EKF PROxima plastic elastic cable markers have indelible alphanumeric markings on the surface. They are placed on cables and wires to assign a designation to the conductor. For example, to mark a wire according to a compiled circuit diagram, so that the section of the compiled circuit and the purpose of the conductor can always be identified in the future. Using combinations of letters and numbers, cable markers can assign any designations convenient for you to the conductors.
