NI SH68-68-EP Shielded Digital Wire (2 m)
68-pin D-SUB female to 68-pin D-SUB female, twisted pair, shielded multifunction cable - SH68F-68F-EPM cable, sometimes called SH68-68-EPM, is used to connect NI DAQ 68-pin devices to 68-pin accessories. SH68F-68F-EPM cables have D-type connectors and are available in different lengths.
How twisted pair works
The working principle of SH68-68-EP twisted pair is mainly based on the reduction of electromagnetic interference and the suppression of signal attenuation:
Reduction of electromagnetic interference: The SH68-68-EP twisted pair consists of two wires twisted together, which generate an electric current from each other and form a magnetic field when transmitting signals. This magnetic field can effectively counteract electromagnetic interference generated by other electronic devices, thereby reducing the impact of electromagnetic interference on data transmission.
Suppression of signal attenuation: Each wire in the twisted pair is composed of multiple copper wire filaments, which are tightly twisted together to form a more robust structure, which helps to reduce the energy loss of the signal during transmission and maintain the stability and clarity of the signal.
Third, the application of twisted pair
SH68-68-EP twisted pair wire is widely used in a variety of communication, network and television equipment because of its excellent performance:
Telephone system: used to transmit voice signals, with strong anti-interference ability, high signal transmission quality, good reliability.
Computer network system: SH68-68-EP is used to transmit digital signals, especially Ethernet and other twisted pair based networks, with fast transmission speed, strong data confidentiality, strong anti-interference ability.
TV signal transmission system: used to transmit video signals, wide frequency transmission range, suitable for transmitting high-definition video signals, high signal transmission quality.
Sound system: can be used to transmit audio signals, transmission effect is stable, good effect, high popularity.
Four, the advantages and disadvantages of twisted pair
Advantages:
Low price, convenient materials.
The transmission distance is moderate, suitable for short distance and small range of data transmission.
Strong anti-interference ability, high signal transmission quality.
Cons:
Compared with the transmission medium such as optical fiber, the transmission distance and data transmission speed of twisted pair are limited.
In strong electromagnetic interference environments, additional shielding measures may be required to ensure data transmission quality.
