1, Sib piv cov qauv encoding nrog tus nqi sib kis
M12 connectors sib txawv lawv cov dej num los ntawm lub cev encoding, thiab nyob rau hauv siab -ceev Ethernet scenarios, qhov tseem ceeb yuav tsum tau muab rau xaiv encoding hom uas txhawb siab bandwidth:
D encoding: Haum rau 100Mbps Ethernet (100BASE-TX), tsim los nrog 4-core twisted khub cables, nrog rau qhov siab tshaj plaws ntawm 100Mbps. Nws feem ntau yog siv hauv kev faib I / O modules, AGV navigation systems, thiab lwm yam xwm txheej.
X code: tshwj xeeb tshaj yog tsim los rau gigabit thiab saum toj no networks, nws siv 8-core twisted khub (4 khub), txhawb 10Gbps kis tus nqi (10GBASE-T), thiab ua tau raws li siab -cov ntaub ntawv ceev sib cuam tshuam cov kev cai xws li tshuab pom kev thiab 5G + kev lag luam Internet rooj vag. Piv txwv li, X-code M12 connector launched los ntawm Zhengcheng Electric tau dhau PNO cov neeg siv lub koom haum ntawv pov thawj thiab muaj peev xwm ua tau 500MHz bandwidth kis tau tus mob ntawm Cat.6A cables.
Kev xaiv ntawm encoding yuav tsum nruj me ntsis sib phim lub network topology: yog D encoding yuam kev rau gigabit tes hauj lwm, teeb liab attenuation yuav tshwm sim vim tsis txaus kab; Ntawm qhov tsis sib xws, txawm hais tias siv X encoding nyob rau hauv 100Mbps scenarios yog technically ua tau, nws yuav ua rau kom cov nqi thiab thaiv cov complexity.
2, Cable qauv thiab impedance tswj
Kev kub ceev Ethernet muaj hluav taws xob ua tau zoo heev rau cov cables, thiab M12 adapters yuav tsum ua kom tau raws li cov hauv qab no:
Differential impedance: X-code connector yuav tsum tau sib phim nrog 100 Ω sib txawv impedance uas yog raws li tus yam ntxwv ntawm Cat.6A cables kom txo cov teeb liab kev xav. Piv txwv li, DeSoto X-coded M12 connector tswj impedance sib txawv nyob rau hauv ± 5% los ntawm optimizing contact spacing thiab cable twist.
Pair tshuav nyiaj li cas: Plaub khub ntawm twisted khub cables yuav tsum tuav ib tug symmetrical qauv kom tsis txhob coupling ntawm nyob ib sab khub. Lub Lingke LM12 cable sib dhos tau txais kev ywj pheej tiv thaiv tsim los tiv thaiv cov khub sib txuas sib txuas mus rau hauv qab -65dB, ua tau raws li EMC cov cai rau 10Gbps kis tau tus mob.
Hlau txoj kab uas hla thiab attenuation: High speed signals yuav tsum tau ib txoj kab uas hla ntawm 24AWG los yog saum toj no kom txo tau siab - zaus attenuation. Piv txwv li, ntawm 100 meter Cat.6A cable, 10GHz teeb liab attenuation yuav tsum tau tswj tsis pub dhau 24dB, uas tso siab rau kev xav tau ntawm cov txheej tiv thaiv (feem ntau yog 30 μ hauv kub) thiab crimping txheej txheem ntawm M12 connectors.
3, Shielding Design thiab Electromagnetic Compatibility
Muaj zog electromagnetic cuam tshuam (EMI) nyob rau hauv kev lag luam ib puag ncig, thiab kev tiv thaiv tsim ntawm M12 adapters yuav tsum tau ua raws li cov hauv qab no:
360℃tag nrho kev tiv thaiv: X-code connector yuav tsum muaj lub plhaub hlau thiab braided shielding txheej los tsim cov kab noj hniav txuas ntxiv. Piv txwv li, Zhengcheng Electric X- hom connector siv cov cuab yeej molding kev sib xyaw kom tshem tawm cov qhov khoob khoob thiab txo cov hluav taws xob xau kom qis dua -80dB.
Kev tiv thaiv txheej hauv av: Cov txheej thaiv kab thaiv yuav tsum muaj kev ntseeg siab los ntawm M12 plhaub, thiab cov av tiv thaiv yuav tsum tsawg dua 0.1 Ω. Desao siv kub-plated grounding contacts kom ntseeg tau tias tsis tshua muaj kev sib cuag txawm nyob rau hauv ib puag ncig kev co.
