RS485-2x18AWG Signal 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.

Section 2: RS485 Cable Product Specifications:

Exceptional product performance, suitable for complex industrial automation control network communication and building automation network communication.

Standard 2-pair RS-485 communication cable with characteristic impedance of 120 ohms, conductor: 2-pair 4-core (2x2x24AWG) multi-stranded tinned copper wire, PE insulated sheath; designed for complex industrial noise environments, features 100% foil/polyester composite shielding + 90% shielding with tinned copper braid, accompanied by an independent TC grounding conductor, industrial gray PVC outer sheath, compliant with UL AWM 2919 specification.

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 networks, but also a standard 2-pair CAN bus cable.

Section 3: RS485 Cable Application Range: RS-485 communication cables typically use twisted pairs in general applications, but shielded twisted pair cables are recommended for higher-demand environments. When using RS485 communication, the cable length between the host (sensing device) and the instrument's 485 port is inversely proportional to the data signal baud rate; this length is primarily affected by signal distortion and noise. Theoretically, with communication rates of 100Kbps or less, the maximum RS485 transmission distance is 1200 meters. However, 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, up to a maximum of eight, meaning the theoretical maximum transmission distance for RS485 can reach 9.6 kilometers.
