Needle contact with the NK contacts are made on paper and plastic insulated wires with wire diameters from 0.35 to 1.4 mm for test and measurement purposes. The NK is also known as bridging cord to verwenden.Der Test cord NK can to paper and plastic insulated wires used with a conductor diameter of 0.35 to 1.4 mm werden.Zur performing measurements of NK is clamped to the wire to be tested and the respective test or measuring instrument, such as PTS 93i or KAPG 80 (90), is connected. The fine gold tip penetrates the insulation and makes contact with the conductor. Here are no Meßwertveränderungen feststellbar.Nach disconnecting the Nadelkontaktierers are no measures for the recovery of the core insulation erforderlich.Mittels a commercial plug coupling two Test cord can be connected so that the needle contact can be used as a bridge line for interruption-free changeover work.
