日本一家公司向市场投放了3个类型6个品种的光电传感器,即OS5501激励型光电传感器、OS2202反射型光电传感器和OS3601、3501、3401、3301光电断续器。OS5501是将红外发光二极管和高灵敏度光电晶体管组装在传感器部分、使之与激励器成为一体的光电传感器。其特点有:①由于传感器部分与可动部分构成一体,能提高检测效果,②这种结构不受外界干扰光的影响,③激励器部分的工作转矩小,能检测诸如纸屑等轻物体的移动。
A Japanese company put on the market three types of 6 varieties of photoelectric sensors, namely OS5501 excitation photoelectric sensor, OS2202 reflective photoelectric sensor and OS3601,3501,3401,3301 photo interrupter. OS5501 is the infrared light-emitting diodes and high-sensitivity phototransistor installed in the sensor part, so that it integrates with the actuator photoelectric sensor. Its features are: ① As part of the sensor and the movable part of the integration, can improve the detection effect, ② This structure is not affected by external interference light, ③ actuator part of the small working torque, can detect such as paper and other light objects Move.
