美國Piezotechnics 壓電堆棧

Multilayer piezo stacks. Low voltage type. Produced with co-fired manufacturing technique. Thin coating type.

美國Piezotechnics 壓電堆棧有多種形狀和尺寸,從1 x 1到25 x 25 mm2不等。它們由電并聯的堆疊壓電板組成。

Piezotechnics 壓電堆棧標稱工作電壓為0至150 V。這些致動器是“低壓壓電致動器”。Piezotechnics 壓電堆棧還允許具有高達30V至150V的擴展驅動器電壓范圍的半雙極操作。這種操作方法導致明顯更大的位移。

裸堆棧非常適合集成到自定義機制中。當與其他致動器類型(如在相同力下的液壓缸)相比時,壓電堆棧通常具有較小的尺寸。Alos接口非常簡單。壓電堆棧是長方體,并且具有兩根電線來控制元件。帶有預應力機構的封裝執行器是實現穩健系統集成的理想解決方案。

Piezotechnics 壓電堆棧可以在極端環境中運行。適用于在低溫、真空和外來環境(如高g場或振動)中操作。

有多種堆疊尺寸和選項可供選擇。共燒多層壓電堆的最大工作電壓為150V。該堆的特點是高功率密度,為您的應用提供強大、精確和快速的驅動。Piezotechnics 壓電堆棧允許在-30 V至150 V的電壓下進行半雙極操作。

Piezotechnics 壓電堆棧主要可選:低溫,真空,薄涂層,厚涂層,藍寶石半球,應變儀。

美國Piezotechnics 壓電堆棧標準型號如下,也可定制其他尺寸。
