NPN Sib Nqus Hloov

Yooj yim muab tso, PNP NPN Sib Nqus Hloov Hloov xa cov ntaub ntawv hais txog ib qho khoom muaj los yog txav mus rau hauv lub teeb liab hluav taws xob. Thaum ib yam khoom nkag mus rau hauv lawv qhov ntau, lawv tso tawm ntawm - lub xeev teeb liab. Muaj qee qhov sib txawv ntawm qhov sib txawv ntawm cov sensors sib txawv, raws li tau piav qhia hauv qab no:

• Yuav ua li cas Capacitive Proximity Sensors ua haujlwm

Capacitive sib thooj sensors ua haujlwm los ntawm kev kuaj xyuas cov kev hloov pauv ntawm lub peev xwm ntawm lub sensor thiab cov khoom. Yam xws li kev ncua deb thiab cov khoom loj cuam tshuam rau lub peev xwm. Lub sensor tsuas pom qhov kev hloov pauv hloov pauv ntawm ob.

• Yuav ua li cas Inductive Proximity Sensors ua haujlwm

Inductive sensors ntes eddy tam sim no, uas yog generated los ntawm ib tug sab nraud magnetic teb ntawm ib tug conductive nto thiab ua rau sib nqus poob. Ib qho kev kuaj xyuas coil tsim ib qho AC magnetic teb thiab kuaj pom qhov hloov pauv impedance los ntawm cov eddy tam sim no generated.

• Yuav Ua Li Cas Sib Nqus Sib Nqus Hloov Ua Haujlwm

Sib nqus sib sib zog nqus keyboards yog qhov yooj yim thiab ncaj nraim. Lub reed kawg ntawm qhov hloov pauv yog ua los ntawm cov hlau nplaum. Thaum lub reed hloov tau qhib thiab nyob rau hauv lub xeev qhib, lub sensor kuj tig rau.

Qhov tseem ceeb, qhov sib thooj sensors tsis cuam tshuam los ntawm cov xim ntawm qhov chaw lawv pom. Lawv cia siab rau qhov khoom txav thiab txav mus, yog li nws cov xim tsis cuam tshuam rau qhov kev ua haujlwm ntawm lub sensor.

01 - TSIS/NC
TSIS TAU: Feem ntau Qhib; NC: Nquag kaw
02 - NPN/PNP
NPN: Qhia tias lub sensor muaj ib qho ua tau -hauv NPN transistor ua tus tso zis tsav transistor. PNP: Qhia tias lub sensor muaj ib qho ua tau -nyob rau hauv PNP transistor ua tus tso zis tsav transistor.
03 - NPN/NO
Lub sensor muaj qhov ua tau -hauv NPN tso zis transistor. Nyob rau hauv ib txwm muaj xwm txheej, NPN tso zis transistor tsis ua haujlwm, thiab cov xaim dub tso tawm qib siab. Thaum kuaj pom ib yam khoom, NPN tso zis transistor qhib, thiab cov hlau dub tso tawm qis qis. Cov tsav tam sim no tsawg dua 200mA.

04 - NPE NC
Lub sensor muaj qhov ua tau -hauv NPN tso zis transistor. Nquag, nws ib txwm raug kaw. Lub NPN tso zis transistor yog qhib, thiab cov hlau dub tso tawm ib theem qis. Cov tsav tam sim no tsawg dua 200mA. Thaum kuaj pom ib yam khoom, NPN tso zis transistor rov qab mus rau qhov tsis ua haujlwm, thiab cov xaim dub tawm ntawm qib siab.
05 - PNP NO
Lub sensor muaj qhov ua tau -hauv PNP tso zis transistor. Nquag, nws ib txwm qhib. PNP tso zis transistor tsis ua haujlwm, thiab cov xaim dub tso tawm qis qis. Thaum kuaj pom ib yam khoom, PNP tso zis transistor activates, thiab cov hlau dub outputs theem siab. Cov tsav tam sim no tsawg dua 200mA.

