Industrial managed M12 Ethernet switch MOXA EN50155 8 ports

MOXA EN50155 is an industrial managed M12 Ethernet switch with 8 ports designed for rail and heavy-vehicle applications that require EN50155 compliance. It provides managed switching functions for network control and reliability in harsh conditions, using rugged M12 connectors that resist vibration and moisture. The switch supports traffic management and diagnostics needed for transportation networks, industrial automation and remote equipment connectivity, while fitting into space-constrained installations where robust electrical and mechanical performance is required.

Advantages

The device combines EN50155 compliance with managed switching features to deliver predictable network behavior, centralized configuration and detailed status monitoring. Its M12 connector interface offers secure cable connections in high-vibration and wet environments, and the compact, industrial-grade housing is engineered for extended operation under temperature and shock stresses typical in rail and heavy-vehicle systems. Management capabilities allow VLAN segmentation, priority handling and fault detection to maintain service continuity.

Suitable for

• On-board train networks and signaling equipment
• Heavy vehicles and mobile machinery communications
• Industrial automation and remote I/O aggregation
• Video surveillance and passenger information systems in transport
• Edge networking in harsh or constrained installations

Key specifications

• Ports: 8 Ethernet ports with M12 connectors
• Switch type: Managed Layer 2 switching with traffic control functions
• Standards: Designed for EN50155 operational requirements
• Mounting and enclosure: Rugged industrial housing suitable for vibration and shock environments

How to use

Install the switch in an appropriate rack or cabinet location and secure it according to the vehicle or equipment mounting requirements. Use certified M12 cables to connect field devices and uplinks, ensuring correct sealing and locking of connectors. Configure network parameters using the switch management interface to set VLANs, QoS and port behavior. Verify power input matches the system supply and apply necessary grounding. Monitor status and logs to confirm link integrity and to troubleshoot connectivity or performance issues.

Recommendations

Place the switch where it is protected from direct debris and excessive heat, and regularly inspect M12 connections for corrosion or looseness. Keep firmware updated and validate configuration backups after changes to minimize downtime. For critical transport applications, combine redundant topologies and clear labeling of ports to speed maintenance and fault isolation.
