光电开关是传感器的一种,它把发射端和接收端之间光的强弱变化转化为电流的变化以达到探测的目的。由于光电开关输出回路和输入回路是电隔离的(即电缘绝),所以它可以在许多场合得到应用。光电开关已被用作物位检测、液位控制、产品计数、宽度判别、速度检测、定长剪切、孔洞识别、信号延时、自动门传感、色标检出、冲床和剪切机以及安全防护等诸多领域。此外,利用红外线的隐蔽性,还可在银行、仓库、商店、办公室以及其它需要的场合作为防盗警戒之用。
此外,光电传感器的结构元件中还有发射板和光导纤维。角反射板是结构牢固的发射装置,它由很小的三角锥体反射材料组成,能够使光束准确地从反射板中返回。它可以在与光轴0到25的范围改变发射角,使光束几乎是从一根发射线,经过反射后,仍从这根反射线返回。
对射型:对射型光电开关由发射器和接收器组成,结构上是两者相互分离的,在光束被中断的情况下会产生一个开关信号变化,典型的方式是位于同一轴线上的光电开关可以相互分开达50米。特征:(1)辨别不透明的反光物体;(2)有效距离大,因为光束跨越感应距离的时间仅一次;(3)不易受干扰,可以可靠合适的使用在野外或者有灰尘的环境中;(4)装置的消耗高,两个单元都必须敷设电缆。
