RS485 Communication Cable, 2x1.0 Shielded Signal Wire, 485 Communication Line

The RS-485 data cable is used for point-to-point communication. Many devices can be connected using a single signal cable, much like earlier Ethernet was connected using a coaxial cable. The RS-485 data cable can be used in complex building automation, industrial control networks, power automation, and other communication networks.

The 9842 communication cable is a standard product designed and manufactured strictly according to the RS-485 communication protocol specifications. It is not only the designated model for Rockwell (AB) automation DH-485 control network but also a standard 2-pair CAN bus cable.

Three, Application Range of RS485 Cable: For general conditions, a twisted pair cable is sufficient for RS-485 communication cables. However, in higher-demand environments, shielded twisted pair cables can be used. When using RS485 communication, the cable length between the host (measurement device) and the instrument's 485 port is inversely proportional to the baud rate of the data signal transmission; this length is mainly affected by signal distortion and noise. Theoretically, at communication rates of 100Kbps or less, the maximum transmission distance for RS485 can reach 1200 meters. In practical 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.
