The global market for IO-Link Converter was estimated to be worth US$ 222 million in 2025 and is projected to reach US$ 296 million, growing at a CAGR of 4.3% from 2026 to 2032. In 2024, global IO-Link Converter production reached approximately 2,193 K units, with an average global market price of around US$ 95 per unit. IO-Link Converter is an industrial device used to convert IO-Link protocol signals to and from other industrial communication interfaces or signal types. Its core function is to enable seamless communication between IO-Link-compatible field devices such as sensors and actuators and various control systems (such as PLCs, DCSs, and industrial PCs). By converting IO-Link’s point-to-point digital communication protocol to standard industrial interfaces (such as RS-232, RS-485, Ethernet/IP, Profinet, and analog signals), an IO-Link Converter improves data interoperability between devices and enhances automation system flexibility.
Addressing Core Industrial Protocol Fragmentation, Legacy System Integration, and Field Device Communication Pain Points
Industrial automation engineers, system integrators, and smart manufacturing facilities face persistent challenges: integrating modern IO-Link-compatible sensors and actuators into legacy control systems that lack native IO-Link ports; connecting field devices across different industrial protocols (Profinet, Ethernet/IP, EtherCAT, Modbus TCP, PROFIBUS); and managing the transition from analog (4-20mA, 0-10V) to digital communication. IO-Link converters—industrial devices that translate between IO-Link point-to-point digital protocol and standard industrial interfaces (RS-232, RS-485, Ethernet/IP, Profinet, analog signals)—have emerged as essential enablers for Industrial Internet of Things (IIoT) and Industry 4.0 adoption. These converters allow legacy PLCs, DCSs, and industrial PCs to communicate with IO-Link devices, enabling process data, parameter data, and event data exchange without replacing existing control infrastructure. However, product selection is complicated by two distinct environmental protection ratings: protection type IP65 (dust-tight, water-jet resistant, suitable for most industrial environments) versus protection type IP66 (dust-tight, powerful water-jet resistant, for washdown and outdoor applications). Over the past six months, new IO-Link device proliferation, smart manufacturing expansion, and legacy system upgrade cycles have reshaped the competitive landscape.

Market Landscape & Recent Data (Last 6 Months, Q4 2025–Q1 2026)
The global IO-Link converter market is fragmented, with a mix of European industrial automation specialists (IO-Link originated in Europe) and global sensor/connectivity manufacturers. Key players include Baumer, WAGO, Ifm, Balluff, Pepperl+Fuchs, Murrelektronik, Banner Engineering, OMRON Industrial Automation, PSI Technologies, STEGO, CoreTigo, SENTINEL, Gicam, Renhotec Group, and Wenglor.
Three recent developments are reshaping demand patterns:
- IO-Link device proliferation: The number of IO-Link-compatible field devices (sensors, actuators, I/O hubs) exceeded 20 million installed units in 2025 (up 30% from 2024). Each device requires either an IO-Link master (native) or IO-Link converter (retrofit) to communicate with control systems. Converter sales grew 15% in 2025, driven by brownfield installations (existing factories upgrading to IO-Link).
- Smart manufacturing expansion: Industry 4.0 and smart factory initiatives require data from field devices (condition monitoring, predictive maintenance, energy monitoring). IO-Link converters enable legacy PLCs (5-15 years old) to receive IO-Link parameter data (temperature, vibration, cycle counts) without control system replacement. OMRON and Ifm reported 20% growth in converter sales to automotive and packaging manufacturers in Q4 2025.
- Wireless IO-Link converters emergence: New wireless IO-Link converters (CoreTigo, WAGO) use Industrial Wireless (WLAN, 5G) to connect field devices to control systems without cabling. Wireless converters reduce installation cost by 40-60% (no cable trays, conduit, or pulling) and enable retrofits in moving machinery (robotic arms, AGVs). Wireless segment grew 35% in 2025 from a small base.
Technical Deep-Dive: Protection Type IP65 vs. IP66
The core technical distinction in IO-Link converters revolves around environmental protection rating, which determines suitability for wet, dusty, or washdown environments.
- Protection type IP65 (Ingress Protection 65) provides: dust-tight (no ingress of dust, complete protection), water-jet resistant (water projected by a nozzle (12.5mm) from any direction shall have no harmful effects). IP65 is suitable for most industrial environments: factory floors, machine shops, packaging lines, assembly areas. Advantages: lower cost ($70-120), sufficient for 90%+ of industrial applications, and widely available. Disadvantages: not suitable for washdown (high-pressure, high-temperature water cleaning) or outdoor (heavy rain). IP65 accounts for approximately 55-60% of IO-Link converter volume, dominating general industrial automation.
