Capacitive sensors are not a specific brand but a category of industrial sensors used for proximity detection, level measurement, and touch-sensitive applications. They are manufactured by various companies globally, including prominent brands like Pepperl+Fuchs (Germany), Balluff (Germany), and Omron (Japan). These sensors are widely used in industries such as manufacturing, automotive, food and beverage, and pharmaceuticals. Key products include proximity sensors, touch switches, and level sensors, which operate by detecting changes in capacitance caused by the presence or absence of a target object. Capacitive sensors are valued for their durability, non-contact operation, and ability to function in harsh environments.
