RS485-2x24AWG Flame Retardant Communication Cable

The RS-485 data cable is used for communication between multiple points. Many devices can be connected using a single signal cable, similar to how early Ethernet used a coaxial cable. The RS-485 data cable can be utilized in complex building automation, industrial control networks, power automation, and other communication networks.

9842 Communication Cable, a standard product strictly designed and manufactured in accordance with the RS-485 communication protocol specifications, is not only the designated model for Rockwell (AB) Automation's DH-485 control network, but also a standard 2-pair CAN bus cable.

Three, RS485 Cable Application Range: RS-485 communication cables typically use twisted pairs in general environments, but shielded twisted pairs can be used in higher-demand settings. When using RS485 communication, the cable length between the host (sampling equipment) and the 485 port of the instrument is inversely proportional to the data signal baud rate; this length is mainly affected by signal distortion and noise. Theoretically, with communication speeds of 100Kbps or less, the maximum RS485 transmission distance can reach 1,200 meters. However, in actual applications, the transmission distance varies due to the transmission characteristics of the chip and cable. During transmission, signal amplification can be achieved by adding repeaters, with a maximum of eight repeaters, meaning the theoretical maximum transmission distance for RS485 can reach 9.6 kilometers.
