The demand for IO-links is being influenced by the growth of the Industrial Internet of Things (IIoT). An average factory present anywhere in the world is aged around 25 years, and it relies on disconnected machines that are around 9 years old. Globally, around 77% of all organisations have limited resources and technological know-how to track their excessive power consumption patterns. As per the American Society for Quality, the digitisation of processes by manufacturing companies has led to an 82% improvement in overall efficiency and 45% in customer satisfaction. There has also been a 49% reduction in product defects. This is expected to prompt an increasing number of producers to switch towards digitally advanced factories, thereby increasing the IO-link market value in the upcoming years.
Frontier connectivity ensures reliable, low-latency, and wireless communication between assembly lines across different manufacturing plants, which can add a value of USD 200 billion to the global manufacturing industry by reducing defects and preventing breakdowns and rework. Moreover, the introduction of next-generation autonomously guided vehicles, which can make sophisticated coordination and navigation decisions in real-time, is expected to drive the rate of IO-link market development. This can have a potential economic impact worth USD 130-USD 200 billion on global GDP.
Establishment of smart factories; rising reliance on digital twins; the emergence of 5G; and the growing need for extra device intelligence are the major factors favouring the IO-link market growth
By the end of 2024, major power, energy, and utility companies are expected to convert 43% of their production centres into smart factories. This is expected to favourably impact the IO-link market dynamics.
In 2020, 24% of enterprises were using digital twin technology, with 42% expected to adopt it in the upcoming years. This can help them in reducing operational inefficiencies while deriving accurate insights.
By 2030, the global manufacturing sector can potentially generate an additional GDP impact of USD 400 billion to USD 650 billion by relying on 5G networks for enabling critical industrial communication, including wireless control of machines. This can accelerate the rate of the IO-link market development.
IO-Link devices have built-in intelligence features, which enable the performance of advanced functions. For instance, sensors equipped with IO-link predict maintenance needs, perform self-diagnostics, and provide a detailed error report. This facilitates improved decision-making.
Smart manufacturing technologies have significantly impacted production-defined industries. As per the market analysis, global enterprises invest 3.24% of their revenue towards building 40% additional smart factories during 2020-2023. This is nearly 1.7 times higher than the investment made during 2016-2019, indicating the numerous possibilities for the IO-link market expansion. Moreover, machine-to-machine connections supporting IoT applications support over 50% of the world’s connected devices (28.5 billion), due to which IO-links are expected to become increasingly important.
