IO-Link is a standardized communication protocol (IEC 61131-9) used in industrial automation, enabling smart sensors and actuators to connect with control systems. The 'Photoelectric sensors O25 miniature type' refers to compact photoelectric sensors compatible with IO-Link, typically used for object detection in manufacturing and logistics. These sensors are produced by various global brands, such as ifm (Germany), Balluff (Germany), or Sick AG (Germany), known for their high precision and durability. They serve industries like automotive, packaging, and material handling, offering features like easy integration, real-time diagnostics, and adjustable parameters via IO-Link.
