On April 14, 2026, the SensorShenzhen 2026 exhibition opened, and domestically produced digital interface kits became the focus of technical sourcing by distributors in Germany, Italy, and other countries. The exhibition’s impact spans industrial automation, smart sensor integration, OEM equipment manufacturing, and cross-border supply chain services, among other fields. Because it reflects how modular interface solutions are accelerating their entry into Europe’s midstream supply chain system, it is worth close attention from relevant companies.

Event Overview

From April 14–16, 2026, the SensorShenzhen exhibition was held, reaching 32 cross-border cooperation intentions; more than 60% of them focused on “domestic digital interface kits”——a type of plug-and-play module compatible with multiple protocols including IO-Link, AS-i, HART-IP, and Modbus-TCP. On-site feedback shows that distributors in Germany and Italy are evaluating this solution in batches as a replacement for traditional PLC gateways in order to shorten production line integration cycles. For Chinese export enterprises, this solution supports rapid access to the European OEM supply chain through modular interfaces without requiring complete machine certification.

Which Market Segments Will Be Affected

Direct Trading Enterprises

Reason for impact: Such enterprises usually undertake the export of interface products to overseas distributors. In this exhibition, more than 60% of cooperation intentions were concentrated on digital interface kits, indicating that they are shifting from auxiliary accessories to the role of key middleware.
Impact: The order structure may shift from scattered trial orders to bulk technical onboarding procurement; the certification pathway may shift from complete machine CE/UKCA to module-level Declarations of Conformity （DoC） as the main route, bringing changes to delivery cycles and compliance costs.

Processing and Manufacturing Enterprises

Reason for impact: As ODM/OEM manufacturers of such kits, they need to adapt to multi-protocol consistency testing and rapid model switching capabilities.
Impact: Production lines need to strengthen protocol stack validation capabilities （such as IO-Link Device Stack certification） and improve flexible manufacturing capabilities for small-batch, multi-configuration production; some manufacturers may face joint interoperability testing requirements from distributors.

Channel Distribution Enterprises

Reason for impact: Distributors in Germany and Italy are incorporating such kits into standard selection lists for replacing traditional PLC gateways.
Impact: The channel value focus is shifting from simple logistics delivery to technical parameter matching, protocol compatibility pre-validation, and localized application support; some enterprises need to supplement their protocol debugging toolchain and basic training capabilities.

Supply Chain Service Enterprises

Reason for impact: Modular interface solutions reduce dependence on complete machine certification, but raise requirements for process control in areas such as protocol consistency, EMC immunity, and firmware traceability.
Impact: Demand is rising for services such as third-party testing, technical documentation review, and firmware version management; specialized service capabilities for standards such as IEC 61131-9 （IO-Link） and IEC 62026-2 （AS-i） are becoming differentiated support points.

What Key Points Should Relevant Companies or Practitioners Pay Attention To, and How Should They Respond at Present

Pay Attention to Subsequent Updates to EU Harmonized Standards

What is currently more worthy of attention is: EN IEC 61131-9:2023 has incorporated IO-Link v1.1.3 consistency requirements, while the supporting test specifications for HART-IP and Modbus-TCP in IEC 61784-2 are under revision. Companies should track draft notices published on the CENELEC official website to avoid the need for re-validation of delivered modules caused by standard iterations.

Differentiate Market Access Pathways in Key Markets

Analysis shows: German distributors generally accept module market access based on the manufacturer’s self-declaration （DoC）, but some OEM customers in Italy still tend to require protocol interoperability reports issued by third-party institutions （such as IO-Link Device Test Reports issued by TÜV Rheinland or SGS）. Companies need to prepare compliance delivery packages by country according to the location of target customers.

Sort Out the Existing Product Protocol Stack Support List in Advance

From an industry perspective: not all kits labeled “multi-protocol compatible” have passed full protocol stack consistency testing. Companies should verify whether their products have verifiable information such as IO-Link Device Class A/B certification, AS-i Profile 2.1/3.0 registration numbers, HART-IP Device Description （DD） file numbers, and Modbus-TCP Object Dictionary （OD） mapping tables, and archive the corresponding test report numbers.

Assess Joint Technical Response Capabilities with Distributors in Advance

Observation shows: on-site feedback indicates that purchasing decisions by German and Italian distributors rely not only on datasheets, but also more on whether production line-level rapid deployment support can be provided （such as preset configuration files, diagnostic tool SDKs, and interfacing cases for common PLC masters）. Companies should prepare reference design documents for typical application scenarios and lightweight debugging tools in advance, rather than only providing hardware modules.

Editor’s Viewpoint / Industry Observation

Analysis shows：the procurement interest presented at this exhibition currently looks more like a structural signal——namely, that Europe’s midstream channels are actively driving the downward extension of interface-layer standardization to alleviate the problems of protocol fragmentation and integration delays faced by OEM manufacturers in Industry 4.0 upgrades. It has not yet formed large-scale shipment results, but it has clearly pointed to the starting point for implementing a new division-of-labor logic of “module as interface.” What the industry needs to continue watching is: within the next 6–12 months, whether the first European OEM equipment model based on such kits will complete CE certification and enter mass production; and whether discussions will be launched at the IEC/ISO level on a unified conformity framework for multi-protocol interface modules.

Conclusion:
The core industry significance of this information lies in the fact that domestically produced digital interface kits are shifting from an “optional item” to one of the “functional must-have items” in Europe’s automation supply chain. At present, it is more appropriate to understand this as an early signal before the tipping point of technology adoption, rather than as a mature market landscape. Relevant companies should take protocol compatibility validation capabilities as the anchor point and rationally assess their preparedness in three areas: module-level compliance, rapid response, and technical coordination, so as to avoid equating exhibition popularity with immediate commercial conversion.
