OPB608C傳感器變送器的光學傳感器-反射式-模擬輸出規(guī)格書PDF中文資料

OPB608C屬于傳感器變送器的光學傳感器-反射式-模擬輸出。由梯梯電子集成制造服務(蘇州)有限公司制造生產的OPB608C光學傳感器 - 反射式 - 模擬輸出模擬輸出反射式光學傳感器產品族中的產品包含彼此相鄰并朝向相同方向安裝的光發(fā)射器和光敏元件（通常是光電晶體管），以便確保發(fā)射器發(fā)出的光在傳感器視場中被物體反射時可以被設備內的傳感元件檢測到。這種類型的模擬輸出傳感器以最少的處理量直接傳送由光電傳感器產生的信號，同時用戶需要提供自己的解釋機制來確定物體檢測結果。

Description:

OPB608 reflective switches consist of an infrared emitting device (LED or VCSEL) and a NPN silicon phototransistor mounted “sideby-side” on a parallel axis in a black opaque plastic housing. All OPB608’s (except OPB608R) have an emitting device and a phototransistor that are encapsulated in a visible filtering epoxy. The phototransistor responds to radiation from the emitter only when a reflective object passes within its field of view. The phototransistor has enhanced low current roll-off to improve the contrast ratio and immunity to background irradiance. LED versions are designed for near-field applications. The VCSEL version is designed for longer distances.
