They provide sub-millisecond response and sub-nanometer resolution. These translators consist of highly reliable multilayer PZT ceramics stacks operating in a voltage range of 0 to 100V. The stacks are covered with epoxy insulation and heat shrink tube for protection and strain relief of the wire leads. Due to their high resonant frequency, they are ideal for dynamic operation with small loads. For dynamic operation with larger loads, an external preload is recommended. PI offers a variety of preloaded translators for applications with larger tensile forces (see following pages). Care must be taken during mounting (e.g. with epoxy) and operation, because the translators are not protected by a case or preload (see mounting guidelines see link). Accessories Extension cables & connectors: see link in the "PZT Control Electronics" section.
