In 2026,Global IO-Link Size is Estimated to be USD 3636 Million

IO-Link is a short distance, bi-directional, digital, point-to-point, wired (or wireless), industrial communications networking standard (IEC 61131-9) used for connecting digital sensors and actuators to either a type of industrial fieldbus or a type of industrial Ethernet. Its objective is to provide a technological platform that enables the development and use of sensors and actuators that can produce and consume enriched sets of data that in turn can be used for economically optimizing industrial automated processes and operations.
An IO-Link system consists of an IO-Link master and one or more IO-Link devices, i.e. Sensors or Actuators. The IO-Link master provides the interface to the higher-level controller (PLC) and controls the communication with the connected IO-Link devices.
The global IO-Link size is estimated to be USD 3636 million in 2026 from USD 2313.1 million in 2020. The global IO-Link market size is expected to grow at a CAGR of 12.0% for the next five years.

In recent years, the Internet of Things technology has developed rapidly in the industrial field, and a new generation of automation products based on Ethernet technology has been widely used. IO-Link is a leading communication technology with a high price/performance ratio. With the development of industrial Internet of Things, the implementation of the Industry 4.0 project and the promotion of smart manufacturing by governments, the adoption rate of fieldbus technology is declining, and more and more production lines use industrial Ethernet-based systems.
