Qhov kawg Guide to Shielded vs UnshieldedM12 Cables:Kev xaiv tseem ceeb rau cov ntawv thov kev lag luam
Nyob rau hauv ib puag ncig kev lag luam hnyav xws li automation, robotics, thiab sensor networks, qhov kev xaiv ntawm cov shielded thiab unshielded M12 cables cuam tshuam qhov teeb meem kev ncaj ncees thiab cov khoom siv ntev. Qhov kev ntsuam xyuas dav no nthuav tawm lawv qhov sib txawv tseem ceeb nrog cov lus pom zoo.
Qhov sib txawv ntawm cov qauv: Yuav ua li cas thaiv kev hloov pauv Cable kev ua tau zoo
Shielded M12 cables feature dual- txheej tiv thaiv:
Inner layer: Aluminum foil shielding around pairs, absorbing >90% ntawm siab - zaus cuam tshuam
Txheej txheej: Tinned tooj liab braid rau txhua yam kev tiv thaiv thiab txhim kho hauv av
Cov lus qhia tshwj xeeb: Cat6A ntsuas, txhawb 10Gbps txog 100m
Unshielded M12 cables siv optimized twisting technology:
4 khub nrog tshwj xeeb twist piv rau theem tshem tawm
UV- tsho tiv thaiv rau sab nraum zoov
Tus nqi kom zoo dua: ~ 35% tsawg dua li cov khoom siv tiv thaiv
Kev sib piv kev ua tau zoo: 5 Cov Kev Ntsuas Tseem Ceeb
EMI Resistance
Shielded: me ntsis yuam kev tus nqi<10^-12 near VFDs
Unshielded: BER ncav cuag 10^-8 nyob rau tib lub sijhawm
Teeb liab attenuation
Shielded: 24dB @ 250MHz rau 100m
Unshielded: 32dB @ 250MHz
Khoov Radius
Shielded: Yam tsawg kawg nkaus 8x cable txoj kab uas hla
Unshielded: tuaj yeem khoov rau 6x txoj kab uas hla
Qhov kub thiab txias
Tiv thaiv: -40℃rau +85 degree
Unshielded: -30℃rau +70 degree
Kev tiv thaiv ntsuas
Shielded: IP67 / IP69K nrog tshwj xeeb connectors
Unshielded: IP65 tus qauv
Tsob ntoo txiav txim rau daim ntawv thov scenarios
High EMI ib puag ncig (piv txwv li, vuam neeg hlau hlwb)
→ Xaiv ob -shielded (SF/UTP)
→ Pom zoo: Lapp Group Unitronic series
Cov khoom siv txawb (xws li AGVs)
→ Xaiv tsis muaj kev tiv thaiv nrog lub caij nplooj ntoos hlav tiv thaiv
→ Pom zoo: Hirose HR series
Kev teeb tsa sab nraum zoov (xws li cua turbine sensors)
→ shielded cables yuav tsum tau waterproof connectors
→ Tus nqi cuam tshuam: +40% vs cov kev daws teeb meem sab hauv
Installation Cov kev coj ua zoo tshaj plaws
shielded cables yuav tsum muaj ib qho -point grounding
Khaws 30% qhov sib piv rau cov kab hluav taws xob uas tsis muaj kev tiv thaiv hauv cov kav dej
Avoid parallel routing with power cables >1m
