壓電陶瓷芯片 | PCh 150 / HPCh 150
PCh 150 / HPCh 150壓電（diàn）陶瓷（cí）芯（xīn）片多層壓電陶瓷組成最大推力可高達10000N，這些驅動器可以精密移動，產生的（de）自由（yóu）行程範圍(無負載條件（jiàn）下)從2 µm至4 µm 。驅動器預載最大位移（yí）負載（zǎi）時（shí），可（kě）以達到最大（dà）位移，每種型號對於這點都有相應規定。每種型號最大（dà）位移的實際值有所差異，必須通過實驗確定，最大位移始終會大於自由行程位移。

tolerances:
a, b +/- 0.3 mm
L +/- 0.1 mm
Fig. : Piezo-chips PCh, PHCh
Mounting advises: Piezo-chips show very small stroke rates due to their short active length L.
Incorrect mounting will impact force and stroke generation, leading to insufficient performance and unwanted bending and tilting. Please follow instructions in chapter 2.3.
