Piezoelectric Extending Transducer (T220-A4BR-1305YE) Model:T220-A4BR-1305YE Due to its smaller size

Due to its smaller size and good performance this is a popular product for many applications

It has high motion per volt sensitivity but its upper temperature range is limited and its properties are more sensitive to temperature

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

A 1-layer piezoelectric actuator produces curvature when one piezo layer expands while the other layer contracts

Piezoelectric Extending Transducer (T220-A4BR-1305YE) Model:T220-A4BR-1305YE Due to its smaller sizeA 2 layer element behaves like a single layer when both layers expand (or contract) together. If an electric field is applied which makes the element thinner, extension along the length and width results. Typically, only motion along one axis is utilized. Extender motion on the order of microns to tens of microns, and force from tens to hundreds of Newtons is typical.
