The photoelectric switch is arranged in an elevator shaft, a leveling baffle is arranged at the leveling position of each layer in the elevator shaft, and the photoelectric switch is connected with a lift car in the elevator shaft and ascends and descends synchronously. The mounting frame comprises two oppositely arranged mounting arms and a connecting seat for connecting the two mounting arms, and a slide way for allowing the leveling baffle to penetrate through is formed between the two mounting arms; wherein an emission circuit board is arranged in one mounting arm, and a plurality of photoelectric emission tubes which are vertically arranged at intervals are arranged on the emission circuit board; a receiving circuit board is arranged in the other mounting arm, and a plurality of photoelectric receiving tubes which are vertically arranged at intervals are arranged on the receiving circuit board; and the photoelectric receiving tubes are used for receiving signals transmitted by the photoelectric transmitting tubes so as to detect the position change of the leveling baffle relative to the lift car. The detection accuracy of the photoelectric switch is improved, and the detection error is reduced.

    本发明公开一种光电开关及电梯,光电开关设置于电梯井道内,电梯井道内每层的平层位置处设有一平层挡板,光电开关与电梯井道内的轿厢连接并同步升降,其特征在于,光电开关包括安装架,安装架包括两个相对设置的安装臂和连接两个安装臂的连接座,两个安装臂之间形成用于供平层挡板穿过的滑道;其中,一个安装臂内具有发射电路板,发射电路板上设有多个竖向间隔排布的光电发射管;另一个安装臂内具有接收电路板,接收电路板上设有多个竖向间隔排布的光电接收管;光电发射管与光电接收管一一对应设置,光电接收管用于接收光电发射管发射的信号,以检测平层挡板相对于轿厢的位置变化。本发明增加了光电开关的检测准确性,降低了检测误差。
