Industry 4.0 continues to propel the development of smart factories through the unobstructed integration of industrial automation, IIoT, and data exchange. One key advancement in such a shift is the widespread use of IO-Link Wireless, officially standardized under IEC 61139-3 in 2024. Such a standard guarantees high reliability (packet error rate <10⁻⁹), ultra-low latency (≤5 ms), deterministic communication, and scalability, overcoming the drawbacks of conventional wired and wireless solutions in aggressive industrial applications. In contrast to traditional wireless technologies like Wi-Fi and Bluetooth, which are plagued by industrial interference, IO-Link Wireless offers real-time, vendor-independent connectivity without the expense and maintenance concerns of cabling. The system can handle up to 40 devices per master, facilitating seamless data exchange on rotating machinery, conveyor systems, robotics (EOAT), and predictive maintenance applications.

Recent developments in industry highlight their increasing popularity. In February 2025, SICK introduced its IO-Link Wireless Gateway, simplifying installation and allowing real-time streaming of sensor data for improved process automation. Likewise, Balluff, Siemens, and Pepperl+Fuchs have broadened their IO-Link Wireless offerings, focusing on cost-saving retrofits, flexible system expansion, and plug-and-play integration with existing wired IO-Link infrastructures. Further, the incorporation of System-on-Module (SoM) and System-on-Chip (SoC) solutions with 2.4 GHz transceivers has drastically lowered the footprint and price of IO-Link Wireless devices, expediting their penetration across industries. With Industry 4.0 calling for ultra-reliable, scalable, and interference-resistant industrial wireless connectivity, IO-Link Wireless has emerged as a vital enabler of next-generation smart factories, ensuring smooth communication within industrial ecosystems while maximizing efficiency, uptime, and cost-effectiveness.

Segmental Analysis

The Global IO Link Market has been segmented based on Type, by Component, by Industry, by Application.

Based on Type, this segment includes IO-Link Wired and IO-Link Wireless. The IO-Link Wired segment dominated the global market in 2024, while the IO-Link Devices segment is projected to be the fastest–growing segment during the forecast period. IO-Link Wired is a standardized communication protocol (IEC 61131-9) that is used in industrial automation to connect sensors and actuators to controllers. It employs a point-to-point connection with ordinary three-wire connections, making it simpler to configure than other fieldbus systems. IO-Link Wired is a dependable and effective way to connect sensors and actuators in industrial automation applications.

Based on Component, this segment includes IO-Link Masters (PROFINET, EtherNeVIP, Modbus-TCP, EtherCAT, Multiprotocol, Others), IO-Link Devices (Sensor Nodes (Position Sensors, Temperature Sensors, Pressure Sensors, Vibration Sensors, Others), Modules, Actuators, RFID Read Heads and Others). The IO-Link Masters segment dominated the global market in 2024, while the IO-Link Devices segment is projected to be the fastest–growing segment during the forecast period. IO-Link masters facilitate reliable, efficient communication between management and sensor/actuator levels as they assume a gateway function between Ethernet and IO Link. Up to eight IO Link devices may be directly connected—four channels are available for sensors, four channels for actuators. The growth can be attributed to their increasing usage as gateway in field applications for connecting to eight 10 link devices including valves, binary output, sensors, input modules. Furthermore, several versions of 10 link master offer ports as supply auxiliary energy for connecting actuators of 10 link and the B ports. The benefits of efficient functioning and high-quality performance will also drive the preference for IO link master.

Based on Industry, this segment includes Process Industries (Oil & Gas, Chemicals, Energy & Power), Discrete Industries (Automotive, Aerospace & Defense, Semiconductors & Electronics, Machine Manufacturing, Packaging), Hybrid Industries (Pharmaceuticals, Metals & Mining, Food & Beverages, Cement and Glass). The Discrete Industries segment dominated the global market in 2024, while the Hybrid Industries segment is projected to be the fastest–growing segment during the forecast period. Discrete manufacturing is an industry term for the manufacturing of finished products that are distinct items capable of being easily counted, touched or seen. The discrete industries segmented into automotive, aerospace & defense, machine manufacturing, packaging, semiconductor & electronics.

Based on Application, this segment includes Machine Tools, Handling and Assembly Automation Systems, Intralogistics Solutions, Packaging Automation Solutions. The Machine Tools segment dominated the global market in 2024, while the Intralogistics Solutions segment is projected to be the fastest–growing segment during the forecast period. Machine tools use various sensors that monitor pressure, level, and temperature. IO-Link-capable sensors are identified by their vendor and device ID. The user-defined program in a controller recognizes the connected sensor, validates it, and sets the sensor parameters using the parameter record. Sensors from various manufacturers can be used on the factory floor. IO-Link can also be utilized with ordinary sensors installed on a machine. Signals from these sensors are gathered, used in IO-Link sensor hubs, and transmitted to the controller.
