QWhat is Flexible Cable?AWhat is Flexible Cable?
Flexible Cable is a cable that possesses flexibility for challenging cable positioning. We defines "flexibility" as "that quality of a cable or cable component which allows for bending under the influence of outside force."
How many types of cable flexing are there?
There are four common types of cable flexing movements. These include rolling flex, bending flex or "tic-toc," torsional flex and variable/random motion flex. Usually flexible cable are some kinds of rubber cable, control cable, instrument cable, welding cable and mine cable etc.
In what types of applications would I use Flexible Cable?
Flexible Cable is utilized in numerous applications to withstand the extreme stress of flexing and motion. A few applications include: drag chain applications, applications with repetitive bending and torsion stress, machine tools, data processing equipment, robotics, assembly lines, automation networking, microprocessor and computer interconnects and many more.
Do Flexible Cables meet industry standards?
Flexible Cable styles meet various approvals. Flexible Cable may be UL Listed, CSA certified, CE marked and/or meet military specifications. However, every flexible cable is different, so make sure to specify if your flexible cable needs one or more standards to be met.
QAre instrument cables used for high-impedance or low-impedance lines?AGenerally, the source impedance is the determining factor in cable selection. Instrument cables are used for a wide range of sources. Many keyboard instruments, mixers, and signal processors have very low (50 to 600ohm) source impedances. On the other hand, typical electric guitar or bass pickups are very inductive, very high impedance (20,000 ohms and above) sources. Typical load impedances are greater than 10,000 ohms, which limits the electrical current flow to a very small amount on the order of a few thousandths of an ampere(milliamps).
QHow much power does an instrument cable have to carry?AThe voltages encountered range from a few millivolts, in the case of the electric guitar, to levels over ten volts delivered by line-level sources such as mixers. By Ohm’s Law this represents power levels of less than a thousandth of a watt.
QWhat kind of frequency response does an instrument cable need? What are the lowest and highest frequencies produced by the source?AThe bandwidth spans the entire audible range of frequencies, from the 41 Hz (and below) of bass guitar and synthesizer to the 20 kHz harmonics of keyboards and cymbals. Recording applications demand wide bandwidth to preserve the “sizzle” of a hot performance. Even an electric guitar has a bandwidth of about 82 Hz to above 5 kHz.
QHow big does an instrument cable need to be? will a bigger cable sound better? Will a bigger cable last longer?AIn order to be compatible with standard 1/4-inch phone plugs the diameter of the cable is effectively limited to a maximum diameter of about 265". Larger cable diameters demand larger plug barrels, which sometimes won't fit jacks that are located close together or in tight places. In terms of both sound and durability, "it's not how big you make it, but how you make it big”.
QWhat are the basic parts of an instrument cable and what does each one do?AThe coaxial configuration is generally used for unbalanced instrument cables. At its simplest it consists of a center conductor, which carries current form the source, separated by insulation from a surrounding shield, which is also the current return conductor necessary to complete the circuit. These three components are augmented by an electrostatic shield to reduce handling noise and an outer jacket for protection and appearance.
