ELTRA編碼器產品分類及應用
Eltra已經(jīng)開發(fā)諸多類型的增量編碼器：各種機械安裝方式（實心軸、盲孔軸、通孔軸），各種分辨率、安裝法蘭方式、電路輸出方式，以各種應用需要。
除了提供標準產品，Eltra也提供產品定制服務，以滿足客戶的特殊需求，給予客戶360度服務。
旋轉編碼器是一種結合光學、電子、機械技術的產品。它用來反饋旋轉軸的位置和速度。
增量旋轉編碼器的定義源自于其工作原理：它能檢測從參考點實際點的增加量，和旋轉方向。增量編碼器可通過內部的輸出電路輸出的脈沖信號感知旋轉的角度、角速度、角加速度。但是，每次開機需要恢復系統(tǒng)零位。
Eltra易爾創(chuàng)編碼器在定位方面明顯地優(yōu)于增量式編碼器，已經(jīng)越來越多地應用于工控定位中。型編碼器因其高精度，輸出位數(shù)較多，如仍用并行輸出，其每一位輸出信號必須確保連接很好，對于較復雜工況還要隔離，連接電纜芯數(shù)多，由此帶來諸多不便和降低可靠性，因此，編碼器在多位數(shù)輸出型，一般均選用串行輸出或總線型輸出，德國生產的型編碼器串行輸出zui常用的是SSI（同步串行輸出）。
多圈式編碼器。編碼器生產廠家運用鐘表齒輪機械的原理，當中心碼盤旋轉時，通過齒輪傳動另一組碼盤（或多組齒輪，多組碼盤），在單圈編碼的基礎上再增加圈數(shù)的編碼，以擴大編碼器的測量范圍，這樣的編碼器就稱為多圈式編碼器，它同樣是由機械位置確定編碼，每個位置編碼*不重復，而無需記憶。多圈編碼器另一個優(yōu)點是由于測量范圍大，實際使用往往富裕較多，這樣在安裝時不必要費勁找零點，將某一中間位置作為起始點就可以了，而大大簡化了安裝調試難度。多圈式編碼器在長度定位方面的優(yōu)勢明顯，已經(jīng)越來越多地應用于工控定位中。
