IO-Link is a communication standard widely used in industrial automation, not a specific brand. The 'Photoelectric sensors O24 miniature type' refers to compact photoelectric sensors compatible with IO-Link, often produced by manufacturers like Balluff (Germany), SICK (Germany), or IFM (Germany). These sensors are used in industries such as manufacturing, packaging, and logistics for object detection, positioning, and quality control. The O24 series typically offers high precision in a small form factor, suitable for space-constrained applications.
