Why Choose the WAGO 852-303 Industrial Managed Switch?

The WAGO 852-303 is a powerful industrial managed Ethernet switch designed for advanced industrial networking applications requiring high reliability, redundancy and network management capabilities. As part of the professional WAGO 852 Managed Switch series, it combines robust industrial construction with extensive Layer 2 management features for demanding automation environments.

Featuring eight Fast Ethernet copper ports and two Gigabit fibre optic SFP slots, the switch enables secure and reliable communications between PLCs, HMIs, industrial computers, remote I/O devices and production systems. Advanced management features including VLANs, SNMP, RSTP, IGMP Snooping and web-based configuration provide complete control over network performance and diagnostics.

With a wide 12-60 V DC power input range, redundant power supply support, relay-based diagnostics and industrial-grade environmental protection, the 852-303 is ideal for mission-critical industrial Ethernet infrastructures. Although now discontinued, it remains widely deployed in industrial automation networks worldwide.

Advanced Managed Industrial Networking

Unlike unmanaged switches, the WAGO 852-303 provides comprehensive network management capabilities that allow engineers to monitor traffic, configure VLANs, implement network redundancy and optimise communication performance. These features are particularly valuable in complex industrial automation systems where uptime and deterministic communications are critical.

Its support for redundant ring topologies, fibre optic uplinks and advanced diagnostics makes it suitable for large-scale manufacturing facilities, infrastructure projects and process control applications where network failures cannot be tolerated.

Typical Applications

• Industrial automation networks.
• Factory-wide Ethernet infrastructures.
• Process control systems.
• SCADA communications.
• Utility and infrastructure installations.
• Machine building and OEM equipment.
• Industrial fibre optic networks.
• Critical manufacturing applications.
