The IO-link market is anticipated to experience substantial growth, primarily driven by the increasing penetration of the Internet of Things (IoT). The IoT involves a network of interconnected devices, both digital and mechanical, as well as individuals, animals, or objects, each assigned unique identifiers (UIDs). These entities can communicate over a network without requiring direct human-to-human or human-to-computer interaction. IO-link facilitates real-time communication, remote configuration, and diagnostics for sensors and actuators in the context of IoT. For example, a report by IoT Analytics in May 2022 indicated an 8% increase in global IoT connections, reaching 12.2 billion active endpoints. Predictions suggest that the IoT industry will grow by 18%, reaching 14.4 billion active connections in 2022, with an estimated 27 billion linked IoT devices by 2025. This surge in IoT penetration is a key factor fueling the growth of the IO-link market.

A significant driver for the IO-link market is the expanding aerospace and defense industry. This sector encompasses the development, production, and maintenance of aerospace systems and defense equipment. IO-link technology is instrumental in enhancing connectivity, efficiency, and real-time data exchange within complex aerospace and defense systems. This technology enables seamless communication among sensors, actuators, and other devices, facilitating precise control, monitoring, and diagnostics. Notably, the aerospace and defense industry experienced substantial growth, with the Airspace Industries Association reporting a $892 billion combined sales figure in 2021, a 2.1% increase from the previous year. Additionally, exports from the sector rose by 11.2% to $100.4 billion. Consequently, the robust growth of the aerospace and defense industry is contributing significantly to the expansion of the IO-link market.

The growth of the IO-link market is further propelled by the increasing penetration of Industry 4.0. Industry 4 refers to smart and connected production systems designed for real-time decision-making by interacting with the physical world. IO-link plays a crucial role in extending Industry 4 solutions to even the smallest inductive sensors by connecting them to industrial Ethernet. According to Conexus Indiana, a non-profit organization, 58% of companies successfully implemented or piloted an Industry 4 technology in 2022, a notable increase from 43% in 2021 and 21% in 2020. Therefore, the rising adoption of Industry 4 technologies is a key factor driving the growth of the IO-link market.

The IO-link market is witnessing a notable trend marked by the increased adoption of next-generation technologies. Major players in the market are directing their efforts towards the development of advanced technologies such as IoT, industrial robotics, and cloud technologies as part of their strategy to maintain a competitive edge. For example, in January 2022, ASIX Electronics Corporation, a Taiwan-based IC design company specializing in network connectivity, Ethernet, and USB solutions, introduced the AX58400 EtherCAT to IO-link gateway solution. This gateway utilizes a combination of EtherCAT industrial Ethernet fieldbus technology and IO-Link intelligent communication technology, supporting up to 8 IO-link devices, including smart sensors and actuators. It facilitates the parameterization and diagnostics of IO-Link devices via EtherCAT, simplifying the configuration and monitoring of IO-link devices.

Leading companies in the IO-link market are intensifying their focus on creating innovative products, such as the G3 IO-Link Master, to offer customers a cost-effective solution for smart and analog sensor connectivity. A Class A IO-Link master, in this context, refers to a port class establishing a point-to-point connection between an IO-Link master and an IO-Link device (sensor or actuator) using an unshielded three-core cable. In August 2023, Emerson Electric Co., a prominent US-based manufacturing company, launched a new Class A IO-Link master, the G3 IO-Link Master. This product is well-suited for machine architectures featuring numerous sensors and pneumatic valves, emphasizing the importance of reliable digital data communication between field devices, such as sensors, and the machine controller. The commitment to developing cutting-edge solutions underscores the ongoing emphasis on next-generation technologies within the IO-link market.
