Overview

Overview 3
The 852-112/000-001 switch is an industrial unmanaged ETHERNET switch with 8
10/1000Base-TX ports. The ports of the industrial switch allow multiple segments to be
formed to reduce network congestion, and each user node can be assigned its own band-
width. The slim design with DIN rail adapter allows easy installation in the control cabinet
with high vibration and shock resistance. The automatic recognition of the transmission
rate (autonegotiation) as well as the automatic determination of the transmit and receive
lines (Auto MDI-X) enable simple plug & play operation and thus help to save costs and
time during commissioning.

3.1 Industrial ETHERNET Technology

The range of WAGO Switches ensures scalability of your network infrastructure with out-
standing electrical and mechanical characteristics. These rugged devices are designed
for industrial use and are fully compliant with the IEEE 802.3, 802.3u and 802.3x stan-
dards. They have power supply with a supply voltage range of 12 ... 48 VDC. Character-
istics such as auto-negotiation and auto MDI/MDIX (crossover) on all 10/100BASE-TX
ports are also realized.

3.2 Switching Technology

Industrial ETHERNET primarily uses switching technology. This technology allows any
network subscriber to send at any time because the subscriber always has an open peer-
to-peer connection to the next switch. The connection is bidirectional, i.e., the subscriber
can send and receive at the same time (full duplex). The targeted use of switching tech-
nology can increase real-time capability because the peer-to-peer connection prevents
collisions in network communication.

3.3 Autonegotiation

Autonegotiation allows the switch to detect the transmission rate and operating mode for
each port and the connected subscriber or subscribers, and to set them automatically.
The highest possible mode (transmission speed and operating mode) is set. Autonegotia-
tion is available to ETHERNET subscribers connected to the switch via copper cable.
This make the switch a plug-and-play device.

3.4 Autocrossing

Autocrossing (MDI/MDI-X, "Medium Dependent Interface") automatically reconfigures the
receive and transmit signals for twisted-pair interfaces as needed. This allow users to use
wired and crossover cables in the same manner 1:1.
