The RS485 communication cable Heller Teng specialty wire and cable Co., Ltd.

RS-485 communications cable telephone 13626190989 QQ55107402 main application in high demand environments, such as complex industrial noise environments when using RS485 communication medium, for a particular transmission line, the host (called DUT) to 485 meter between the cable length and the transmission rate is inversely proportional to the data signal; this length is mainly influenced by the distortion and the effect of noise signals. Theoretically RS485 transmission distance can reach 1200 meters, but the practical application of the transmission distance is less than 1200 meters, the surrounding environment by a specific length. If you need transmission over longer distances, you need to add 485 repeater implementation of standards: compliance with UL AWM 2919 file specification. ■ RS-485 communication cable product mix: conductor stranded tinned copper wire, PE dielectric, aluminum foil / polyester composite with 100% coverage + 90% tinned copper shield covering a total of 2 floors, with independent Ground wire (tinned copper conductor), the characteristic impedance of 120 ohms, industrial gray PVC outer sheath. ■ Performance:: 1, strong anti-interference performance. 2, long transmission distance; 3, RS-485 is used for multi-point interconnection is very convenient, you can save a lot of signal lines. ■ Knowledge: RS-485 American Wire Gauge AWG and Metric, Imperial table RS-485 transmission distance ■ Model: commonly used models for the 24AWG, 26AWG, there is a line pair, 2-wire pair, 3-wire pair, 4 pair special requirements can be customized conductor have 0.2mm2,0.5mm2,0.75mm2,1.00.75mm2
