The growth in the forecast period can be attributed to rising deployment of digital factories, adoption of smart packaging automation, expansion of intralogistics automation, growing need for real-time device-level communication, increasing demand for intelligent sensor networks. Major trends in the forecast period include expansion of industry 4.0-enabled io-link networks, growth of IoT-based sensor interoperability, adoption of cloud-integrated io-link diagnostics, integration of AI-driven predictive maintenance, advancement of robotics-oriented io-link automation.

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, in January 2023, the World Economic Forum, a Switzerland-based non-profit organization, estimated that the number of connected IoT devices would reach 30 billion by 2025. This surge in IoT penetration is a key factor fueling the growth of the IO-link market.

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.

In August 2023, ifm group, a Germany-based industrial automation technology company, acquired Sentinum GmbH for an undisclosed amount. Through this acquisition, ifm group aims to enhance its IoT and wireless sensor portfolio by incorporating Sentinum’s expertise in radar and radio sensor technologies for smart city and smart building applications. Sentinum GmbH is a Germany-based manufacturer providing IO-Link solutions.
