Industrial Ethernet Switch Market Demand Expands with Smart Manufacturing and Industrial IoT

Industrial Ethernet Becomes a Core Infrastructure for Modern Industrial Networks

As manufacturing industries continue to accelerate digital transformation, Industrial Ethernet is becoming an increasingly important networking infrastructure for factories, production lines, transportation systems, energy facilities, and industrial automation applications.

According to HMS Networks' 2026 industrial network analysis, Industrial Ethernet accounted for 79% of newly installed industrial network nodes worldwide, increasing from 76% in 2025. The continued migration from traditional fieldbus technologies toward Ethernet-based industrial communication is creating sustained demand for reliable, rugged and high-performance Industrial Ethernet switches.

At the same time, a 2026 market analysis estimates the global Industrial Ethernet Switch market at approximately USD 3.8 billion in 2026, with the market projected to reach approximately USD 6 billion by 2031. The analysis identifies smart manufacturing, deterministic networking, edge computing, cybersecurity and the migration from legacy fieldbus systems as major demand drivers.

Growing Demand for Industrial-Grade Network Infrastructure

Unlike conventional commercial Ethernet switches, industrial networking equipment must operate reliably in demanding environments. Manufacturing facilities may experience vibration, electrical interference, temperature fluctuations, dust, humidity and unstable power conditions.

As a result, industrial customers increasingly require switches featuring:

• Industrial-grade hardware design
• Wide operating temperature ranges
• DIN-rail or wall-mount installation
• Gigabit Ethernet connectivity
• SFP fiber uplink interfaces
• Redundant power inputs
• Ring network redundancy
• Layer 2 / Layer 3 management
• VLAN and QoS functions
• Network monitoring and diagnostics
• Industrial cybersecurity features
• PoE/PoE+ power delivery
• Fiber-optic communication for long-distance links

These requirements are particularly important for factories, substations, railway systems, intelligent transportation, surveillance systems, oil and gas facilities, renewable-energy installations and other critical infrastructure.

Smart Manufacturing Drives Industrial Ethernet Adoption

The development of smart factories is one of the strongest drivers for Industrial Ethernet switch demand.

Modern production facilities increasingly connect:

PLC → Industrial Ethernet Switch → HMI → Industrial PC → Sensors → Robots → Cameras → Edge Computing → Cloud Platform

This architecture allows production data to be collected, transmitted and analyzed in real time.

High-resolution machine-vision cameras, robotic systems, automated guided vehicles (AGVs), industrial sensors and edge-computing systems are generating significantly more network traffic than traditional automation systems.

This is increasing demand for Gigabit and multi-Gigabit Industrial Ethernet switches, particularly in production cells and industrial aggregation networks. Market research indicates that Gigabit Ethernet currently represents a major portion of Industrial Ethernet switch demand, while 10 Gigabit adoption is expected to expand as industrial vision and edge-computing workloads increase.

Managed Industrial Ethernet Switches Gain Importance

Industrial customers are increasingly moving beyond simple unmanaged switches toward managed networking solutions.

Managed Industrial Ethernet switches can provide functions such as:

• VLAN
• QoS
• STP/RSTP/MSTP
• ERPS or industrial ring redundancy
• Port mirroring
• Link aggregation
• IGMP Snooping
• SNMP
• Web-based management
• Network diagnostics
• Fault alarms
• Traffic monitoring
• Access control

These functions allow network administrators to monitor industrial networks, isolate network segments and quickly identify communication problems.

According to the 2026 Industrial Ethernet Switch market analysis, managed switches represented approximately 68.75% of market share in 2025, while Layer 3 platforms are projected to experience particularly strong growth through 2031.

Fiber Optic Connectivity Becomes Increasingly Important

Fiber connectivity is another important requirement for industrial networks.

Copper Ethernet is convenient for short-distance connections, but industrial facilities often contain long cable runs and areas with significant electromagnetic interference.

Industrial fiber switches can provide:

Industrial Switch → SFP → Fiber Backbone → SFP → Industrial Switch

Fiber networking offers:

• Long-distance transmission
• High bandwidth
• Strong electromagnetic interference immunity
• Electrical isolation
• Reliable backbone connectivity
• Reduced signal degradation over long distances

For large factories, transportation infrastructure, energy networks and outdoor industrial applications, fiber-based Industrial Ethernet networks can provide an effective backbone between different facilities or network cabinets.

