Description: A 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.

Non-magnetic extension actuators are fabricated using piezoceramic with non-magnetic electrodes and non-magnetic reinforcing materials. They exhibit no magnetic permeability and generate no external magnetic field. Performance is similar to standard brass shim elements of similar size and thickness but capacitance, deflection and force are reduced by ~ 5%. They are suitable for cryogenic and vacuum use.

Standard Sizes: Designated "-103", "-203", and "-303" size"
