Industrial automation plays an increasingly important role in today’s global economy. Not only does it improve production efficiency and reduce costs, but it also ensures product quality and consistency. Industry 4.0 has further accelerated the rapid development of industrial automation, robotics, and unmanned systems. These automated devices and their associated sensors typically need to operate in harsh environmental conditions and must be corrosion-resistant, shock-resistant, dustproof, moisture-resistant, and immune to interference.
