Photoelectric mus (photoelectric sensor) yog cov cim luv ntawm photoelectric daws hloov mus. Nws siv cov ntaub thaiv lossis hloov kho ntawm lub teeb ci los ntawm cov khoom pom, thiab lub Circuit Court txuas nrog los ntawm lub voj sib dhos, thiab lub xub ntiag lossis tsis tuaj ntawm lub nruas pom. Nws yog dav siv nyob rau hauv kev lag luam thiab kev ua liaj ua teb. Nws cov tshuab ua haujlwm yog tias photoelectric hloov hloov lub teeb meem tam sim no mus rau lub teeb liab ntawm lub transmitter thiab nws tawm, thiab cov txais tau tshawb pom lub hom phiaj raws li qhov sib zog lossis qhov muaj lub teeb pom. Muaj DC thiab AC photoelectric keyboards. Muab faib ua ob kab, peb kab, plaub kab thiab lwm yam.
\
Lub tshuab hluav taws xob ob-xaim hluav taws xob txuas nrog rau hauv cov kab nrog cov load hauv Circuit Court.
Qhov peb-xaim photoelectric hloov tau muab faib ua NPN hom thiab PNP hom. Cov xov tooj xim av tau txuas nrog tus ncej zoo ntawm lub zog hluav taws xob, cov xov hlau xiav txuas nrog rau qhov tsis zoo ntawm cov hluav taws xob, thiab cov hlau dub yog cov teeb liab xaim. Rau NPN photoelectric hloov, qhov tso tawm tsis zoo yog txuas nrog lub ntsaws, thiab lwm qhov kawg ntawm lub nra mus txuas rau lub ncej zoo ntawm cov khoom siv fais fab. PNP hom photoelectric hloov tawm, cov zis hluav taws xob zoo txuas nrog lub thauj khoom, lwm qhov kawg ntawm lub nra sib txuas nrog cov ncej tsis zoo ntawm lub fais fab.
Lub tshuab hluav taws xob plaub xaim hluav taws xob tau muab faib ua NPN ib txwm qhib hom kev nquag kaw thiab PNP ib txwm qhib hom ib txwm kaw, rau qhov xav tau tiag tiag xaiv thiab siv.
Cov khoom thauj khoom tuaj yeem yog tus xov tooj sib tiv tauj, tus xa xov txuas, lossis PLC. Thaum PLC siv los ua kev thauj khoom, yuav tsum tau them nyiaj tshwj xeeb rau qhov sib txuam ntawm qhov zoo thiab qhov tsis zoo ntawm cov teeb liab hluav taws xob, thiab qhov tsim nyog photoelectric NPN thiab PNP photoelectric keyboards yuav tsum xaiv kom raug.