Kev tiv thaiv kev cuam tshuam layout: Thaum xaim, nws yog ib qho tsim nyog kom tsis txhob muaj qhov sib npaug siab - cov kab hluav taws xob ceev thiab cov kab hluav taws xob, nrog qhov sib nrug ntawm ntau tshaj 50mm; Yog tias tsim nyog hla, nws yog ib qho tsim nyog yuav tsum tswj 90℃orthogonality kom txo tau kev sib txuas. Piv txwv li, hauv AGV tsheb, M12 connector yuav tsum tau muab tso rau hauv lub hwj chim cables thiab Ethernet cables, sib cais los ntawm ib tug hlau muab faib nyob rau hauv nruab nrab.
4, Mechanical kev ua tau zoo thiab ib puag ncig adaptability
Cov kev xav tau ntawm kev ntseeg siab rau M12 adapters hauv kev lag luam yog nruj:
Kev co thiab kev cuam tshuam tsis zoo: Cov khoom sib txuas yuav tsum dhau IEC 60068-2-6 tus qauv kev co (5-55Hz, 1.5mm amplitude) thiab IEC 60068-2-27 cuam tshuam kev xeem (50g, 11ms ib nrab sine yoj). Piv txwv li, Pentax stainless hlau plhaub M12 connector tuaj yeem tswj cov teeb liab kev ruaj ntseg thaum lub sij hawm 380km / h high-speed rail khiav lag luam.
Kev tiv thaiv qib: Nws yuav tsum ncav cuag IP67 lossis siab dua txhawm rau tiv thaiv cov plua plav thiab siab - dej siab nkag. Lingke LM12 tivthaiv tau dhau IP69K ntawv pov thawj thiab tuaj yeem tiv taus 80℃dej kem dej ntws tawm hauv qab lub siab ntawm 100bar.
Qhov kub thiab txias: Muaj qib M12 cov khoom sib txuas yuav tsum tau txhawb kev ua haujlwm kub ntawm -40℃mus rau +85℃, thiab cov khoom yuav tsum dhau UL94 V-0 nplaim retardant kuaj. Desao siv PPS engineering yas plhaub, uas tuaj yeem tswj qhov ruaj khov ntawm qhov chaw huab cua xws li -65℃mus rau +125℃.
5, Hlau specifications thiab installation txheej txheem
Kev kub ceev Ethernet cabling yuav tsum ua raws li cov lus qhia nruj kom ua kom lub teeb pom kev ncaj ncees:
Yam tsawg kawg nkaus dabtsi yog khoov vojvoog: Lub vojvoog dabtsi yog khoov ntawm lub cable yuav tsum tsis txhob tsawg tshaj li 8 npaug ntawm txoj kab uas hla kom tsis txhob ua puas lub twisted khub qauv. Piv txwv li, qhov tsawg kawg nkaus khoov vojvoog rau ib txoj kab uas hla 0.5cm yog 4cm.
Los ntawm lub qhov tsim: Thaum PCB thaiv, siab - teeb liab ceev los ntawm qhov yuav tsum tau siv lub tshuab rov qab drilling kom tshem tawm cov seem seem, thiab hauv av los ntawm qhov yuav tsum tau muab tso rau ze ze kom muab txoj hauv kev rov qab. PCB routing ntawm M12 interface nrog X-code yuav tsum tau tswj cov yam ntxwv impedance ntawm 100 Ω thiab qhov yuam kev ntawm ± 10%.
Crimping zoo: Crimping M12 connectors yuav tsum tau siv cov cuab yeej tshwj xeeb los xyuas kom meej tias qhov chaw sib cuag ntawm cov neeg thiab cov tub ntxhais hlau yog ntau dua 80%. Piv txwv li, cov cuab yeej DeSuo crimping tuaj yeem tswj lub zog crimping nyob rau hauv thaj tsam ntawm 20-30N, zam kev sib cuag deformation los ntawm overvoltage.
Kev Tswj Xyuas Tus Kheej: Cables yuav tsum tau sau npe nrog hom coding, tus nqi sib kis, thiab kev khiav dej num kom tsis txhob muaj kev sib txuas tsis raug. Piv txwv li, X-code cables yuav tsum tau sau nrog cov cim daj, D-code cables yuav tsum tau sau nrog cov cim xiav, thiab sau lo lus "10Gbps" lossis "100Mbps".
