Profinet yog Ethernet-raws li kev lag luam kev sib txuas lus raws tu qauv, dav siv nyob rau hauv automation tswj systems, Profinet cable tshwj xeeb yuav tsum tau tshwj xeeb yog tsom rau lub cev yam ntxwv, hluav taws xob kev ua tau zoo, ib puag ncig adaptability thiab installation yuav tsum tau. Kab lus no yuav tsom mus rau Profinet cable rau kev txheeb xyuas ntxaws.
I. Cov yam ntxwv ntawm lub cev
1, cable hom
Shielded Twisted Pair (STP / FTP): Shielded Twisted Pair yog pom zoo kom txo cov electromagnetic cuam tshuam (EMI) thiab crosstalk. Shielded twisted khub tuaj yeem tiv thaiv sab nraud electromagnetic cuam tshuam thiab txhim kho kev ruaj ntseg thiab kev ntseeg siab ntawm cov teeb liab kis tau tus mob.
Unshielded Twisted Pair (UTP): Unshielded Twisted Pair tuaj yeem siv nyob rau hauv ib puag ncig uas tsis tshua muaj hluav taws xob cuam tshuam, tab sis tsis pom zoo siv rau hauv kev lag luam ib puag ncig.
2, cable qauv
Plaub khub ntawm twisted-pair cable: Profinet cable feem ntau muaj plaub khub ntawm twisted-pair cable, txhua khub ntawm cov xov hlau muaj li ntawm ob lub xov hlau rau kev xa cov ntaub ntawv thiab cov khoom siv hluav taws xob (yog tias tsim nyog).
Hlau txoj kab uas hla: Hlau diameters feem ntau yog 22 AWG, 24 AWG, los yog 26 AWG, nyob ntawm seb qhov kis tau tus mob thiab cov teeb liab yuav tsum muaj zog. 24 AWG yog qhov tsim nyog rau kev sib kis ntev dua, thiab 26 AWG yog qhov tsim nyog rau kev ncua deb.
3. Connector
RJ45 connector: Profinet cables siv tus qauv RJ45 connectors los xyuas kom meej compatibility nrog Profinet li.
Locking Mechanism: RJ45 connectors nrog locking mechanism raug pom zoo rau kev lag luam ib puag ncig los tiv thaiv kev sib txuas xoob thiab ua kom muaj kev ntseeg siab ntawm kev sib txuas.
Qhov thib ob, ib puag ncig adaptability
1, Kub ntau yam
Dav kub tsim: Profinet cable yuav tsum tau ua hauj lwm kom zoo nyob rau hauv ib tug dav kub ntau yam, feem ntau yuav tsum tau los txhawb -40 ° C mus rau 70 ° C kub ntau yam.
2 、 Kev tiv thaiv qib
Kev tiv thaiv qib siab: Xaiv cov cables uas muaj kev tiv thaiv siab (xws li IP67) los tiv thaiv kev nkag ntawm cov plua plav thiab dej vapor rau cov chaw ua haujlwm hnyav.
3 、 Kev vibration thiab poob siab tsis kam
Mechanical zog: Profinet cables yuav tsum muaj kev co zoo thiab kev poob siab, haum rau kev co thiab kev poob siab ib puag ncig.
4, tshuaj tiv thaiv
Roj, kua qaub thiab alkali tsis kam: Xaiv cov cables nrog cov tshuaj tiv thaiv xws li roj, kua qaub thiab alkali tsis kam hloov mus rau qhov chaw sib txawv.
III. Yuav tsum tau nruab
1 、 Cov kab hluav taws xob
Tsis txhob muaj kev cuam tshuam hluav taws xob muaj zog: nyob rau hauv cov xaim yuav tsum sim kom tsis txhob muaj kev sib txuam nrog cov kab hluav taws xob muaj zog, lub cev muaj zog thiab lwm yam khoom siv hluav taws xob muaj zog kom txo tau qhov cuam tshuam ntawm electromagnetic.
Tsim nyog layout: Tsim nyog txoj kev npaj ntawm txoj kev xaim, kom tsis txhob muaj kev khoov ntau dhau los yog siab ntawm lub cable, los xyuas kom meej lub cev kev ncaj ncees ntawm lub cable.
2 、 Kho txoj kev
Fixed bracket: Siv lub bracket thiab fixture tsim nyog los xyuas kom meej tias lub cable yog ruaj khov los tiv thaiv kev co los yog txav los ntawm kev sib txuas xoob.
Hlau channel thiab yeeb nkab: Nyob rau hauv ib puag ncig nyuaj, nws raug nquahu kom siv cov xaim channel lossis yeeb nkab rau kev tiv thaiv cable los tiv thaiv kev puas tsuaj thiab ib puag ncig.
IV. Daim ntawv pov thawj thiab cov qauv
1 、 Ua raws li cov qauv
IEC 61158: Profinet cables yuav tsum ua raws li cov qauv ntawm International Electrotechnical Commission (IEC), xws li IEC 61158.
ISO / OSI qauv: Profinet cables yuav tsum ua raws li lub cev txheej thiab cov ntaub ntawv txuas txheej txheej txheem ntawm ISO / OSI qauv.
V. Txoj kev xaiv
1 、 Kev ntsuam xyuas ntawm daim ntawv thov
Kev sib kis nrug: Raws li daim ntawv thov tiag tiag ntawm qhov kis tau tus mob mus rau xaiv hom kab tsim nyog. Kev sib kis luv luv tuaj yeem xaiv 24 AWG cable, kev sib kis ntev yog pom zoo kom xaiv 22 AWG cable.
Ib puag ncig tej yam kev mob: Xaiv qhov tsim nyog cable raws li qhov kub thiab txias, av noo, kev co thiab lwm yam ntawm lub installation ib puag ncig. Piv txwv li, xaiv cov kub kub resistant cable rau qhov kub thiab txias ib puag ncig thiab waterproof cable rau ib puag ncig ntub.
2, xaiv txoj cai cable
Shielded twisted-pair cable: Shielded twisted-pair cable yog pom zoo rau siv nyob rau hauv feem ntau industrial cheeb tsam kom txo tau electromagnetic cuam tshuam thiab crosstalk.
Unshielded twisted-pair cable: tsuas yog nyob rau hauv ib puag ncig ntawm electromagnetic cuam tshuam me me rau siv unshielded twisted-pair cable.
3, xav txog kev hloov pauv ib puag ncig
Qhov kub thiab txias, qib kev tiv thaiv, kev co thiab kev poob siab, kev tiv thaiv tshuaj lom neeg: xaiv cov cables uas tuaj yeem ua haujlwm ruaj khov hauv qhov chaw siv tiag tiag.
