EMI (Electromagnetic Interference) / RFI (Radio Frequency Interference) is an unwanted disturbance that affects an electrical circuit due to either electromagnetic conduction or electromagnetic radiation emitted from an external source. The disturbance may interrupt, obstruct, or otherwise limit the effective performance of the circuit.

The Standard version has an integral O-Ring, which presses the braiding against the inside wall of the body but can only be used with BRAIDED shield.
