Network switches are the backbone of modern industrial Ethernet networks, functioning as high-performance data distribution nodes that connect multiple devices within a local area network (LAN). These managed and unmanaged switches operate at Layer 2 or Layer 3 of the OSI model, supporting protocols like PROFINET, EtherNet/IP, and Modbus TCP for deterministic communication in automation environments. Key technical specifications include port count (typically 5 to 24 ports), data transfer rates (10/100 Mbps Fast Ethernet or 1000 Mbps Gigabit Ethernet), PoE (Power over Ethernet) capabilities for powering devices like IP cameras and sensors, and industrial-grade features such as redundant power inputs (dual 12-48 VDC), DIN-rail mounting, and extended temperature ranges (-40°C to +75°C). Managed switches offer advanced functions like VLAN segmentation, QoS (Quality of Service), SNMP monitoring, and ring redundancy protocols (e.g., RSTP, MRP) to ensure network resilience and zero-packet-loss failover.
Industrial network switches are deployed in harsh environments including factory floors, process plants, power substations, and transportation systems. They are essential for connecting PLCs, HMIs, drives, robots, and I/O modules in distributed control systems (DCS) and SCADA networks. In automated production lines, switches enable real-time data exchange between sensors and controllers, while in building automation, they link HVAC, lighting, and security subsystems. Their ruggedized design with IP20 to IP67 protection ratings ensures reliable operation in dusty, humid, or vibration-prone settings.
Our portfolio includes unmanaged switches for simple plug-and-play connectivity, managed switches for network optimization and security, and PoE switches for powering end devices over Ethernet cables. Key article codes follow a structured format: e.g., EAN-SW-UNM-05 for a 5-port unmanaged switch, EAN-SW-MGT-08 for an 8-port managed switch, and EAN-SW-POE-04 for a 4-port PoE switch. These codes incorporate port count and switch type, allowing easy identification. Subcategories also include industrial media converters and Ethernet extenders for long-distance communication.
