The product Pliograph+ 2.8 Z white from Ses-Sterling is a marking ring booklet for the clear identification of cables, lines, and other installation components in the field of electrical and IT technology. It is a system of PVC marking rings with a width of 2.8 mm, manufactured in white color and featuring a black, permanent print with the letter Z. These markings serve visual differentiation and documentation during installations, maintenance work, or servicing of technical systems. The rings are designed for use in industrial and commercial electrical engineering as well as in building automation.

Applications
The marking rings of type Pliograph+ 2.8 Z white are particularly suitable for marking cables, lines, switches, connectors, and other electrical or IT components. They are frequently used in building installations, industrial technology, network cabling, or automation technology, where clear and durable marking is required. The letter Z serves as a unique identifier, which can represent a specific function, connection, or category depending on internal systems or project planning. The use in combination with other marking rings featuring different letters or numbers enables a structured and clear labeling of complex systems.

Functions and Equipment in Detail
The product consists of a booklet containing 150 identical marking rings. Each ring is made of PVC, ensuring high mechanical stability and resistance to environmental influences such as moisture or minor temperature fluctuations. The white color provides good readability of the black print Z, ensuring the marking remains clearly visible even under low lighting or near other colors. The rings are dimensioned to be easily slipped onto cables with a diameter of up to approximately 10 mm, with exact fit varying depending on cable diameter. Installation is done by simply sliding the rings onto the cable, where they elastically adapt and ensure a secure fit.

Technology Explained Simply
The marking rings are made of a flexible yet durable PVC material that can be easily stretched to slide onto the cable and then holds a stable position. The width of 2.8 mm provides sufficient surface area to clearly display the print Z. The black print is permanent and not washable, ensuring the marking remains intact even after prolonged use or contact with slightly soiled surfaces. The material choice ensures good resistance to mechanical stress, such as during installation or maintenance. The rings are not self-adhesive but are secured by mechanical fit.

Compatibility and Accessories
The marking rings of type Pliograph+ 2.8 Z white are part of the Pliograph+ system from Ses-Sterling and can be combined with other rings from the same product series to create a consistent marking system. Use in combination with rings of different colors or with other letter and number combinations enables detailed and structured labeling. The rings are designed for use with standard cables and lines commonly used in electrical and IT installations. No specific additional tools or devices are required for use — the rings are manually slid onto the cable.

Installation and Mounting
Installation is done by simply sliding the rings onto the cable. It is important to ensure the cable diameter is within the ring’s stretch range to guarantee a secure fit. The rings are not self-adhesive but hold in place through elastic tension on the cable. Positioning should be done where the marking is clearly visible and identifiable, for example, at connection points, branch points, or the start of a line. Installation requires no special tools or accessories.

Advantages in Operation
The use of marking rings provides a clear, durable, and cost-efficient way to uniquely identify cables and lines. The white color with black print Z ensures high readability, even in complex installations. PVC construction guarantees long service life and resistance to mechanical stress. The booklet packaging with 150 rings enables efficient storage and distribution, simplifying planning and execution of installations or maintenance work. The rings are easy to handle and require no additional tools or mounting aids.
