Gold-electrodes consist of a silver-electrode with a gold-alloy. Depending on the manufacturers and manufacture-procedures, this alloy might have different density or strength. The gold electrodes offered by NR Sign consist of a silver bearer-material and possess a gold-layer of 31J. Electrodes having a coating of 21J are also available. The stronger the layer, the better and longer-lived the electrode is. The shielded/unshielded cable has a length of 120cm and is equipped with a female 2mm or male 2mm pin or dipole plug.
