简单介绍
RS485专用电缆-20X12AWG和专用电缆是我厂产品，购买我厂RS485专用电缆-20X12AWG和专用电缆请联系销售部。
产品描述
在低速、短间隔、无搅扰的场所可以采用通俗的双绞线，反之，在高速、长线传输时，则必需采用阻抗匹配（普通为120Ω）的RS485专用电缆（STP-120Ω（for RS485 & CAN） one pair 18 AWG），而在搅扰恶劣的情况下还应采用铠装型双绞屏障电缆（ASTP-120Ω（for RS485 & CAN） one pair 18 AWG）。在运用RS485接口时，关于特定的传输线路，从RS485接口到负载其数据旌旗灯号传输所答应的较大电缆长度与旌旗灯号传输的波特率成反比，这个长度数据首要是受旌旗灯号掉真及噪声等影响所影响。理论上，通讯速度在100Kpbs及以下时，RS485的*长传输间隔可达1200米，但在实践使用中传输的间隔也因芯片及电缆的传输特征而所差别。在传输进程中可以采用添加中继的办法对旌旗灯号进行扩大，*多可以加八个中继，也就是说理论上RS485的较大传输间隔可以到达9.6公里。假如真需求长间隔传输，可以采用光纤为传达介质，收发两头各加一个光电转换器，多模光纤的传输间隔是5~10公里，而采用单模光纤可达50公里的传达间隔。
