The Hirschmann MM3-2FXM2/2TX1 is a rugged industrial Ethernet switch module designed for mission-critical network infrastructure in harsh environments. As part of the Modular Managed Machine (MM3) series, this media converter combines 2 multi-mode fiber optic ports (100BASE-FX) with 2 copper 10/100BASE-TX interfaces, enabling seamless integration of legacy fieldbus devices into modern PROFINET architectures. The MM3-2FXM2/2TX1’s MICE Level 3 certification ensures reliable operation in cement plant environments with extreme dust and vibration levels.
Featuring Hirschmann’s patented HiVision management system, the Hirschmann MM3-2FXM2/2TX1 supports advanced network diagnostics and ring redundancy protocols (HIPER Ring) for millisecond-level recovery in steel mill automation systems. Its compact 45mm width allows dense installation in railway signal control cabinets, while the -40°C to +75°C operating range meets EN 50155 requirements for rolling stock applications. The module’s dual power inputs (24VDC/48VAC) provide flexibility for offshore wind turbine SCADA networks.

Key Features and Advantages:
Network resilience: The MM3-2FXM2/2TX1 achieves <50ms network recovery through HIPER Ring v2 technology, critical for blast furnace control systems requiring continuous data flow. Built-in IGMP snooping optimizes multicast traffic in video surveillance networks.
Industrial durability: Stainless steel M12 connectors with screw locking withstand 15g vibration (IEC 61373) in mining truck wireless access points. The conformal-coated PCB resists chemical corrosion in oil refinery Ethernet backbones.
Smart management: Web-based interface supports SNMPv3 encryption for secure remote monitoring of paper mill production lines. Port mirroring function enables real-time traffic analysis without disrupting operations.
Application Areas:
The Hirschmann MM3-2FXM2/2TX1 excels in:
- Process Automation: Fiber backbone for ABB AC800M DCS systems
- Transportation: Tunnel communication networks with EN 50121-4 compliance
- Utilities: Substation IEC 61850-3 compliant networks
- Discrete Manufacturing: Robot cell network segmentation
In food processing plants, the module’s IP30 protection prevents moisture ingress in washdown areas while maintaining 1Gbps uplink speeds. Power generation facilities utilize its Class I Division 2 certification for hazardous zone deployments. The ST fiber connectors enable reliable 2km connections between control rooms and remote I/O in LNG terminals.