PoE Creates New Industrial Networking Applications

Power over Ethernet is also expanding the application range of Industrial Ethernet switches.

Industrial PoE switches can simultaneously provide data communication and electrical power through Ethernet cables, reducing the need for separate power wiring.

Typical applications include:

• IP surveillance cameras
• Industrial cameras
• Wireless access points
• VoIP phones
• IoT gateways
• Access-control systems
• Industrial sensors
• LED displays
• Remote monitoring equipment

A typical deployment can be configured as:

Industrial PoE Switch → PoE Camera → Fiber Uplink → Control Center

This architecture is especially useful for factories, warehouses, smart transportation systems, security monitoring and outdoor industrial sites.

Industrial Cybersecurity Becomes a Key Purchasing Requirement

As industrial equipment becomes increasingly connected, cybersecurity is becoming an important factor in Industrial Ethernet network design.

Industrial networks are no longer isolated systems. PLCs, SCADA systems, industrial PCs, sensors and cloud platforms increasingly communicate through Ethernet networks.

This creates demand for switches that support network segmentation, access control, traffic management and monitoring.

Market analysis points to cybersecurity requirements, including IEC 62443-related considerations and regulations such as the EU NIS2 Directive, as factors encouraging organizations to adopt more capable managed networking equipment.

For industrial switch manufacturers, cybersecurity is therefore becoming increasingly important alongside traditional requirements such as temperature tolerance and network redundancy.

Ethernet-APL Expands Industrial Networking into the Field Level

Process industries such as oil and gas, chemicals, pharmaceuticals and energy are also driving the development of Ethernet-based field networks.

Ethernet-APL enables Ethernet communication to extend further into process automation environments and provides access to field-device data and diagnostics.

NAMUR's 2026 guidance highlights Ethernet-APL implementation, network planning, redundancy, installation and operation as important areas for process-industry deployment.

In 2026, IEC TS 63444:2026 Edition 2 was also published, covering Ethernet-APL and Ethernet-SPE port profiles, including long-distance communication, intrinsic-safety applications and power delivery over the same two-wire connection.

Large-scale testing in 2026 has further demonstrated multi-vendor Ethernet-APL interoperability involving process-control systems, field devices, switches and network infrastructure.

These developments indicate that Ethernet technology is continuing to move deeper into industrial field-level applications.

Key Industrial Ethernet Switch Applications

Future Demand for Industrial Ethernet Switches

The industrial networking market is moving toward a combination of higher bandwidth, greater reliability, stronger cybersecurity and easier network management.

Future Industrial Ethernet switch products are expected to increasingly incorporate:

Gigabit Ethernet + 10G Uplink + Fiber + PoE + Industrial Redundancy + Layer 2/Layer 3 Management + Network Security

At the same time, the continuing transition from fieldbus to Industrial Ethernet provides a long-term replacement and expansion opportunity. HMS Networks' 2026 analysis projects approximately 7.7% average annual growth in newly installed industrial network nodes over the next five years, with migration from remaining fieldbus installations contributing significantly to the expansion.

For equipment manufacturers and system integrators, this creates demand for a broad range of Industrial Ethernet switches, including unmanaged industrial switches, managed Layer 2 switches, Layer 3 switches, PoE switches, SFP fiber switches, DIN-rail switches, redundant-ring switches and high-port-count industrial aggregation switches.

Conclusion

The Industrial Ethernet switch market is being driven by the convergence of smart manufacturing, Industrial IoT, automation, edge computing, machine vision, fiber networking, PoE and industrial cybersecurity.

As factories and critical infrastructure become increasingly connected, industrial networks require not only higher bandwidth but also greater reliability, redundancy, security and operational visibility. Industrial Ethernet switches are therefore evolving from simple connectivity devices into an important component of the overall industrial digital infrastructure.

For industrial automation manufacturers, system integrators and network solution providers, the growing adoption of Industrial Ethernet creates continued demand for rugged, managed, fiber-capable and application-specific industrial switching solutions.
