Reed Sensors vs. Hall Effect Sensors

Reed Sensors vs. Hall Effect Sensors

Hall Effect sensors kuj siv lub xub ntiag ntawm lub zog sib nqus los ua lub zog qhib thiab kaw ntawm qhov hloov pauv, tab sis qhov ntawd yog qhov uas lawv qhov zoo sib xws xaus. Cov sensors no yog cov khoom siv hluav taws xob semiconductor uas tsim cov hluav taws xob los qhib cov khoom siv hluav taws xob hauv lub xeev tsis yog cov keyboards nrog cov khoom txav. Qee qhov sib txawv tseem ceeb ntawm ob hom kev hloov pauv muaj xws li:

Durability. Hall Effect sensors yuav xav tau ntim ntxiv los tiv thaiv lawv ntawm ib puag ncig, thaum cov reed sensors raug tiv thaiv hauv cov thawv ntim hermetically. Txawm li cas los xij, txij li cov reed sensors siv txhua yam txav, lawv muaj kev cuam tshuam ntau dua rau hnav thiab tsim kua muag.
Kev thov hluav taws xob. Hall Effect keyboards yuav tsum muaj qhov ntws tsis tu ncua. Reed sensors, ntawm qhov tod tes, tsuas yog xav tau lub zog los tsim kom muaj qhov sib nqus sib nqus.
Vulnerability rau kev cuam tshuam. Reed keyboards tuaj yeem ua rau muaj kev poob siab hauv qee qhov chaw, thaum Hall Effect keyboards tsis yog. Hall Effect keyboards, ntawm qhov tod tes, muaj kev cuam tshuam rau electromagnetic cuam tshuam (EMI).
Ntau zaus. Hall effect sensors yog siv tau nyob rau hauv ntau qhov ntau zaus, thaum reed sensors feem ntau txwv rau cov ntawv thov nrog zaus qis dua 10 kHz.
Nqi. Ob hom sensor yog tus nqi tsim nyog, tab sis tag nrho cov reed sensors yog pheej yig dua los tsim, uas ua rau Hall Effect sensors kim kim dua.
Cov cua kub. Reed sensors ua tau zoo dua hauv qhov kub kub lossis txias txias, thaum Hall Effect sensors nyiam ntsib teeb meem kev ua haujlwm ntawm qhov kub thiab txias.
