General
Colour	Black

The EV-permanent black is a marking pen from the brand Ses-Sterling, specifically developed for labelling marking fields on SES-MARKERS marking cards. It is a permanent marker with a fibre tip, suitable for durable and clearly legible markings in electrical and IT installation technology. The marker's colour is black, ensuring good readability on light or neutral backgrounds. The medium tip allows for precise application, with line width sufficient for most marking tasks.

Marking pen
This item is designed as a fibre pen, enabling even ink distribution and clean line formation. The fibre tip is designed for continuous and smooth writing, allowing longer texts to be written without interruption. Use as a permanent marker means the ink is not removable after drying and is resistant to mechanical stress and minor environmental influences.

Applications
The EV-permanent black is primarily intended for labelling marking fields on SES-MARKERS marking cards. These cards are commonly used in electrical and IT installation to uniquely identify cables, lines, devices, or connections. Marking is done directly on the designated fields of the cards, with the black ink providing clear visibility on the typically light or white surfaces.

Functions and equipment in detail
The marker features a medium tip, designed for universal use in installation technology. The fibre tip ensures even ink delivery, preventing ink gaps or uneven lines even during longer labelling tasks. The black ink is designed for permanent markings that are not removable and do not easily discolour. The marker is used manually, without additional tools or power supply.

Technology explained simply
A fibre pen uses a fibre structure at the tip to absorb ink from inside the pen and transfer it evenly to the surface. Unlike ballpoint pens or pens with metal tips, the fibre enables a softer and smoother writing experience. The ink is permanent, meaning it is chemically fixed after drying and cannot be removed by mechanical friction or slight moisture. This is particularly important in installation technology, where markings must remain visible over long periods.

Compatibility and accessories
The EV-permanent black is specifically developed for labelling SES-MARKERS marking cards. These cards are part of a marking system used in electrical and IT installation for the unique identification of lines, cables, and devices. The combination of marker and marking card enables structured and clear labelling.

Mounting and installation
Mounting or installation of the marker does not refer to mechanical fastening, but to its application: the pen is used manually to label marking fields. No tools or accessories are required. Application is direct onto the surface of the marking card, with the ink drying and adhering permanently after application.

Advantages in operation
Using the EV-permanent black provides clear and durable labelling, ensuring identification of installation components. The black ink offers good readability, especially on light backgrounds. The fibre tip enables precise and smooth writing, allowing longer texts to be labelled without interruption. The permanent ink ensures the marking remains legible over time, which is important for maintenance and documentation of installations. The marker is used without additional tools, making application simple and quick.
