Quotation for selling twisted pair shielded cables

“Yinshun brand "brand wire and cable factory construction1972In the year, we produce a series of cables for coal mines, including rubber sheathed cables, computer cables, control cables, high-voltage cables, and more. We serve our customers with the concept of strict production and factory inspection. Welcome friends from all walks of life to call or write letters, and conduct on-site inspections and visits.

Twisted pair shielded cableTwisted pair shielded cable

RS485/22Communication cable voltage300VThe necessary power supply for lighting, power tools, etc., and the ability to simultaneously transmit various control signals,DC voltage1000VTransmission of audio signals, as well as fixed railway signals and transmission control lines for certain automatic devices. Currently widely used for centralized meter reading signal transmission in smart meters.

RS485In general, twisted pair cables are sufficient for communication lines, but in environments with higher requirements, shielded twisted pair cables should be used. useRS485When using communication lines, for specific transmission lines, the host(Call testing equipment)To the instrument485The length of the cable between ports is inversely proportional to the baud rate of data signal transmission; This length is mainly affected by signal distortion and noise. theoreticallyRS485The transmission distance of communication cables can reach1200Meter, but in practical applications, the transmission distance should be less than1200The specific length of meters is affected by the surrounding environment.
