Ultrasonic sensors are essential devices in automation and industrial applications, known for their ability to detect objects, measure distances, and monitor levels without physical contact. They operate by emitting high-frequency sound waves and analyzing the reflected signals, providing accurate and reliable data. Common products in this category include proximity sensors, distance measurement sensors, and liquid level sensors. These sensors are widely used in robotics, conveyor systems, and warehouse automation due to their durability, high precision, and resistance to environmental interference. Key features often include adjustable detection ranges, compact designs, and compatibility with various industrial interfaces like IO-Link or analog outputs.
