2015年11月16日——Queensgate公司NPC-D-5200是一款用于與該公司非常先進的閉環壓電執行器和工作臺配合使用的數字控制器；它在動態性能和精度上提供了新基準。Queensgate 率先在閉環中使用電容式傳感器來提供精確的位置反饋；NPC-D-520集成了精確的電容測量電路，并以120,000次/秒的速度更新工作臺位置，因此提供了高速高位置精度。它能夠滿足許多高要求的校準和計量應用。通過采用專利低噪聲技術，工作臺位置噪聲得到了降低，因此在大多數實現中它只有幾十pm。 

       NPC-D-5200控制器具有緊湊（268mm×194mm×70mm）、輕量（1.7kg）的結構。它集成了串行（RS232）、USB2.0和以太網接口，因此連接選擇不受限制，并且系統靈活性得到了最大化。該器件具有覆蓋10℃至40℃的工作溫度范圍。
