Ib, Txuj Ci Txuj Ci: Ntiaj teb kev sib koom ua ke electromagnetic tiv thaiv tus qauv
Electromagnetic compatibility tsim ntawm M12 cable adapters nruj me ntsis raws li IEC 61076-2-101/104 tus qauv tsim los ntawm International Electrotechnical Commission (IEC), uas qhia txog kev tiv thaiv electromagnetic (EMS) thiab radiated emission (EMI) txwv rau kev lag luam connectors. Piv txwv li, D code (industrial Ethernet) thiab X code (10Gbps Ethernet) qauv yuav tsum tau ua raws li cov kev cai ntawm IEC 61000-6-2 (industrial ib puag ncig tiv thaiv) thiab IEC 61000-6-4 (kev lag luam ib puag ncig hluav taws xob) kom ruaj khov cov ntaub ntawv kis tau tus mob txawm nyob rau hauv RF teb cuam tshuam ntawm 10V/m.
Noj LM12 series ntawm Lingke Electric ua piv txwv, nws X-code adapter txais yuav rau txheej tiv thaiv txheej txheem:
Hlau plhaub shielding: Lub plhaub tooj liab alloy zoo cuam tshuam cov hluav taws xob sab nraud;
Internal shielding npog: Tin plated tooj liab ntawv qhwv nyob ib ncig ntawm tus neeg nqa khoom tiv thaiv kev cuam tshuam ntawm cov khoom siv sab hauv;
Cable shielding txheej: ob npaug - txheej shielding ntawm txhuas ntawv ci thiab woven mesh, nrog ib tug attenuation tus nqi ntawm 80dB (1GHz zaus band);
Locking ntsia hlau grounding: Txuas lub shielding txheej rau cov khoom casing los ntawm threaded kev twb kev txuas los ua ib tug tiav shielding Circuit Court.
Qhov kev tsim no ua rau LM12 kom tso tawm cov hluav taws xob qis dua -60dB μ V / m nyob rau hauv ntau zaus ntawm 100MHz txog 1GHz, deb ntawm CISPR 32 Class B txwv, ua rau nws tsim nyog rau kev cob qhia automotive vuam rhiav thiab tsheb ciav hlau cov teeb liab nrog hnyav electromagnetic ib puag ncig.
2, Shielding Design: Los ntawm Kev Tiv Thaiv Passive mus rau Active Optimization
1. Kev tiv thaiv sib txawv ntawm coding system
M12 ua tiav kev sib cais ua haujlwm thiab cuam tshuam kev cuam tshuam los ntawm kev encoding system:
D encoding (100Mbps Ethernet): siv 4-pin sib txawv teeb liab kis tau tus mob, siv hom kev tsis lees paub txoj cai los tshem tawm cov suab nrov sab nraud, haum rau PROFINET thiab EtherCAT tsheb npav;
X encoding (10Gbps Ethernet): 8-pin tag nrho shielded tsim, txhawb PoE++(90W fais fab mov), cais cov teeb liab ceev ceev los ntawm lub hwj huam mov los ntawm kev ywj pheej shielding kab noj hniav kom tsis txhob muaj cov ntaub ntawv jitter los ntawm lub hwj chim hloov;
A-code (sensor teeb liab): 3-pin / 4-pin layout, siv cov impedance tsawg (tsawg dua los yog sib npaug li 50m Ω) kom txo tau crosstalk ntawm cov teeb liab kab thiab xyuas kom meej 4-20mA analog kis tau tus mob.
2. Kev tsim kho tshiab hauv cov khoom siv thiab cov txheej txheem
Niaj hnub nimno M12 adapters txhim kho kev tiv thaiv zoo los ntawm kev hloov khoom dua tshiab:
Amorphous alloy shielding txheej: Cov cobalt raws li amorphous alloy siv los ntawm Lingke Electric muaj qhov sib nqus permeability peb zaug ntawm cov tshuaj ferrite, uas tuaj yeem nqus tau tsawg- zaus sib nqus teb cuam tshuam;
Nano txheej thev naus laus zis: Txau cov khoom siv nanoparticles rau ntawm phab ntsa sab hauv ntawm lub plhaub hlau los ua cov txheej txheem ultra-thickness (thickness tsawg dua lossis sib npaug li 5 μ m), txo cov tawv nqaij ntawm qhov siab - zaus electromagnetic tsis;
Integrated molding txheej txheem: METZ CONNECT's M12 adapter txais kev txhaj tshuaj molding tshuab, tshem tawm qhov tsis sib xws hauv cov txheej txheem sib dhos thiab txhim kho kev tiv thaiv txuas ntxiv los ntawm 90%.
3, Daim ntawv thov scenario: Electromagnetic tiv thaiv yuav tsum npog tag nrho cov kev lag luam saw
1. Intelligent manufacturing kab ntau lawm
Hauv kev cob qhia automotive welding, M12 adapters yuav tsum tau nrog 2.4GHz siab- zaus cuam tshuam los ntawm cov tshuab plasma thiab cov pulses ib ntus tshwm sim los ntawm arc sparks. Lingke LM12-X series ua tiav kev sib kis tau ruaj khov los ntawm cov qauv hauv qab no:
Transient Voltage Suppressor (TVS): Kev sib koom ua ke ntawm 15kV surge tiv thaiv ntaus ntawv nruab nrab ntawm cov teeb liab kab thiab hauv av kom nqus tau cov overvoltage;
Filter capacitor array: Txuas 0.1 μ F thiab 10 μ F ceramic capacitors nyob rau hauv parallel ntawm lub hwj chim tus pin kom lim tawm suab nrov nyob rau hauv ntau zaus ntawm 10kHz txog 10MHz;
Kev sib kis tsis tu ncua: Hauv 8-pin tsim qauv ntawm X encoding adapter, 4 tus pins yog siv rau cov ntaub ntawv xa mus, 2 tus pins yog siv rau cov khoom siv hluav taws xob, thiab 2 tus pins yog siv los ua cov txheej txheem thaub qab los txhim kho qhov kev ua txhaum cai.
2. Rail Transit Signal System
Lub traction fais fab mov system nyob rau hauv lub subway tunnel generates ib tug muaj zog low -frequency magnetic field (50Hz power zaus thiab nws harmonics), uas cuam tshuam cov teeb liab kis tau tus mob. D-code M12 adapter teb los ntawm cov thev naus laus zis hauv qab no:
