      光電開關是脈沖調制由振蕩電路產生的,它是由發光二極管發出的GL。當被測量的物體進入光的范圍內時,光脈沖被反射回光敏晶體管。在接收電路中,光脈沖是脈沖信號,然后通過選擇放大器進行放大和同步。然后利用數字積分或鋼筋混凝土積分消除干擾。
      Photoelectric switch is generated by pulse modulation by oscillating circuit. It is GL emitted by light emitting diode. When the measured object enters the range of light, the light pulse is reflected back to the phototransistor. In the receiving circuit, the optical pulse is a pulse signal, which is amplified and synchronized by selecting an amplifier. Then the interference is eliminated by using digital integral or reinforced concrete integral.
      光電開關一般具有良好的回差特性,所以即使檢測到的對象在小范圍內的驅動不會影響輸出狀態,所以它可以保持在穩定工作區。同時,自診斷系統還可以顯示光狀態和穩定的工作區域,以保持光電開關的工作。
      Photoelectric switches generally have good backlash characteristics, so even if the detected object is driven in a small range, it will not affect the output state, so it can be maintained in a stable working area. At the same time, the self-diagnosis system can also display the light state and stable working area to keep the photoelectric switch working.