06 - PNP NC
Lub sensor muaj qhov ua tau -hauv PNP tso zis transistor. Nquag, nws ib txwm raug kaw. Lub NPN tso zis transistor yog qhib, thiab cov hlau dub tso tawm ib theem siab. Tus tsav tam sim no tsawg dua 200 mA. Thaum kuaj pom ib yam khoom, NPN tso zis transistor rov qab mus rau qhov tsis ua haujlwm, thiab cov hlau dub tso tawm qis qis.

Kuv yuav xaiv qhov zoo me me square PNP NPN Proximity Hloov li cas rau kuv daim ntawv thov? Dab tsi tseem ceeb parameter yuav tsum xav txog?

A1: Thaum xaiv lub sensor, thov tsom mus rau tsib yam nram qab no kom ntseeg tau tias kev ua haujlwm ruaj khov thiab txhim khu kev qha:

Kev Ntsuas Qhov Ncauj: Qhov no yog qhov ntsuas tseem ceeb, xa mus rau qhov kev ncua deb ntawm lub ntsuas hluav taws xob tuaj yeem ntseeg tau cov qauv hlau lub hom phiaj (feem ntau qis -carbon steel). Me me square sensors feem ntau muaj kev tshawb pom luv luv, xws li 1mm, 2mm, lossis 4mm. Hauv kev siv cov tswv yim, cov coefficient attenuation yuav tsum raug txiav txim siab: rau cov hlau tsis yog - ferrous (xws li tooj liab thiab txhuas), qhov kev kuaj pom tau zoo yuav raug txo qis (feem ntau 30% -60% ntawm tus nqi nominal).

Dimensions thiab Installation Method: Square sensors feem ntau muaj nyob rau hauv embedded (shielded) thiab non-embedded (unshielded) hom.

Hom Embedded: Lub sensor lub hlau casing npog rau sab ntawm lub qhov muag pom, tso cai rau kev tshawb pom pem hauv ntej. Nws tuaj yeem ntsia tau yaug nrog cov hlau nyob ib puag ncig yam tsis muaj qhov cuam tshuam tsis tseeb thiab muaj zog tiv thaiv kev cuam tshuam rau sab nraud, tab sis qhov kev tshawb pom deb kuj luv.

Tsis yog - hom embedded: Tsis muaj hlau thaiv nyob ib puag ncig ntawm qhov chaw pom, ua rau pom qhov ntev dua. Txawm li cas los xij, cov hlau txaus- qhov chaw dawb yuav tsum nyob ib ncig ntawm lub sensor thaum lub sijhawm teeb tsa; txwv tsis pub, kev dag ntxias lossis kev ua haujlwm tsis zoo yuav tshwm sim.

Hom tso zis: Xaiv raws li koj qhov kev tswj hwm.

NPN hom (tam sim no inflow): Thaum cov zis tawm tsawg, tam sim no ntws los ntawm lub load mus rau lub sensor tso zis. Feem ntau pom nyob rau hauv Asian thiab European PLCs.

PNP hom (tam sim no outflow): Thaum cov zis siab, tam sim no ntws los ntawm sensor tso zis mus rau lub load. Feem ntau pom nyob rau hauv European PLCs.

Nquag qhib (NO) / Nquag kaw (NC): Xaiv raws li kev xav tau.

Fais fab mov voltage: Feem ntau DC voltage ntau ntawm 10-30V; xyuas kom compatibility nrog koj lub hwj chim mov.

Lub hom phiaj cov khoom thiab qhov loj me: Cov khoom yuav raug kuaj xyuas yuav tsum yog xim hlau. Ferromagnetic hlau (xws li hlau thiab hlau) qhia pom qhov zoo tshaj plaws. Lub hom phiaj qhov loj me yuav tsum tsis txhob me dua li qhov ntsuas qhov ntsuas qhov loj me kom ntseeg tau tias ruaj khov.

Kev Pom Zoo: Nws yog qhov zoo tshaj plaws los ua qhov kev kuaj mob tiag tiag ua ntej ua tiav qhov tsim.
