Vivotek AW-IHT-0602 Industrial EN50155 PoE+ Switch

Vivotek AW-IHT-0602 Industrial EN50155 PoE+ Switch

The Vivotek AW-IHT-0602 is a ruggedized industrial Ethernet switch purpose-built for railway and transportation applications requiring EN50155 compliance. With four M12 PoE+ ports and two additional Fast Ethernet ports, this switch delivers reliable power and connectivity to IP surveillance, security cameras, and field devices in the harshest environments—including mobile platforms subject to vibration, shock, and extreme temperature fluctuations.

Key Features

• Four M12 PoE+ Connectors: Industrial-grade M12 4-pole D-coded connections rated for 30W per port, delivering combined PoE power budget of 120W across the network
• EN50155 Certified: Meets railway equipment standards for electronic devices in mobile and stationary applications
• Six Fast Ethernet Ports: Four M12 PoE+ ports plus two additional M12 Fast Ethernet ports for flexible network architecture
• Redundant Power Inputs: Dual 24–56VDC power supplies with automatic failover for mission-critical uptime
• Rugged Metal Enclosure: IP40-rated housing with wall-mount design, engineered for shock and vibration resistance
• IEEE 802.3at/af Compliant: Full PoE Plus standard support with auto-detection of powered devices
• Comprehensive Protection: Over-current and circuit-shorting safeguards on all PoE outputs

Technical Highlights

The AW-IHT-0602 operates across a -40°C to 75°C temperature range, making it suitable for both heated and unheated rail cars, outdoor trackside installations, and transit stations. Backplane throughput of 1.2 Gbps supports up to 148,000 packets per second at 100 Mbps, ensuring minimal latency for real-time video and critical control signals. The switch maintains a 128 KB buffer with store-and-forward transmission to handle network congestion gracefully.

Auto-MDI/MDI-X and auto-negotiation eliminate manual cable configuration. LED indicators for Power, Relay, LAN, and PoE status provide at-a-glance network diagnostics. An M12 alarm relay output (1A@24VDC) enables integration with external warning systems and safety interlocks.

Applications

• Railway rolling stock and wayside infrastructure
• Public transit systems (buses, trams, metro)
• Port and terminal automated surveillance
• Industrial vehicle fleet monitoring
• Mission-critical security networks in transportation hubs

Power consumption is rated at 126W under full load. Optional railway-grade DC-DC converters (RSD-100D-24) are available for integration with vehicle electrical systems.

The AW-IHT-0602 distinguishes itself through mandatory EN50155 certification and M12 connector architecture—critical for railway deployments where connector reliability directly impacts safety and uptime. The 120W PoE budget supports up to four high-power thermal or PTZ cameras simultaneously, a substantial allocation for mobile surveillance. Redundant power inputs and rugged construction address the reality of railway environments: vibration, temperature swings, and power instability are constant challenges.

The store-and-forward design and 1.2 Gbps backplane provide headroom for video traffic spikes without frame loss. For integrators deploying surveillance across rolling stock or mixed fixed-mobile infrastructure, this switch eliminates the complexity of device-level power management and cable reliability issues inherent to non-industrial switches.
