Thaum lub ntsuas hluav taws xob hloov tsis yooj yim mus rau qhov khoom nrhiav kom tau los yog thaum nws yooj yim raug puas ntsoog thaum nws nyob ze rau qhov chaw kuaj pom, thaum qhov chaw muaj tsawg, lossis thaum pom qhov khoom me me (siv fiber ntau rau kev kuaj pom) photoelectric mus yuav siv tau. Nws tsis txawv ntawm cov hlau thiab tsis yog hlau. Nws yuav tsum raug sau tseg tias seb tus tes hloov qhov raug txiav txim siab raws li seb tus yees duab pob hluav taws xob tau txais lub teeb ci lossis tsis. Nws tau muab faib ua hom teeb ci ntsa iab thiab tsaus xim. Raws li daim ntawv ntawm cov hluav taws xob tsim tawm, nws tseem muab faib ua PNP hom thiab NPN hom; Thaum lub ntsuas hluav taws xob hloov pauv tau yooj yim mus rau qhov khoom hauv qhov ntsuas thiab tsis yooj yim rau puas, qhov inductive hom yog siv los kuaj cov khoom hlau, thiab hom muaj peev xwm siv los kuaj cov khoom tsis yog hlau. Raws li daim ntawv ntawm cov hluav taws xob tsim tawm, nws tseem muab faib ua PNP hom thiab NPN hom; qee cov ntsuas kab hluav taws xob kuj tseem tau pob qhov rooj los kho qhov mob siab. Hais txog kev hloov khoom siv yees duab, neeg yuav muaj lus nug txog qhov no, tam sim no kuv yuav teb lawv. Lub npe hu ua photoelectric yog lub ntsiab lus ntawm photoelectric sensor, uas yog qhov luv ntawm photoelectric qhov sib hloov hloov pauv, uas tau pom los ntawm thaiv los yog cuam tshuam lub teeb pom kev los ntawm lub nruas pom, yog li nws tuaj yeem paub qhov kuaj pom lossis tsis muaj khoom. Lub yees duab hluav taws xob hloov yog qhov zoo ntawm lub sensor, thiab nws lub luag haujlwm yog kuaj tau. Txawm li cas los xij, txij thaum cov tso zis hluav taws xob hloov ntawm photoelectric hloov tawm yog hluav taws xob cais, nws tuaj yeem siv rau ntau lub sijhawm. Cov haujlwm ntawm cov twj hluav taws xob photoelectric tau ncua, nthuav dav, ua tiav sab nraud, tiv thaiv kev cuam tshuam, ntseeg siab, thiab thaj chaw ua haujlwm ruaj khov.
Cov ntsiab lus saum toj no yog peb qhov kev qhia luv luv rau koj. Yog tias koj xav paub ntau ntxiv txog qhov kev paub no, lossis kom paub tus qauv ntawm qhov sib thooj sensor, koj zoo siab tos txais hu rau peb thiab peb yuav pabcuam koj lub siab dawb paug.
