Piezoelectric Bending Transducer (D220-H4BR-2513YB) Model:D220-H4BR-2513YB only motion along one axis

only motion along one axis is utilized

When an electric field having the same polarity and orientation as the original polarization field is placed across the thickness of a single layer disk

If an electric field is applied which makes the element thinner

2-Layer Bender with Standard Mounting

Thin vacuum sputtered nickel electrodes produce extremely low current leakage and low magnetic permeability

Piezoelectric Bending Transducer (D220-H4BR-2513YB) Model:D220-H4BR-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.
