Twisted pair wire is a communication technique as old as electrical engineering. Twisted pair that is accurately twisted makes a big difference in the signal.
RS485 is used for LAN and CAN protocol. Accurately twisted pair places no strain on the wire and yet the wire does not want to unravel.
Often used for RS232 9 pin 5 volt and -5 volt systems. Current sensors. lamp wire and many other electrical applications.
Twisted wire made accurately and save lives in autonomous vehicles and autonomous transportation.
Controlling the pitch, or the distance between the twists in twisted pair cables, is crucial for several technical reasons, all of which contribute to the overall performance and effectiveness of the cable in various applications. Here are the main reasons why the control of twist pitch is important:

Minimizing Crosstalk: Crosstalk is the interference caused by signals in adjacent wires or cables. By carefully controlling the twist pitch, manufacturers can reduce the crosstalk between pairs within the same cable. The twist helps to balance the electromagnetic fields between the wires in the pair, thereby reducing the potential for signal interference from one pair to another. Consistent and tight twists are particularly effective in minimizing this effect.
Reducing Electromagnetic Interference (EMI): The twisting of wires helps to cancel out electromagnetic interference from external sources. By adjusting the pitch, one can fine-tune the level of immunity to EMI. Different pitches may be better suited to different environments based on the level and type of external electromagnetic noise.
Maintaining Impedance Consistency: The impedance of a cable is influenced by the physical arrangement of the wires. Consistent twisting helps maintain a uniform impedance along the length of the cable, which is important for signal integrity, particularly in high-frequency transmissions such as data communications.
Enhancing Signal Integrity: A consistent twist pitch helps in maintaining phase relationships and timing within the communication signals, which is critical for high-speed data transmission. Irregular twists can lead to phase shifts and timing errors, adversely affecting the data integrity.
Physical Cable Properties: The pitch can also influence the physical properties of the cable, such as flexibility and tensile strength. A tighter twist might make the cable stiffer, whereas a looser twist could provide more flexibility but might be less effective at interference cancellation.
Optimizing Frequency Response: Different applications might require different frequency responses, which can be influenced by the twist pitch. For example, cables used in high-frequency applications might benefit from a tighter twist to ensure a broader bandwidth and reduced signal loss.
In summary, controlling the twist pitch in twisted pair cables is essential for optimizing their performance in terms of reducing interference, maintaining consistent electrical properties, and ensuring robust data transmission. It allows manufacturers and engineers to design cables tailored to specific environments and requirements, enhancing the reliability and functionality of communication networks.
