The Hirschmann MM20 – M2M29999EAHH Media Converter is a Hirschmann product for industrial network connectivity that addresses the challenges of transferring data between different network architectures and media in complex industrial environments. Thanks to Hirschmann’s extensive know-how, the device is characterised by a number of outstanding features.

I. Specification
Port: Support 10/100/1000Base-T adaptive rate, RJ-45 interface.
Ethernet: Support 10/100/1000Base-T adaptive rate, RJ-45 interface, with Cat5e and above cable transmission distance up to 100m, suitable for all kinds of Ethernet devices.

Optical Fiber: Multi-mode fiber port (50/125μm) with 1000Mbps transmission distance of 550m, suitable for short-distance high-speed scenarios within the plant; single-mode fiber port (1310nm) transmission distance of several kilometres for long-distance transmission, the interface is commonly used in SC, LC type, stable and convenient connection.

Electrical: Operating voltage 100 – 240V AC (50/60Hz), suitable for different industrial power supply, may also support DC 12V DC power supply, power consumption according to the design optimisation, reduce operating costs.

Physical: Compact size, following 1U (44.45mm) or 2U industrial standard height, suitable for cabinet installation. Metal casing is collision and extrusion resistant, with electromagnetic shielding, adapting to complex electromagnetic environments.

Protocol: Support Modbus TCP, PROFINET, EtherNet/IP and other common industrial Ethernet protocols to achieve the interconnection of different brands of equipment, reducing the difficulty of integration.

Performance Advantages
Data conversion
Fast and accurate: adopting high-performance chips and optimised circuits, fast processing of optical and electrical signal conversion, such as automotive production line sensor data, to ensure the timeliness.
Low latency: Optimised algorithms and architecture reduce data transmission latency to meet the high real-time requirements of robotics, motion control and other scenarios.
Network Adaptation

Rate Adaptation: Automatically identifies and matches devices with different rates, avoiding transmission problems due to rate differences and ensuring smooth network operation.

Media convergence: Fusion of optical fibre (long distance, high bandwidth, anti-interference) and Ethernet (widely used, good compatibility), to build an efficient network, such as optical fibre networking between workshops in the park, and Ethernet connection of equipment in the workshop.

Reliable and Stable
Industrial-grade design: Components are screened, resistant to temperature, humidity and dust, and the shell is dustproof and waterproof, able to withstand vibration and shock, suitable for steel mills, coal mines and other harsh environments.

Redundant design: some models have redundant power supply, the network supports link redundancy, to ensure the continuous operation of equipment and communication, suitable for electric power, chemical industry and other industries that require high reliability.
Security Enhancement

Network isolation: isolate different network areas to prevent network attacks from spreading, such as protection between different functional networks in power substations.
Security protocol: Support SSL/TLS and other encryption protocols to encrypt transmission data, prevent theft and tampering, and protect industrial data security.
