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(即电绝缘),所以它可以在许多场合得到应用。采用集成电路技术和SMT表面安装工艺而制造的新一代光电开关器件,具有延时、展宽、外同步、抗相互干扰、可靠性高、工作区域稳定和自诊断等智能化功能。这种新颖的光电开关是一种采用脉冲调制的主动式光电探测系统型电子开关,它所使用的冷光源有红外光、红色光、绿色光和蓝色光等,可非接触,无损伤地迅速和控制各种固体、液体、透明体、黑体、柔软体和烟雾等物质的状态和动作。具有体积小、功能多、寿命长、精度高、响应速度快、检测距离远以及抗光、电、磁干扰能力强的优点。

Photoelectric switch is a kind of sensor, which converts the change of light intensity between transmitter and receiver into the change of current to achieve the purpose of detection. Because the output circuit and input circuit of photoelectric switch are electrically isolated, it can be used in many occasions. A new generation of optoelectronic switching devices manufactured by integrated circuit technology and SMT surface mounting technology have intelligent functions such as delay, broadening, www.yanglaoyuant.com.cnwww.diandongment.com.cnwww.taiyuanbanjia.com.cnwww.gonglujiemuju.cn

This novel photoelectric switch is an active photoelectric detection system electronic switch with pulse modulation. The cold light source used in the switch is infrared light, red light, green light and blue light. It can quickly control the state and action of various solid, liquid, transparent body, black body, soft body and smoke without any damage. It has the advantages of small size, multi-function, long life, high precision, fast response, long detection distance and strong anti-light, electric and magnetic interference ability.
