IO-Link is a standardized communication protocol used in industrial automation, and the 'Photoelectric sensors O11 miniature type' refers to a specific category of sensors compatible with this protocol. These sensors are typically produced by various manufacturers specializing in industrial automation components. For instance, companies like Balluff (Germany), Sick AG (Germany), or Pepperl+Fuchs (Germany) are known for producing high-quality IO-Link-enabled photoelectric sensors. These sensors are widely used in manufacturing, packaging, and material handling industries for object detection, positioning, and quality control. The O11 miniature type is compact, making it suitable for space-constrained applications while maintaining high precision and reliability.
