Reed Switch uye Hall Effect Sensors

Reed Switch uye Hall Effect Sensors
Magnetic sensors anoshandiswa mune zvese kubva kumotokari kusvika kunharembozha. Ndeapi magineti andinofanira kushandisa neangu magineti sensor? Ndinofanira kushandisa Hall effect sensor kana chinja rutsanga? Iyo magineti inofanirwa kutungamirwa sei kune sensor? Ndedzipi kushivirira kwandinofanira kuva nehanya nazvo? Dzidza zvakawanda neK&J kufamba-kuburikidza nekutsanangura magineti-sensor musanganiswa.

Chii chinonzi Reed Switch?

Maviri Hall effect sensors uye rutsanga switch. Kuchinja kwetsanga kuri kurudyi.
Shanduko yetsanga ishanduko yemagetsi inoshandiswa neyakaiswa magineti. Inoumbwa nepeya yezvinobatika patsanga dzesimbi dzine ferrous muhamvuropu yegirazi isina mhepo. Macontacts anowanzo kuvhurika, asingaite magetsi. Iyo switch inobatidzwa (yakavharwa) nekuunza magineti pedyo ne switch. Kana magineti yabviswa, switch yetsanga inodzokera kunzvimbo yayo yekutanga.

Chii chinonzi Hall Effect Sensor?
A Hall effect sensor is transducer iyo inosiyana yainobuda voltage mukupindura shanduko mune magineti. Mune dzimwe nzira, Hall effect sensors inogona kupedzisira yaita basa rakafanana sechinja rutsanga, asi isina zvikamu zvinofamba. Funga nezvayo sechinhu chakasimba-chenyika, chakanakira madhijitari maapplication.

Ndeipi yeaya ma sensor maviri akakodzera kune yako application zvinoenderana nehuwandu hwezvinhu. Zvinhu zvinosanganisira mutengo, kutaridzika kwegineti, frequency renji (tsanga inochinja kazhinji haishandiswe kupfuura gumi kHz), chiratidzo chebhaunzi uye dhizaini yeakabatana logic wedunhu.

Magnet - Sensor Orientation
Musiyano wakakosha pakati petsanga switch uye Hall effect sensors ndiko kutaridzika kwakakodzera kunodiwa kune activate magineti. Hall effect sensors inoshanda kana magineti ari perpendicular kune yakasimba-state sensor ikaiswa. Vazhinji vanotarisa magineti yekumaodzanyemba pole kuti yakatarisana nenzvimbo yakaratidzwa pane sensor, asi tarisa iyo yakatarwa pepa re sensor yako. Kana iwe ukatenderedza magineti kumashure kana padivi, sensor haishande.

Reed switches mudziyo wemuchina une zvikamu zvinofamba. Inoumbwa newaya mbiri dzeferromagnetic dzakaparadzaniswa nekamukana kadiki. Pamberi pesimba remagineti rinoenderana netambo idzodzo, dzinobatana, dzichiita magetsi. Mune mamwe mazwi, iyo magineti axis yemagineti inofanirwa kuenderana neiyo axis yakareba yetsanga switch. Hamlin, mugadziri wetsanga switch, ane yakanakisa application note pachinhu ichi. Inosanganisira madhayagiramu makuru anoratidza nzvimbo uye maitiro ayo sensor ichashanda.
Yakakodzera Magnet Oriental: Iyo Hall effect sensor (kuruboshwe) vs. reed switch (kurudyi)
Izvo zvinofanirwa kucherechedzwa kuti mamwe magadzirirwo anogoneka uye anowanzoshandiswa. Semuenzaniso, Hall effect sensors inogona kuona simbi ye "fan" inotenderera. Mashizha esimbi efeni anopfuura pakati pemagineti yakamira uye sensorary sensor. Kana simbi iri pakati pezviviri, iyo magineti inodzoserwa kure kubva kune sensor (yakavharwa) uye switch inovhura. Kana simbi inofamba, magineti inovhara switch
