IO-Link - Capacitive sensors in cylindrical housing refers to a range of industrial sensors designed for precise object detection, commonly used in automation and manufacturing. These sensors are typically produced by leading industrial automation companies, such as Balluff (Germany), Pepperl+Fuchs (Germany), or IFM (Germany), which specialize in IO-Link-enabled devices. The capacitive sensors in cylindrical housings are widely used in industries like automotive, packaging, and material handling for non-contact detection of liquids, powders, and solid objects. Their robust design and IO-Link compatibility enable seamless integration into Industry 4.0 systems for real-time data communication and diagnostics.
