（mN）QDA60×20×0.760200.750150≥2.6≥450QDA60×10×0.760100.750150≥2.6≥250QDA49×2.1×0.8492.10.838200≥1.6≥110QDA47.5×4.4×0.7547.54.40.7537200≥1.6≥200QDA 47.4×2.0×0.7847.420.7837200≥1.5≥120QDA45×10×0.745100.735150≥1.5≥350QDA45×6.5×0.7456.50.735150≥1.5≥250QDA40×20×0.740200.730150≥1.1≥600QDA40×12×0.740120.730150≥1.1≥450QDA40×10×0.740100.730150≥1.1≥350QDA35×2.5×0.7352.50.725200≥1.1≥160QDA 36×2.1×0.7362.10.725200≥1.1≥140Piezoelectric Actuators Used in Braille Devices Below items can be used in braille devices: TypeLengthWidthThicknessFree lengthVoltageDeflectionForce（mm）（mm）（mm）（mm）（DC V）（mm）（mN）QDA49×2.1×0.8492.10.838200≥1.6≥110QDA 47.4×2.0×0.7847.420.7837200≥1.5≥120QDA35×2.5×0.7352.50.725200≥1.1≥160QDA 36×2.1×0.7362.10.725200≥1.1≥140Piezoelectric Actuators Used in Control of Gas Control ValvesMain features:● Without heating phenomenon existed in solenoid valves● Without electromagnetic interference● Small size, light weight● High dynamic, response time of only 2ms● Without mechanical wear, long life, working times of up to two billion times● Ultra-low power consumption of only 1mW, can be battery and solar-powered● switching characteristics, enables digital control and PWM regulator● proportion features, achieves linear regulator
