OPB608C传感器变送器的光学传感器-反射式-模拟输出规格书PDF中文资料

OPB608C属于传感器变送器的光学传感器-反射式-模拟输出。由梯梯电子集成制造服务(苏州)有限公司制造生产的OPB608C光学传感器 - 反射式 - 模拟输出模拟输出反射式光学传感器产品族中的产品包含彼此相邻并朝向相同方向安装的光发射器和光敏元件（通常是光电晶体管），以便确保发射器发出的光在传感器视场中被物体反射时可以被设备内的传感元件检测到。这种类型的模拟输出传感器以最少的处理量直接传送由光电传感器产生的信号，同时用户需要提供自己的解释机制来确定物体检测结果。

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.
