"Magusign" is an energy-saving magnetic reversal display that flips a permanent magnet disk (display panel) using instantaneous pulse electric current. It consumes no power except during the reversal operation, and the disk maintains its position due to residual magnetism. The disk operates solely through magnetic reversal, ensuring extremely high reliability and can be used semi-permanently. The color surface of the disk uses fluorescent colors, making it clear and easy to see, allowing for information categorization by color. [Features] - Energy-efficient and self-holding - Long lifespan - Excellent visibility For more details, please contact us or download the catalog.
