Piezoelectric Bending Transducer (Q220-A4BR-2513YB) Model:Q220-A4BR-2513YB only motion along one axis

only motion along one axis is utilized

the piece expands along the axis of polarization (thickness direction) and contracts perpendicular to the axis of polarization (length and width direction)

is typical

PSI-5A4E is an industry type 5A (Navy Type II) piezoceramic

Piezoelectric Bending Transducer (Q220-A4BR-2513YB) Model:Q220-A4BR-2513YB only motion along one axisA 2 layer piezoelectric actuator produces curvature when one piezo layer expands while the other layer contracts. These transducers are often referred to as benders, bimorphs, or flexural elements. Bender motion on the order of hundreds to thousands of microns, and bender force from tens to hundreds of grams, is typical. The brass shim reinforcement laminated between the two piezoelectric layers is an economical approach to producing a rugged actuator.
