PMP markers are very simple to use: the appropriate characters are collected in order on the insertion tool then pushed into the transparent holder mounted on the cable. Once inserted, the characters are protected from degradation by water, alcohol, acids, alkalis and numerous solvents. Characters are available printed in black on white or yellow backgrounds, or colour coded according IEC Standard 757. PM transparent marker holders can be premounted on cables for later insertion of marking characters without affecting the wiring. PM transparent holders, in seven range taking sizes, for identifying cables from 0,10 to 240 mm2. PM-ET self adhesive transparent holders for identifying components and equipment.
