Piezoelectric Extending Transducer (T220-A4BR-1305YE) Model:T220-A4BR-1305YE the piece expands along the

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

This material provides a compromise between PZT 5A and 5H

These transducers are often referred to as benders

clamp conditions

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

Piezoelectric Extending Transducer (T220-A4BR-1305YE) Model:T220-A4BR-1305YE the piece expands along theA 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.
