Linear piezoelectric actuator BBPXST-PH

101 V...300 Vmultilayer

Product overview
BBPXST-PH is a multilayer piezoelectric actuator using alternating ceramic layers and internal electrodes to generate axial micromovements when a drive voltage is applied. It features a square body with a central bore for mechanical integration.

Construction and options

• Side termination electrodes connect the internal electrodes; remaining sides are ceramic-insulated.
• A cross mark on the side identifies the positive polarity.
• Dimensions and drive voltage can be customized to application requirements.

Use and selection

• Each line corresponds to a specific configuration. Choose drive voltage, nominal displacement, operating frequency and required force together.
• Actual displacement depends on drive voltage, mechanical load and mounting conditions. Avoid impact, bending and concentrated stresses during assembly.
• For vacuum or special environments, confirm suitability of leads, bonding and encapsulation materials.
