低电容，高串扰衰减
屏蔽，Termi-Point? 

应用领域
CC-data cable PiMF Li2YCY-270 屏蔽，用于EDP和控制设备中的数据和信号传输。PE芯线线对确保了数据的大规模传输。线对的金属箔屏蔽促进大量的串扰衰减。整体镀锡铜丝屏蔽确保了数据以及脉冲的可靠传输，以保护不受电干扰。其可以用于剪切和夹具技术以及 Maxi-Termi-Point?* 连接技术。
application
The CC-data cable PiMF Li2YCY-270 shielded is used to transfer data and **s in EDP and control equipment. Polyethylene core pairs ensure the transfer of large quantities of data. The metal foil shielding of the pairs facilitates a considerable high crosstalk attenuation. The overall tinned copper shield ensures a reliable transmission of data or respectively impulses at the same time protecting against electrical interference. It is intended to be used in cutting and clamping technology as well of Maxi-Termi-Point?* link-up technology.
