A shielded cable is an electrical cable of one or more insulated conductors enclosed by a common conductive layer. The shield may be composed of braided strands of copper a non-braided spiral winding of copper tape, or a layer of conducting polymer. Usually this shield is covered with a jacket.
Industrial applications such as the factory floor are typically electrically noisy environments. Electrical noise, either radiated or conducted as electromagnetic interference (EMI), can seriously disrupt the proper operation of other equipment. Shielding , including braid and foil wraps, reduces electrical noise and its impact on signals while lowering electromagnetic radiation and cable crosstalk.
When cable assemblies are used in noisy environments, multiple shielding layers are often employed. Most common would be the use of both a foil and a braid. The choice of a shielded cable or non- shielded cable often comes with experience. The electrical environment around the area you are installing the cable determines what is the best choice for that job.
If you want to hide a sensor, but to avoid all the side-effects from the connection. Learn how to use a shielded cable to add stability to your project. Here is a list of connectors for high-speed shielded cable and inter-cable connection. Many translated example sentences containing shielded cable – Russian- English dictionary and search engine for Russian translations.
When installing or updating your network infrastructure, there are a variety of network patch cable types to consider.
Among the choices to be made is whether to install shielded twisted pair cables (STP) or unshielded twisted pair cables ( UTP). Twisted pair cabling consists of two conductors of a single . National Instruments shielded cables are designed and manufactured to provide maximum performance and noise immunity. These cables feature separate digital and analog sections, a double-grounded shiel individually shielded analog outputs, individually shielded twisted pairs for all anaput, and twisted pairs . A well-engineered cable is comprised of many crucial independent elements. Recently shielding has become just as critical as any other design element.
There are many options available when purchasing cables. How do you know which one is right for you? One of the most common types of cable you might find are shielded cables. Types of cables that come in shielded versions include Ethernet cables, coaxial cables, . Shielded cables are a necessity for some applications.
Cables shield are seldom solid tubes, welded at each end to the system boxes or sub assemblies (exception accounted for semi-rigid coax and some very specific military systems). Yet, the concept of a conductive sheath surrounding the wires can still be achieved by other constructions. Online shopping from a great selection at Electronics Store.

Why do cables have shields? To prevent signals in cables from radiating and causing interference. To maintain controlled impedance so that fast-changing signals can travel.
Cables and connectors are shielded to reduce the risk of EMI. Learn more about what makes this so important for your products.
