Nyob rau hauv-beam photoelectric sensing, tseem hu ua opposed hom, lub transmitter thiab emitter nyob rau hauv nyias vaj tse.Lub teeb tawm ntawm lub transmitter yog tsom ncaj qha rau ntawm lub receiver.Thaum ib yam khoom tawg lub teeb ntawm lub teeb nruab nrab ntawm lub emitter thiab receiver, tus receiver cov zis hloov lub xeev.
Los ntawm-beam sensing yog hom kev paub zoo tshaj plaws uas ua rau qhov kev paub ntev tshaj plaws thiab kev nce siab tshaj plaws.Qhov kev nce qib siab no ua rau cov khoom siv hluav taws xob los ntawm cov kab hluav taws xob tuaj yeem siv tau rau hauv qhov chaw pos huab, plua plav thiab qias neeg.
