WAGO 852-2112 Industrial ECO Switch with Single Pair Ethernet
The WAGO 852-2112 Industrial ECO Switch is a 6-port unmanaged Ethernet switch combining four 10BASE-T1L Single Pair Ethernet (SPE) ports with two 10/100BASE-TX RJ-45 ports. It enables 10 Mbit/s Ethernet communication over shielded twisted-pair cabling at distances up to 1,000 m (3,280 ft) — roughly ten times the reach of conventional 100BASE-TX over Cat 5. Lever-actuated SPE connectors, a 12…48 VDC supply, a -40°C to +70°C operating range, and an IP30 metal housing make it well-suited to control cabinets, decentralized sensor networks, and as a drop-in replacement for DSL modems or short fiber runs.

What Is the WAGO 852-2112?
The 852-2112 is an industrial unmanaged Ethernet switch built specifically for the transition from conventional fieldbus and Cat 5 cabling to Single Pair Ethernet. Each of the four SPE ports communicates at 10 Mbit/s over a single shielded twisted pair, delivering Ethernet to remote sensors, actuators, and field devices at distances that exceed 100BASE-TX by an order of magnitude. The two RJ-45 uplink ports connect the SPE network to a standard 10/100 Mbit/s Ethernet backbone or controller.
The switch is plug-and-play. Auto-negotiation handles the RJ-45 ports automatically, and each SPE port defaults to automatic master/slave detection. When connecting to third-party SPE devices that don't support auto-configuration, an 8-position DIP switch lets technicians manually assign auto-mode and master/slave roles per port without software tools.
Key Features & Benefits
| Feature | What It Means in the Field |
|---|---|
| 1,000 m SPE reach | Connect decentralized sensors and edge devices over a single twisted pair without intermediate switches, fiber media converters, or DSL modems. Drives down per-port wiring cost on long runs. |
| Lever-actuated SPE connector | Female connector with lever (WAGO 2231-1103/327-000, included) terminates without tools and accepts solid, stranded, or ferruled conductors. Faster installation and rework than screw or IDC SPE terminations. |
| Reuses existing 2-wire cabling | 10BASE-T1L is engineered to run on legacy two-wire infrastructure (instrumentation cable, twisted-pair runs already in conduit), letting plants migrate to Ethernet-to-the-edge without pulling new cable. |
| DSL modem / fiber link replacement | Paired with the WAGO 852-1705 SPE Media Converter, the 852-2112 substitutes for short-range fiber and copper DSL links between buildings, machines, or remote enclosures — eliminating modems and SFP modules. |
| DIP-switch port configuration | An 8-position DIP switch sets each SPE port to automatic mode (default) or manual master/slave, supporting interoperability with third-party SPE end devices that lack auto-configuration. |
| Wide 12…48 VDC input | Accepts the same supply rail as most WAGO 750/753 I/O systems, PFC controllers, and 24 VDC industrial power supplies. Less than 5 W consumption keeps cabinet thermal load low. |
| -40°C to +70°C operating range | Approved for cabinets in unconditioned environments — outdoor enclosures, water/wastewater pump stations, food & beverage processing, and oil & gas surface installations. |
| Plug-and-play | No firmware setup, no IP address, no web interface. Power, connect, run. Ideal for OEM machine builders and integrators who don't want managed-switch overhead on the SPE leg of the network. |
How the 852-2112 Stands Out from Competing SPE Switches
Single Pair Ethernet hardware is still emerging in the industrial market. A few specific design choices differentiate the 852-2112 from the small set of competing SPE-capable switches and media converters:
| Differentiator | Why It Matters |
|---|---|
| 4 SPE ports in a single 31 mm housing | Most competing SPE-to-Ethernet products are single-port media converters. The 852-2112 aggregates four 10BASE-T1L drops into one DIN-rail device, cutting cabinet footprint and reducing the number of separately powered devices. |
| Lever-clamp SPE termination | Competing SPE terminations on the market typically use screw clamps, push-in only, or proprietary IDC connectors. Lever actuation supports tool-free termination of all standard conductor types and allows in-field rework without re-cutting the cable. |
| Freely selectable polarity on SPE ports | D+ and D- can be terminated in either orientation. Eliminates wiring errors at the field device and removes the need to color-match conductors. |
| Full -40°C to +70°C operating range | Some SPE devices on the market are rated only to 0°C or +60°C. The 852-2112 carries the same temperature spec as WAGO's industrial 852-series RJ-45 switches, suiting it to outdoor and process-industry installations. |
| UL 61010-2-201 listed (E175199) | Listed for industrial control equipment under the standard most North American panel builders specify. Many emerging SPE devices carry only CE/CB certification. |
| Per-port quality LED feedback | Each SPE port has a dedicated LNK/ACT LED that shows green for a normal 10 Mbit/s link, orange when the link is established but signal quality is degraded, and flickers green/orange during data transfer. Helps technicians diagnose marginal cable runs without test equipment. |
| Integrated DIN-rail adapter and grounding screw | No accessory bracket required. Functional ground can be made through the dedicated grounding screw or through the CAGE CLAMP® ground terminal, simplifying EMC-compliant installation. |

