Protective films are available for almost all SIMATIC HMI devices. They protect the display from dirt and scratching during operation and in harsh environments. The SIMATIC protective films are non-reflective. This ensures that the display is always easy to read, even when using protective films.
The protective film can be removed without leaving any adhesive residue on the front. Adhesive-edged protective films are now available for resistive touch systems (membrane touch).
For multi-touch systems (typically with glass fronts), full-width adhesive protective films are available. Full-width adhesive films should not be used on single-touch systems, as the touch system could be damaged when removing the film. All full-width adhesive films can be trimmed to any size, this does not affect the quality of the film. Adhesive-edged films should not be trimmed, as this would lead to the loss of the adhesive edge.
