絕對值旋轉編碼器為每個軸位置提供一個唯一編碼的數值。特別是在定位任務中,絕對值編碼器可減輕控制器的計算任務,並通過消除對額外輸入組件的需求來降低成本。
此外,由於目前位置值直接可用,在機器接通時或電源故障後,無需再執行參考操作。並行絕對值編碼器通過多條並行線,將位置值傳輸到分析電子裝置。串列絕對值編碼器通過標準化介面和協議,傳輸其輸出資料。
過去,通常要為串列資料傳輸建立點對點連接,但現在現場總線系統的使用頻率更高。

Pepperl+Fuchs 旋轉編碼器產品組合涵蓋了目前市場上絕對值編碼器所使用的最豐富的介面。
Constant shock and vibration, high bearing loads, dirt and temperature fluctuations—the heavy-duty absolute rotary encoders from Pepperl+Fuchs are ideally suited for extreme environments. On cranes, excavators or lifting systems, the compact sensors impress with maximum reliability, even under the most adverse conditions.
Pepperl+Fuchs 的旋轉編碼器具有兩種不同的防點火保護。這兩種防點火保護的區別之處在於,一種為「防火外殼」(EEx d),另一種為「固有安全」(EEx i) 保護。
