How to choose the right cable? The increasing number of smart sensors, I/O devices, data acquisition and communication systems, as well as various power supplies, robots, and processing equipment, makes the selection of connections and cables increasingly complex. Choosing a cable is usually quite easy. Users use them for communication, control, or to provide power. They add accessories, chassis and brackets, as well as connectors to suit the layout, improve usability, and address environmental protection, such as protection against chemicals/oils, as well as shielding/interlock protection. Because standard connection cables or multi-core twisted pairs are still the most widely used cables at present. These basic standards remain very important. However, the increasing use of smart sensors, I/O devices, data acquisition and communication systems, as well as various power supplies, versatile robots, and processing equipment, is making the selection of connections and cables increasingly complex. Of course, choosing the right cable isn’t that mysterious either. For non-stationarity, communication, or more traditional wiring and cables, there are 8 main options. Including continuous flex ； Torsional robotic ； servo ； Control ； Data bus ； European standards for wires, cables, and optical fibers ； European Unitronic line ； As well as cables for lifting and conveying systems. Cable types and connection methods for various frequency drives, optical fibers, and other specialized applications must be used according to their respective characteristics. Continuous flex cables are designed for high-speed automation applications, such as industrial robots, pick-and-place machines, operating systems, machining, and conveying systems. Standard control cables are used in these applications, but they are not suitable for continuous extension and retraction, as they require a minimum of 5 to 10 million rotations. The telescopic cable can move at a speed of 6.5–13 ft/sec, with an acceleration of up to 25 ft/sec. Continuous telescoping cables are made of elastic materials, allowing them to quickly return to their unstressed state after each extension and retraction cycle. Its copper core must have good ductility (not exceeding grade 34), which helps with movement and the reduction of connections. When selecting and installing continuous telescopic cables, users must pay attention to their bending radius. It indicates the degree of tension in the corner (usually with a diameter of 12 x, or less); within this range, there is no loss of elastic memory or other forms of damage. Users must also pay attention to the service life. Torsional robotic cables are used in applications that involve twisting and bending; they help reduce failures and fatigue, and their service life can typically exceed 2 million rotations. It must also operate under the requirements specified for standard cables regarding temperature, voltage, and degree of aging. There are 3 types of servo cables in one cable: for power, signals, and control of the servo motor. To enable accurate movement at both long and short distances. Servo systems require cables with high expansion/contraction cycle times, as well as cores of different gauges. The power core drives the motor, which controls the core to perform the designated movements. Servo motors often need to operate in an electromagnetic interference shielding (EMI) environment to avoid disturbances to control and feedback signals. Control cables allow data transmission. Shielded cables of medium and small sizes in this type of cable typically require a voltage of 115 V ac or 24 V dc; they are sometimes also referred to as “electronic wire”. Data bus cables transmit information at high speeds and with high bandwidth; the information is transferred within the network that connects the underlying devices and the control system devices, without the need for input/output interfaces. European wire is used for equipment exported to Europe; it complies with the standards set by the European Committee for Electrotechnical Standardization (CENELEC), meets CE standards, and is suitable for power cables and connection wires. European Unitronic electronic cables are multipair cables, and they also comply with European standards such as VDE and DIN. Used in electronics, communications, process control, and instrumentation applications
