Ib, Core sib txawv: sib txawv los ntawm kev tsim logic rau daim ntawv thov scenarios
1. Lub cev qauv thiab qib kev tiv thaiv
RJ45 txais cov qauv duab plaub nrog qhov ntev ntawm kwv yees li 21.5mm × 11.7mm × 15mm, tso siab rau cov yas buckles rau fixation. Kev tiv thaiv qib feem ntau yog IP20, ua rau nws nyuaj rau tiv thaiv plua plav, dej, thiab roj yaig. Txawm hais tias nws cov hlau sib txuas tau raug txhim kho rau oxidation tsis kam los ntawm kub plating, lawv tseem ua rau tsis ua hauj lwm hauv qhov chaw ntub dej lossis corrosive. Piv txwv li, lub Hoobkas 3C tau ntsib 2-teev kaw ntawm nws cov SMT cov kab ntau lawm vim dej nkag mus rau hauv RJ45 interface, nthuav tawm nws qhov tsis zoo hauv kev hloov pauv ib puag ncig.
M12 connector nta ib tug cylindrical tsim nrog ib txoj kab uas hla ntawm 12 hli raws li nws cov tub ntxhais, thiab ua tiav lub cev stability los ntawm ib tug hlau xov xauv mechanism. Nws qib kev tiv thaiv feem ntau ncav cuag IP67 / IP69K, thiab nws tuaj yeem tiv taus siab - dej ntws tawm thiab qhov kub thiab txias sib txawv. Piv txwv li, LM12 cable Cheebtsam ntawm Lingke Hluav Taws Xob siv cov tshuab moulding kev sib xyaw ua ke thiab tau dhau cov ntawv pov thawj tshuaj tsuag ntsev, ua kom pom kev ua tau zoo hauv cov xwm txheej xws li photovoltaic fais fab nroj tsuag thiab tshuaj nroj tsuag. Nws hexagonal arc-zoo li tus xauv lub nplhaib sab nrauv tsim disperses lub zog ua haujlwm, tsis txhob ntog hauv qhov chaw nqaim, thiab txhim kho kev txhim kho ntxiv.
2. Kev sib kis tau zoo thiab tiv thaiv - muaj peev xwm cuam tshuam
RJ45 txhawb kev sib kis tus nqi los ntawm 10Mbps mus rau 10Gbps, tab sis ntev -qhov deb siab- zaus cov teeb liab yuav raug cuam tshuam. Nyob rau hauv kev cob qhia nrog ntom zaus converters thiab motors, qhov me ntsis yuam kev feem ntau tshaj 10 ⁻⁶, ua rau nws nyuaj rau ua tau raws li xoom latency yuav tsum tau ntawm industrial cov khoom. Tsis tas li ntawd, RJ45 muaj kev ua haujlwm tsis zoo ntawm EMC, txwv tsis pub sib tshooj ntawm nws cov hlau casing thiab lub qhov (socket), siab impedance ntawm cov zaus siab, thiab tsis tuaj yeem tsim kev tiv thaiv zoo, ua rau nws tsis muaj zog rau lub cev hluav taws xob emission.
M12 connector phim cov kev xav tau ntawm kev sib kis los ntawm kev sib txawv encoding (D encoding, X encoding): D encoding txhawb 100Mbps Ethernet, thaum X encoding yog tsim los rau Gigabit thiab saum toj no, txhawb 10Gbps kis tau tus mob (Cat.6A cable, 100 meters deb), thiab muaj zog tiv thaiv - cuam tshuam muaj peev xwm. Piv txwv li, Zhengcheng Electric X-code M12 connector tau dhau PNO cov neeg siv cov ntawv pov thawj hauv lub koom haum thiab tuaj yeem cuam tshuam crosstalk mus rau hauv qab -65dB hauv bandwidth ntawm 500MHz, ua tau raws li kev cai raws sijhawm xws li Profinet IRT thiab EtherCAT. Nws 360℃tag nrho cov ntaub thaiv npog tsim ua ib lub tawb Faraday los ntawm kev sib koom ua ke ntawm cov hlau casing thiab ntsaws, ua rau kom muaj kev tawm tsam ntawm hluav taws xob hluav taws xob hluav taws xob.
3. Mechanical lifespan thiab kev ntseeg tau
Lub plug thiab unplug lub neej ntawm RJ45 feem ntau yog 500{2}}2500 zaug, thiab cov khoom siv high-end tuaj yeem ncav cuag 5000 zaug, tab sis nws yog qhov yooj yim rau loosening hauv vibration scenarios. Piv txwv li, nyob rau hauv cov xwm txheej uas tus neeg hlau caj npab ua haujlwm ntawm lub siab zaus (10-500Hz kev vibration), RJ45 interface yog nquag teeb liab cuam tshuam vim buckle tsis ua haujlwm.
Lub plugging thiab unplugging lub neej ntawm M12 connectors feem ntau ncav cuag 1000-5000 lub sij hawm, thiab ib tug zoo leap nyob rau hauv anti kev co kev ua tau zoo yog tiav los ntawm cov xov locking mechanism. Cov ntaub ntawv xeem tiag tiag qhia tau tias qhov kev vibration tsis kam ntawm M12 yog 5 npaug ntawm RJ45, thiab tus nqi tsis ua haujlwm tsuas yog 1/5 ntawm tom kawg. Piv txwv li, nyob rau hauv lub teeb liab tswj system ntawm rail transit, lub M12 connector yuav xyuas kom meej millisecond theem teb ntawm lub tsheb ciav hlau qhov chaw, txawm tswj lub teeb liab stability ntawm ib tug ceev ntawm 380km / h.
