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.
