Abstract
본 발명은 자동화 시스템에서 주로 사용하는 위치 및 물체유무 검출용 비접촉식 광센서로서 주신호 처리회로인 PLL IC가 여러개의 입출력 단자를 갖는 광전스위치에 관한 기술이다.The present invention relates to a photoelectric switch having a plurality of input / output terminals of a PLL IC, which is a main signal processing circuit, as a non-contact optical sensor for detecting position and object, which is mainly used in an automation system.
기존 광전 스위치는 1개의 신호 처리부에 1개의 센서부를 갖기 때문에 1개만을 입력정보를 처리할 수 있었으나 본 발명은 여러개의 입력과 출력단자를 운용할 수 있어 여러개의 입력정보를 처리할 수 있는 경제적인 광전스위치로, 특히 수광부 소자에서 받은 소신호의 감도를 조절하여 최종출력의 신호를 보상하는 기능이 있어 물체의 형상에서 반사되는 빛의 세기가 작은 경우에도 우수한 성능을 발휘하는 감도조절기능형 멀티채널 광전스위치이다.Conventional photoelectric switch has one sensor unit, so it can process only one input information. However, the present invention can operate multiple input and output terminals, which is economical to process multiple input information. It is a photoelectric switch, in particular, the function of compensating the signal of the final output by adjusting the sensitivity of the small signal received from the light-receiving element element. It is a photoelectric switch.
