TCN Connector Bus Rate 100Mbps M12 D-Code

WS Series Aviation Connectors Types, Materials, and Specs

Bus Rate Requirements for TCN Connectors

For the Train Communication Network (TCN), connectors must support a bus rate of 100 Mbps or higher. This ensures reliable, real-time transmission of control signals between carriages and Passenger Information System (PIS) data.

Recommended connector types include M12 D-code or WF series aviation connectors, which are compatible with TCN standards. These connectors help maintain signal integrity and meet the network's timing requirements, with a maximum acceptable delay of ≤10 ms.

Key Selection Criteria

• Data Rate: Verify the connector's rated bandwidth supports 100 Mbps or higher for TCN backbone and PIS links.
• Interface Compatibility: M12 D-code and WF series are designed for industrial Ethernet and TCN protocols; confirm the mating interface matches your equipment.
• Signal Delay: Ensure the complete link (connector plus cable) meets the ≤10 ms latency requirement for control and PIS signals.
• Environmental Fit: For carriage-to-carriage or underfloor runs, confirm the connector's IP rating and vibration resistance match the installation environment.

Application Boundaries

These connectors are suitable for TCN and similar industrial Ethernet networks where real-time data exchange is critical. They are not intended for high-power traction circuits or applications requiring a different coding or pinout. Always confirm the specific pin count and coding (e.g., D-code) against your device's mating connector before installation.
