对射光电开关需要注意的事项

  对射光电开关的工作原理是通过阻挡和传导红外发射光并引起红外接收管中的电流变化来实现开闭判断,其发射器和接收器分别位于U形槽的两侧,并形成光轴。当检测到的物体通过U形槽并阻挡光线时,光电开关产生检测到的切换信号,上海定宸传感器对于检测高速变化和区分透明和半透明物体是相对安全可靠的。

  一、耐高温接近开关选择有三个主要因素:

  1、槽的宽度:待检测物体通过槽光耦插槽,以实现红外光的阻挡,接近开关的槽宽应比检测物体宽,并有一定的余量,易于安装,

  选择电感式模拟量传感器河南快3的外部电路时,首先确定负载电阻,然后根据转换效率选择红外发射器的电流,被测物体的移动速度越快,红外接收管的负载电阻应该越小。
