 RS485 communication cable

Introduction of RS485 data cable and RS485 communication line

I. RS485 data cable RS485 communication line use characteristics: RS-485 data cable is used for multi-point communication. Many devices can be connected via a signal cable. It's just like the old Ethernet was connected by a coaxial line. RS-485 data cable can transmit 1200 meters at the speed of 2.5mb/s, which is used in complex communication networks such as building automation, industrial control network and power automation.

II. Product specification of RS485 data cable and RS485 communication line:

1-pair 2-core (2x24awg) (2 * 0.2) (2 * 0.5) (2 * 0.75) (2 * 1.0) (2 * 1.5) multi stranded stranded tinned copper wire, PE insulation sheath; for complex industrial noise environment, aluminum foil / polyester composite tape 100% shielding rate + tinned copper woven mesh 90% shielding rate is adopted, with independent TC grounding conductor, industrial gray PVC outer sheath, characteristic impedance of 120 ohm.  

2-wire to 4-core (2x 2x24awg) (2 * 2 * 0.2) (2 * 2 * 0.5) (2 * 2 * 0.75) (2 * 2 * 1.0) (2 * 2 * 1.5) multi stranded stranded tinned copper wire, PE insulation sheath; for complex industrial noise environment, aluminum foil / polyester composite tape 100% shielding rate + tinned copper braided net 90% shielding rate is adopted, with independent TC grounding conductor, industrial gray PVC outer sheath, characteristic impedance of 120 ohm.  

3. RS-485 communication cable can use twisted pair cable in general occasions, but it can use twisted pair cable with shielding layer in high requirement environment. When RS485 communication is used, the length of cable between host (test equipment) and 485 port of instrument is inversely proportional to baud rate of data signal transmission for specific transmission line; this length is mainly affected by signal distortion and noise. In theory, the transmission distance of RS485 can reach 1200 meters, but in practical application, the transmission distance is less than 1200 meters. The specific length of RS485 data cable and RS485 communication line is affected by the surrounding environment. 4、 RS485 data cable RS485 communication line can be made into armored RS485 cable (steel belt armor or steel wire armor) according to the user's requirements. It is mainly used for underground use. It can prevent the cable from being damaged by external mechanical force in harsh environment.
