Network switch Wago 852-111 — 5-port Fast Ethernet (10/100), full duplex, 18–30 V DC

Wago 852-111 is a compact 5-port Fast Ethernet (10/100) network switch designed for reliable wired connectivity in small LAN segments, industrial environments and office networks. It features five RJ-45 ports that support full-duplex operation and conform to IEEE 802.3/802.3u/802.3x standards. The device accepts a DC input voltage range of 18–30 V and includes a MAC address table with capacity for 2000 entries. Its form factor allows rack mounting to integrate into existing network infrastructure.

Advantages

The switch provides straightforward basic switching functionality with five RJ-45 Ethernet ports, ensuring stable 10/100 Mbps connections for connected devices. Full-duplex support and compliance with common Ethernet standards promote interoperability with a wide range of network equipment. A MAC address table sized for 2000 entries helps manage multiple connected devices and reduces unnecessary traffic. The DC input range of 18–30 V suits many industrial power systems and the unit's rack-mount capability simplifies installation in telecom or network cabinets.

How to use

Install the Wago 852-111 into a suitable rack space or place it on a stable surface according to available mounting options. Connect each network device to the switch using appropriate Ethernet cables (Cat5 or higher) and ensure correct RJ-45 seating. Supply the switch with a DC voltage in the 18–30 V range from a compatible power source. The device operates as a plug-and-play unmanaged switch, so connected devices will negotiate speed and duplex automatically according to their capabilities and the switch's supported standards.

Recommendations

For stable performance, use shielded or unshielded twisted-pair cables of appropriate category for required distance and environment, keep firmware or system monitoring tools (where applicable) up to date, and provide adequate ventilation in rack installations to maintain operating temperatures. In industrial installations, ensure the DC power supply is properly grounded and protected against surges.