2, Alternative feasibility: scenario driven technology xaiv
1. Muaj automation thiab ntse tsim
Hauv kev lag luam lub koob yees duab tsis pom kev, PLC tswj, thiab lwm yam xwm txheej, M12 connectors tau dhau los ua qhov kev xaiv. Nws txhawb xoom latency kis tau tus mob ntawm 120 ntas ib ob ntawm cov duab thiab yog 60% me me nyob rau hauv loj dua RJ45, ua rau nws tshwj xeeb tshaj yog haum rau qhov chaw constrained scenarios xws li neeg hlau pob qij txha thiab tsheb systems. Piv txwv li, nyob rau hauv AGV neeg hlau, lub M12 connector muaj peev xwm ib txhij xa cov navigation signals (24V tswj signals) thiab tsav tsheb fais fab (16A / 63V DC), txo wiring complexity los ntawm 60%.
RJ45 tsuas yog tsim rau sab hauv tsev tsis tshua muaj kev cuam tshuam ib puag ncig, xws li chaw ua haujlwm LANs lossis cov khoom siv hluav taws xob sib sib zog nqus, vim nws qib kev tiv thaiv qis thiab kev co tsis zoo.
2. Lub zog tshiab thiab lub zog hluav taws xob
Hauv qhov chaw nres tsheb them nyiaj, M12 connector tuaj yeem ua tiav -lub sijhawm sib txuas lus ntawm rab phom them thiab BMS tswj chav. Nws qhov kub thiab txias tsis kam (-40℃rau +85 degree), corrosion kuj, thiab muaj peev xwm tiv nrog ob qhov kev sib tw ntawm sab nraum zoov kub sib txawv thiab av noo. Piv txwv li, photovoltaic inverters yuav tsum ua haujlwm ruaj khov nyob rau hauv qhov sib txawv ntawm qhov kub ntawm -40℃rau +85 degree, thiab M12 connectors tau dhau UL94 V-0 nplaim retardant ntawv pov thawj los xyuas kom meej kev nyab xeeb nyob rau hauv huab huab cua.
Txawm hais tias RJ45 tuaj yeem txhim kho nws qib kev tiv thaiv los ntawm kev hloov kho qib kev lag luam xws li ntxiv cov hlua khi thiab siv cov hlua tiv thaiv, tus nqi nce ntxiv thiab nws tseem tsis tuaj yeem phim cov neeg kho tshuab kev ntseeg siab ntawm M12.
3. Rail transit thiab onboard systems
Hauv lub tsheb Ethernet, M12 txuas txhawb nqa ADAS cov ntaub ntawv xa mus thiab nws cov kev poob siab tuaj yeem tiv taus 15g kev co vibration, ua tau raws li ISO 7637-2 tus qauv. Piv txwv li, nyob rau hauv lub high-speed rail teeb liab tswj system, lub M12 connector yog tsim los nrog dual redundant xauv (xov + hexagonal locking nplhaib + roj hmab foob), uas txhim kho kev twb kev txuas stability los ntawm 90% nyob rau hauv kev co ib puag ncig.
Vim muaj qhov tsis xws luag ntawm lub snap ntawm kev xauv cov qauv, RJ45 yog qhov nyuaj kom ua tau raws li cov kev cai nruj ntawm cov xwm txheej hauv tsheb.
3, Tus nqi thiab Ecology: Qhov chaw nkaum ntawm kev hloov pauv
Txawm hais tias M12 outperforms RJ45 nyob rau hauv cov nqe lus ntawm kev ua tau zoo, nws cov nqi tseem yog 3-5 npaug ntawm tom kawg. Tsis tas li ntawd, nrog rau ntau xyoo ntawm kev muaj koob meej, RJ45 tau tsim lub ecosystem loj, nrog rau cov Ethernet cables pheej yig, cov cuab yeej siv tau zoo, thiab cov kev daws teeb meem loj. Hauv kev lag luam tsis hnyav, tus nqi zoo ntawm RJ45 tseem txaus nyiam.
Txawm li cas los xij, nrog kev sib sib zog nqus ntawm Kev Lag Luam 4.0, qhov kev thov rau kev ruaj ntseg hauv kev sib txuas ntawm cov cuab yeej tau dhau los ua qhov tseem ceeb. M12 connector yog maj mam txo qis qhov pib rau kev hloov pauv los ntawm kev tsim qauv (xws li kev sib xyaw ua ke ntawm 2-12 cores hauv Lingke LM12), tus qauv kev sib txuas (IEC 61076-2-101), thiab kev txawj ntse txawj ntse (kev ntsuas kub sib xyaw). Piv txwv li, nyob rau hauv high-end manufacturing teb, M12 connectors tau tawg los ntawm spatial txwv ntawm 7-axis linkage scenarios thiab ua ib tug qauv configuration rau industrial robotic caj npab.
