As per the Analyst at MRFR, 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.

IO Link Market Opportunity
INCREASING ADOPTION OF IO-LINK IN AUTOMOTIVE INDUSTRY
IO-Link is a widely adopted communication technology in the automotive industry. It is a standardized, bi-directional communication interface that enables the exchange of data between devices in a vehicle or on the production line. IO-Link is used for a variety of applications, including diagnostics, monitoring, and control of various systems in a vehicle.
Small shutdowns can result in significant losses in the manufacturing sector in the automotive industry. A mistake can ruin the entire production process. IO-Link equipment eliminates such downtime, improves product and process efficiencies, and ensures regular preventative maintenance. IO-Link masters are designed according to AIDA specifications for vehicle performance and provide improved performance.
The German Domestic Automotive Manufacturers (AIDA) Automation Initiative (AIDA) has defined a standard for IO-Link masters in the automotive industry. All field modules are provided with L-coded electrical connections to be used with active ground. Vertical integration in automation for the automotive industry includes support for EtherCAT and EtherNet/IP. In addition, IO-Link products are used for seamless integration with controllers. Thus, the automotive industry is anticipated to offer huge opportunities for the IO-Link ecosystem players in the near future.
