DATASHEET MPO-Specification.pdf

Description

MPO show the following outstanding properties:

  • Large strain of ca. 1.5‰ at 0 to 150 V
  • >2‰strain in the extended voltage-range of -45 to 180 V
  • Consequently laminated structure and monolithic sintering guarantee best possible dimensional tolerances and straightness of motion
  • Avoiding of micro-cracks and the pillow-effect at simultaneous insulation-safety is achieved by µm-precise definition of the electrodes (drawn back) in combination with an elastic isolation
