RS485 communication line RVSP 18/20/24 RVVPS signal line shielded
cable double twisted double screen communication line
1.Product description
RS485 communication line in the general use of twisted pair can be,
but in the higher requirements of the environment to use with
shielding layer of twisted pair cable. When RS485 communication
line is used, for a specific transmission line, the length of the
cable between the host (call test equipment) and the meter is
inversely proportional to the baud rate of data signal
transmission; This length is mainly affected by signal distortion
and noise. Theoretically, the transmission distance of RS485
communication cable can reach 1200 meters, but the transmission
distance in practical application is less than 1200 meters, and the
specific length is affected by the surrounding environment.
RS485 communication cable features: RS-485 communication cable
features impedance of 120 ohm, conductor of 2*24AWG multi-strand
stranded tinned copper wire, PE insulation medium, by aluminum
foil/polyester composite with 100% coverage + tinned copper wire
90% coverage of a total of 2 layers of shielding, with independent
grounding wire, industrial gray PVC outer sheath.
Feel free to contact with us, if you ever needed to consider your
wire harness solution.

coverage of 55%.
VII: Inner sheath: black PVC, OD: 8.0mm +/- 10%.
The tested RS485 communication line communication distance is about
1219M, the transmission rate is 10Mb/S, the transmission rate and
the transmission distance are inversely proportional, under the
transmission rate of 100Kb/S, to achieve the communication
distance, if you need to transmit a longer distance, need to add
485 repeater. RS485 bus generally supports 32 nodes, if the use of
special 485 chip, can reach 128 or 256 nodes, can support to 400
nodes.
Because RS485 interface has good anti-noise interference, long
transmission distance and multi-station ability and other
advantages make it a serial interface. Because RS485 interface
composed of half duplex network, generally only two connections, so
RS485 interface are shielded twisted-pair transmission.
