Component piezoceramic BBPXST-DC

Product overview
BBPXST-DC is a disc multilayer piezoelectric ceramic actuator that generates axial micromovement when a drive voltage is applied. It is designed for applications requiring controlled displacement and high blocking force in a compact form factor.

Construction and options

• Alternate ceramic layers with internal electrodes produce axial motion; side termination electrodes connect the internal electrodes while the other faces are ceramic-insulated.
• A cross mark on the side identifies positive polarity. Dimensions and drive voltage can be customized to application requirements.

Use and selection

• Each listed row corresponds to one configuration; select the configuration considering required voltage, displacement, operating frequency and generated force together.
• Actual displacement depends on applied voltage, mechanical load and mounting conditions. Avoid impact, bending and localized stress during assembly.
• For use in vacuum or special environments, verify suitability of leads, bonding materials and encapsulation before selection.
