Lub tshuab hluav taws xob sib nqus yog ntau yam khoom siv hluav taws xob uas ua haujlwm los ntawm kev teb rau cov chaw sib nqus. Los ntawm Hall Effect mus rau reed keyboards, tshawb xyuas lawv cov haujlwm, hom, thiab ntau yam kev siv.

Dab tsi yog Magnetic Switch?

Ib tug magnetic hloov yog ib qho khoom siv hluav taws xob uas ua haujlwm los ntawm kev teb rau qhov muaj qhov sib nqus. Nws ua haujlwm los ntawm kev kaw lossis qhib nws cov neeg sib cuag raws li lub zog ntawm cov hlau nplaum. Tshwj xeeb, qhov hloov pauv tseem raug kaw (on) thaum raug cov hlau nplaum muaj zog thiab qhib (tawm) thaum lub teb raug tshem tawm.

Lub Magnetic Switch ua haujlwm li cas?

Lub magnetic hloov ua haujlwm los ntawm kev sib cuam tshuam ntawm ob lub ntsiab lus tseem ceeb: lub tshuab hluav taws xob sib nqus thiab lub reed hloov. Lub tshuab hluav taws xob sib nqus yog cov hlau nplaum me me uas muaj nyob rau hauv qhov chaw tiv thaiv, thaum lub reed hloov muaj ib lub iav raj uas muaj ob qho kev sib cuag hlau. Thaum lub tshuab hluav taws xob sib nqus los ze rau ntawm lub reed hloov, nws qhov chaw sib nqus cuam tshuam cov hlau sib txuas, ua rau lawv txuas thiab kaw lub voj voog lossis cais thiab qhib nws.

Lub hauv paus ntsiab lus muaj xws li excitation thiab de-energization ntawm electromagnetic kauj. Thaum hluav taws xob ntws los ntawm lub kauj, nws tsim ib qho chaw sib nqus uas nyiam cov hlau nplaum nyob ze lossis cov hlau nplaum. Thaum tam sim no nres, lub magnetic teb vau, tso lub zog cia. Cov txheej txheem no zoo ib yam li ncab thiab tso cov roj hmab band, qhov twg lub zog tawm sai sai.

Cov keyboards sib nqus muaj ntau yam thiab tiv taus ib puag ncig xws li dej, roj, dej khov, plua plav, thiab lwm yam. Cov piv txwv xws li electromechanical keyboards, Hall sensors, thiab reed keyboards. Lawv durability thiab yooj ua rau lawv haum rau ntau yam kev siv nyob rau hauv ob qho tib si kev lag luam thiab hauv tsev.

Hom Sib Nqus Hloov

Sib nqus keyboards tuaj nyob rau hauv ntau hom, txhua tus tsim los rau cov kev siv tshwj xeeb thiab cov qauv kev khiav hauj lwm. Hauv qab no yog cov hom tseem ceeb ntawm magnetic keyboards:

Hall Effect Switches

Hall Effect keyboards yog cov khoom siv hluav taws xob semiconductor uas ua haujlwm yam tsis muaj kev sib cuag nrog cov neeg kho tshuab, ua rau lawv ruaj khov thiab tiv taus cov neeg kho tshuab hnav lossis poob siab. Cov keyboards no feem ntau siv los txwv kev hloov pauv hauv cov ntawv thov xws li lub tshuab of elevator, cov cuab yeej siv hluav taws xob hauv Hoobkas, thiab tsheb.

Hall Effect keyboards muab kev hloov pauv yooj yim hauv kev tsim nrog cov kev xaiv xws li Unipolar (kuaj ib tus ncej sib nqus) lossis Omnipolar (kuaj ob sab qaum teb thiab sab qab teb) kev teeb tsa. Lawv qhov sib nqus rhiab heev nyob ntawm qhov siv hluav taws xob tam sim no thiab hom magnetic teb generated, tso cai rau lawv kom haum rau ntau yam kev thov.

Reed Hloov

Reed keyboards yog rhiab heev rau magnetic teb thiab paub txog lawv cov nqi-zoo thiab yoog raws. Cov keyboards no tau siv dav hauv qhov sib thooj lossis txwv kev hloov pauv, suav nrog xov tooj ntawm tes, lub qhov rooj hauv tsev, ceeb toom kev ruaj ntseg, tshuab hnyav, thiab lub qhov rooj tsheb.

Reed keyboards tuaj yeem hloov kho raws li yam xws li reed loj, ib puag ncig, thiab lub zog ntawm kev siv magnetic teb. Lawv qhov kev ua tau zoo yog ntsuas raws li lub zog magneto motive force (AT - Ampere-Turns), ua rau lawv muaj ntau yam rau kev ua haujlwm sib txawv.

Triac los yog Transistor Hloov

Triac thiab Transistor keyboards yog qhov nyuaj dua vim lawv cov circuitry ntxiv. Lawv feem ntau yog siv rau kev tswj fais fab thiab hloov daim ntawv thov hauv AC (Triac) lossis DC (Transistor) voltage systems. Cov keyboards no muaj zog thiab tsim nyog rau cov ntawv thov tam sim no lossis hnyav, xws li tswj cov motors, relays, lossis inductive loads.

Lawv lub peev xwm nqa tam sim no tuaj yeem txhim kho los ntawm kev sib txuas nrog Hall Effect lossis Reed keyboards, ua rau lawv zoo tagnrho rau kev xav tau kev lag luam ib puag ncig qhov kev ntseeg siab thiab lub zog tseem ceeb.

Qhov twg siv magnetic switches?

Sib nqus keyboardsyog dav siv nyob rau hauv ntau yam lag luam thiab kev siv vim lawv versatility, kev cia siab, thiab muaj peev xwm ua hauj lwm yam tsis muaj kev sib cuag lub cev. Hauv qab no yog qee qhov chaw tseem ceeb uas siv cov hlau nplaum sib nqus:

• Automotive Applications: Siv nyob rau hauv nres lub teeb hloov, lub qhov rooj sensors, iav txoj hauj lwm nrhiav kom tau, throttle txoj hauj lwm sensing, thiab lub log ceev xyuas.
• Industrial Automation: Ua hauj lwm rau kev tswj txoj siv conveyor, qhov rooj thiab rooj vag qhov xwm txheej sensing, khoom siv xyuas, ntau lawm kab automation, thiab valve txoj hauj lwm nrhiav kom tau.
