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 several microns, and force from tens 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 ~ 15%. They are suitable
for cryogenic and vacuum use.
Soldering wires to piezoceramic and/or the center shim can be
difficult without the proper solder and flux. Our kit will get you started with everything you need, plus information on ordering
larger quantities directly from the manufacturer.
