A conductive foil or braid that covers insulated wires in a cable. The shield provides electrical grounding and protection from external electromagnetic interference (EMI). Shielding is also used to control internal electromagnetic radiation.

Keeps a conductor or equipment away from interference.

Protects other equipment from interference derived from the drive units magnet.

shield consisting of an arrangement of metal mesh or plates designed to protect electronic equipment from ambient electromagnetic interference

The electric or magnetic materials used in a cable that protect its signal from unwanted noise.

A substance or device that attenuates electric or magnetic fields.

A metal foil or mesh surrounding a conductor to reduce electromagnetic interference.

The process of applying a conducting barrier between a potentially disturbing noise source and electronic circuitry. Shielding may be accomplished by the use of metal barriers, enclosures, or wrappings around source circuits and receiving circuits.

The use of conducting material to form a barrier to EM waves, so that they are reflected or absorbed.

The practice of confining the electrical field around a conductor to the primary insulation of the cable by putting a conducting layer over and/or under the insulation. (External shielding is a conducting layer on the outside of the insulation. Strand or internal shielding is a conducting layer over the conductor itself).

Insulation using a grounded, metallic covering to protect a cable or wire against interference.

One of the three components of TDS.  Shielding refers to maintaining significant physical barriers between you and the hazard.  Examples include vehicles, buildings, walls and PPE.

The physical arrangement of shields for a particular component, equipment, or system, (A shield is a housing, screen, or other material, usually conducting, that substantially reduces the effect of electric or magnetic fields on one side of the shield upon devices or circuits on the other side.) Examples are tube shields, a shielded enclosure or cabinet for a radar receiver, and the screen around a screen room.

The metal sleeving surrounding one or more of the conductors, in a wire circuit to prevent interference, interaction or current leakage.

Protective cable covering that eliminates electromagnetic & radio frequency interference.

A metal enclosure or gasket for a circuit, or a metal shield surrounding wire conductors (coaxial or triaxial cable) to lessen interference, interaction, or current leakage. The shield is usually grounded.

A metal enclosure for the circuit being measured or a metal sleeve surrounding wire conductors (coax or triax cable) to lessen interference, interaction, or current leakage. The shield is usually grounded.

Shielding consists of placing a conductive material between the source and the receiver to solve the issue of electromagnetic or radio frequency interference going in or out of the circuits.

Conductive envelope made of wires or metal foil that covers the dielectric and the centre conductor

The process of protecting a cable with a grounded metal surrounding, so electrical signals from outside the cable cannot interfere with transmission inside the cable.

The use of a particular material to shield an electronic component or circuit from the effects of external electric or magnietic fields.

The protective enclosure surrounding a transmission medium, designed to minimize electromagnetic interference ( EMI/RFI).

Protective covering that eliminates electromagnetic and radio frequency interference.

The separation and insulation of metal parts of a pipe joint by a special fitting which will not conduct electric current.

An electrically conductive physical barrier designed to reduce the detrimental interaction of electromagnetic fields upon devices or circuits. Commonly attached to cables or connector housings to protect against EMI and mechanical damage. See EMI/EMC.

A metallic covering used to prevent magnetic or electromagnetic fields from affecting an object. Technique designed to minimize internal and external interference.

a shield of lead or concrete intended as a barrier to radiation emitted in nuclear decay

the material between a radiation source and a potentially exposed person that reduces exposure.

A protective barrier, usually a dense material, which reduces the passage of radiation from radioactive materials to the surroundings.

Barrier of attenuating material used to reduce radiation exposure.

The use of absorbing material between a source of radiation and the detector or recipient. Shielding absorbs radiation and reduces the intensity of the incident radiation. It does not change the energy of the incident radiation. Shielding is chosen on the basis of its effectiveness for a given type of radiation, its cost and other physical attributes.

Reduction of radiation by interposing a shield of absorbing material between any radioactive source and a work area or radiation-sensitive device.

Material placed between the source of radioactive material and the body to reduce external exposure.

lead or tungsten foils which minimise the radiation crosstalk from exterior

Comprises the various materials within a nuclear power plant preventing radiation from escaping into the environment. Shielding can be steel, lead, concrete or water.

an electrostatic field radiates in the area surrounding most charged objects. This field can produce an ESD event or inductively charge other objects nearby and produce undesirable results. A conductive, grounded enclosure, such as a Faraday cage, that completely surrounds an object will shield the contents within from the effects of an external electrostatic field. A metallized bag or a conductive tote box are examples of shielding.

Material used to block or absorb radiation. Often placed between sources of radiation and people or the environment.

material, such as lead or concrete, used around a nuclear reactor to prevent the escape of radiation and to protect workers and equipment.

a barrier which is placed around radioactive substances which stops the radiation from passing through it.

The act or process of protecting or supplying with a protective device or screen. An example is a screen that protects against radiation.

A technique where the 1st attacker positions his body between the ball and his defender in order to maintain possession.

when a player places his body between an opponent and the ball; often preceeds an offensive maneuver during an attack.

A technique used by a ball carrier to protect the ball from a defender closely marking him.

The tactic of a ball carrier putting his body between the ball and the defender.
