RS485-2x22AWG communication cable

RS-485 data cables are used for multi-point communication. Many devices can be connected via a single signal cable, much like early Ethernet was connected using a coaxial cable. RS-485 data cables can be applied to complex building automation, industrial control networks, power automation, and other communication networks.

Section 2: RS485 Cable Product Specifications:

Standard 1st-line RS-485 communication cable, characteristic impedance of 120 ohms, conductors of 2*24AWG multi-strand tinned copper wire, PE insulated medium, 100% covered by aluminum foil/polyester composite tape + 90% covered by tinned copper wire for double shielding, with an independent grounding wire, industrial gray PVC jacket, compliant with UL 2919 document. Exceptional product performance, applicable to complex industrial automation control network communication and building automation network communication.

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

The 9842 model 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: RS-485 communication cables typically use twisted pairs in general conditions, but shielded twisted pairs can be used in higher requirement environments. When using RS485 communication, the cable length between the host (sampling device) and the 485 port of the instrument is inversely proportional to the baud rate of the data signal transmission; this length is mainly affected by signal distortion and noise. Theoretically, with communication rates of 100Kbps or less, the maximum transmission distance for RS485 can reach 1200 meters, but in practical applications, the transmission distance also 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.

Four, Conditions of Use: 1) No mechanical damage, laying temperature: 0~50℃. 2) Operating temperature: -20~60℃. 3) Minimum bending radius during laying: 8 times the cable diameter. 4) Minimum bending radius during laying: Main cable is 6 times the cable outer diameter; Horizontal cable is 4 times the cable outer diameter.