Typical Applications
| Application | How the 852-2112 Fits |
|---|---|
| Decentralized sensor networks | Bring Ethernet-capable smart sensors and IO-Link masters online over distances that exceed 100BASE-TX, without intermediate switches in junction boxes or remote enclosures. |
| Brownfield migration to Ethernet | Replace HART, RS-485, or proprietary 2-wire fieldbus runs with 10BASE-T1L over the existing twisted-pair cabling already pulled in conduit. |
| Building automation backbone | Connect HVAC controllers, lighting nodes, and metering devices on a single shared SPE infrastructure rather than parallel BACnet, KNX, and Modbus runs. |
| Process plant monitoring | Tank farms, pump stations, water treatment, and outdoor process islands — the -40°C to +70°C rating handles unconditioned cabinets, and 1,000 m reach covers most facility footprints without repeaters. |
| DSL modem & short fiber replacement | Combined with the 852-1705 media converter, the 852-2112 substitutes for VDSL modems and short multimode fiber links between buildings or machines, removing dedicated modem hardware and SFP modules from the BOM. |

Safety & Installation Notes
| Important Installation Requirements | |
|---|---|
| Open-type device | The 852-2112 is an open-type device. It must be installed inside an additional enclosure, cabinet, or electrical operations room providing protection against direct contact, UV, and pollution. |
| Functional grounding required | Ground via the dedicated grounding screw or the CAGE CLAMP® ground terminal. Do not operate without functional ground. |
| Qualified personnel | Installation and commissioning must be performed by qualified electrical specialists per EN 50110-1/-2 and IEC 60364. |
| EMC best practices | Ground the DIN rail; use shielded cabling for SPE and signal lines; route data lines away from VFDs and other high-emission sources; bond shielding at the cabinet inlet. |
| Twist data line up to the connector | For best 10BASE-T1L signal integrity over long runs, continue twisting the SPE wire pair as close to the female connector as possible. Insulate the shield with shrink tubing where needed before terminating to SHD. |
Frequently Asked Questions
Q: What is the maximum cable length on the SPE ports of the 852-2112?
Each 10BASE-T1L port supports up to 1,000 m (approximately 3,280 ft) over SPE-compatible shielded twisted-pair cable. The two RJ-45 100BASE-TX ports follow the standard 100 m Cat 5 limit.
Q: Is the 852-2112 a managed switch?
No. The 852-2112 is an unmanaged industrial ECO switch. It supports IEEE 802.3x flow control and Nway auto-negotiation, but has no web interface, VLAN, RSTP, SNMP, or Modbus TCP management. Per-port SPE master/slave settings are configured via DIP switch.
Q: Does the 852-2112 supply Power over Data Line (PoDL)?
No. The 852-2112 transmits data only over its SPE ports. It does not source PoDL on the 10BASE-T1L lines, and the RJ-45 ports do not support PoE. Powered SPE devices must be supplied by a separate 24 VDC rail or a PoDL-capable injector.
Q: Can I connect the 852-2112 to third-party SPE devices?
Yes. Each SPE port follows IEEE 802.3cg and interoperates with any compliant 10BASE-T1L end device. If the third-party device does not support automatic master/slave negotiation, set the corresponding port to manual mode on the DIP switch and assign master or slave to match.
Q: What's the difference between the 852-2112 and the 852-1705?
The 852-1705 is a single-port SPE-to-RJ-45 media converter for connecting one remote SPE end device to a standard Ethernet network. The 852-2112 is a 6-port switch that aggregates four SPE drops and provides two RJ-45 uplinks. Use the 852-1705 for point-to-point links and the 852-2112 when consolidating multiple SPE devices.
Q: Does the SPE port polarity matter?
No. The 852-2112's SPE ports have freely selectable polarity, so D+ and D- can be terminated in either orientation without affecting link establishment.
Q: Is the 852-2112 UL listed?
Yes. The 852-2112 is UL-listed under UL 61010-2-201 (industrial control equipment, ordinary locations), certificate E175199. It also carries CE, UKCA, and FCC marks and is RoHS-compliant with no exemption.
Q: What supply voltage does the 852-2112 require?
12…48 VDC, 5 W maximum. It runs from the same 24 VDC rail used by typical WAGO PFC controllers and 750/753 I/O nodes.
