OMG, yes. You must use twisted pair, and shielded twisted pair will help with reliability. Standard impedance for twisted pair is typically 100 – 120 ohms, but the exact impedance is unimportant. What is important is that the cable HAS an impedance, and the terminating resistors at each end of the cable match the cable impedance.

Simply take an eight-port, push-in type wire connector, add your new grounding wire to it, and then untwist each equipment grounding wire from its existing bundle and push it into a hole on the connector. Once you’re done, all the bare equipment grounding wires should be in the push-in connector, connected together. Share.
Should I twist DC power and ground wires from a power supply?
Twisting wires reduces the magnetic loop area of the wires, this has two implications: Reduced susceptibility to noise from magnetic fields, with twisted wires an a smaller magnetic loop area, external magnetic fields will induce less current in the loop made by the wires than straight cables. Reduced magnetic radiation from loads that are …
When should twisted pair wires be used?
As an example, I understand the use of a twisted pair in differential signaling. This helps reduce noise because both wires receive the same interference which can then be removed by a differential amplifier. I also remember reading quite a while ago about an induction forge where the power output was significantly lower than anticipated.

Twisted pair – Wikipedia
A twisted pair can be used as a balanced line, which as part of a balanced circuit can greatly reduce the effect of noise currents induced on the line by coupling of electric or magnetic fields. The idea is that the currents induced in each of the two wires are very nearly equal. The twisting ensures that the two are on average the same …

CAN Bus Cable: What They Are and How They Function
20 janv. 2024Bus can cable is designed following CAN Open and ISO 11898 standards for high reliability, flexibility, and efficient use of network bandwidth. Flexible CAN bus cables are abrasion- and cut-resistant, and are typically twisted-pair to provide common-mode noise immunity. Although CAN bus cables originated in the automotive field, they are now …

The Importance of Using Twisted Pair Wiring for Can Bus Systems
A CAN bus system consists of one or more nodes, which can be microcontrollers, sensors, or actuators, connected together through a twisted pair wiring. The wiring consists of two wires, a CAN high (CANH) wire and a CAN low (CANL) wire, which are used for data transmission. The CAN bus system operates on a priority-based, message-oriented protocol.

Twisted Pairs: Why are Wires Twisted? – Audio University
Twisted Pairs Reduce Outgoing Noise. Placing the wires next to one another will greatly reduce the energy of the magnetic fields created by each wire. That’s because the positive wire creates a positive magnetic field and the negative wire creates a negative magnetic field. The two magnetic fields interact and work against one another.

CAN wiring needs twisted pair or not – Page 1 – EEVblog
If anything is high-speed or high-voltage it will couple into the CAN lines. That is one place where the twisted pair would help. Industrial CAN communication cables that carry DC power usually have the power pair twisted and screened, with the CAN lines twisted in a separate screen, all of which is then in yet another screen or braid with a drain.

What is twisted pair cable and why is it important?
21 janv. 2023That ought to be enough for a while. Beyond that, you can already wire with fiber optics. With fiber, you can have speeds 1,000 times faster than even the fastest twisted pair, in a single strand of fiber the width of a human hair. I’ll tell you what could happen though. You could have a need for pair cables or fiber.

Twisted Pair Cable: Unraveling the Essentials of Network Wiring
20 déc. 2023A twisted pair cable consists of pairs of insulated copper wires twisted together. Each pair comprises two conductors, typically copper wires, encased in color-coded insulation. The twisting of the wires serves a vital purpose: it reduces electromagnetic interference (EMI) and crosstalk between adjacent pairs and external sources.

The different twist rates are why you’ll see different lengths for each pair when you measure the length of each with a cable tester. If you were to untwist them and stretch them out flat, the ones with more twists would be a little bit longer. Length can differ by 5% or more – the TIA limit for cabling length is based on the shortest pair.
