      光電開關是傳感器的一種,它把發射端和接收端之間光的強弱變化轉化為電流的變化以達到探測的目的。由于光電開關輸出回路和輸入回路是電隔離的(即電絕緣),所以它可以在許多場合得到應用。采用集成電路技術和SMT表面安裝工藝而制造的新一代光電開關器件,具有延時、展寬、外同步、抗相互干擾、可靠性高、工作區域穩定和自診斷等智能化功能。這種新穎的光電開關是一種采用脈沖調制的主動式光電探測系統型電子開關,它所使用的冷光源有紅外光、紅色光、綠色光和藍色光等,可非接觸,無損傷地迅速和控制各種固體、液體、透明體、黑體、柔軟體和煙霧等物質的狀態和動作。具有體積小、功能多、壽命長、精度高、響應速度快、檢測距離遠以及抗光、電、磁干擾能力強的優點。

      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

      www.turangxiufuu.cnwww.yanglaoyuand.cnexternal synchronization, anti-interference, high reliability, stable working area and self-diagnosis. 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.