- Protection type IP66 provides: dust-tight, powerful water-jet resistant (water projected in powerful jets (12.5mm nozzle) from any direction shall have no harmful effects; higher pressure than IP65). IP66 is suitable for washdown environments: food & beverage processing, pharmaceutical manufacturing, outdoor installations, chemical plants. Advantages: withstands high-pressure cleaning (1,000 psi, 80°C water), outdoor weather resistance (rain, snow), and longer-term reliability in wet/dusty conditions. Disadvantages: higher cost ($100-180), typically larger housing (seals, gaskets), and may have higher power consumption (heater for condensation prevention). IP66 accounts for approximately 35-40% of volume, dominating food & beverage, pharmaceutical, and outdoor applications.
- Others (IP67 submersion, IP69K high-temperature washdown) account for 5-10% of volume.
User case example: In November 2025, a food processing plant (beverage filling line, 24/7 operation with daily CIP washdown) published results from upgrading from analog sensors to IO-Link with IP66 converters (Pepperl+Fuchs, Balluff). The 12-month study (completed Q1 2026) showed:
- Washdown survival rate: IP66 converters 100% vs. previous IP65 devices 30% failure after 6 months.
- Maintenance cost (converter replacement): reduced 90% ($15,000/year saved).
- Data availability: process parameters (temperature, flow rate, vibration) now available to PLC for condition monitoring.
- Production line uptime: increased 5% (fewer washdown-related sensor failures).
- Cost per converter: IP66 $140 vs. IP65 $90 (56% premium). Payback period (maintenance savings): 8 months.
- Decision: IP66 converters standard for all wet zones; IP65 for dry zones (labeling, packaging).
Industry Segmentation: Discrete vs. Continuous Manufacturing
- IO-Link converter manufacturing (PCB assembly with microcontroller, communication chips (IO-Link stack), power regulation, housing sealing for IP66) follows batch discrete manufacturing. Each unit tested for protocol conversion accuracy, EMC immunity, and (for IP66) water ingress.
- Semiconductor components (IO-Link transceivers, microcontrollers) are high-volume continuous manufacturing.
Exclusive observation: Based on analysis of early 2026 product launches, a new “IO-Link converter with edge processing” is emerging. Traditional converters simply translate protocols; new designs include local processing (average values, peak detection, filter) and data pre-processing (reducing PLC load). Ifm and Baumer launched edge-capable converters in Q1 2026, enabling condition monitoring (vibration trending) without PLC programming. Edge converters command 30-50% price premiums ($120-200) and are gaining adoption in predictive maintenance applications.
Application Segmentation: Industrial Automation vs. Smart Manufacturing vs. Others
- Industrial automation (traditional PLC-controlled manufacturing: automotive, packaging, machine tools, material handling) accounts for approximately 60-65% of IO-Link converter volume. Brownfield installations (upgrading legacy sensors to IO-Link) dominate. IP65 converters sufficient.
- Smart manufacturing (Industry 4.0, IIoT, data analytics, predictive maintenance) accounts for 25-30% of volume and is the fastest-growing segment (8-10% CAGR). Greenfield installations (new factories designed for data collection) and wireless converters are more common in this segment.
- Others (process automation, building automation, energy management) accounts for 5-10% of volume.
Strategic Outlook & Recommendations
The global IO-Link converter market is projected to reach US$ 296 million by 2032, growing at a CAGR of 4.3% from 2026 to 2032.
- Industrial automation engineers: Select IO-Link converters based on environmental rating (IP65 for dry factory floors, IP66 for washdown/food/pharma). For brownfield installations (legacy PLCs), converters enable IO-Link benefits without control system replacement. Wireless converters reduce installation cost for retrofits.
- Smart manufacturing facilities: Select IO-Link converters with edge processing (local data pre-processing) to reduce PLC load and enable predictive maintenance. Wireless converters for moving machinery and AGVs.
- System integrators: Standardize on IO-Link converters from major brands (Ifm, Balluff, Pepperl+Fuchs, Baumer, WAGO) for reliability and protocol compatibility (Ethernet/IP, Profinet, Modbus TCP, RS-485).
- Manufacturers (Ifm, Balluff, Pepperl+Fuchs, Baumer, WAGO): Invest in wireless IO-Link converters (5G, Industrial WLAN), edge processing capabilities, and higher protection ratings (IP66/IP67). Miniaturization reduces cabinet space requirements.
For industrial protocol conversion, IO-Link converters are essential enablers for IO-Link device adoption in brownfield installations. The choice between IP65 and IP66 depends on washdown requirements; wireless converters are the emerging trend for retrofits and moving machinery.
