To safeguard every journey, the European Committee for Standardization (CEN) and the European Committee for Electrotechnical Standardization (CENELEC) jointly developed the EN45545 fire protection standard, which sets strict and comprehensive requirements for the fire safety of railway vehicles and components.
Overview of the EN45545 Standard
EN45545 is a fire protection standard for railway materials and components.
It defines requirements for fire resistance, smoke density, and toxicity under fire conditions, covering everything from interior materials to electrical equipment.
For connectors, compliance with EN45545 means enhanced safety, reliability, and suitability for harsh railway environments.
M12 Connectors in Railway Applications
M12 connectors are widely used in modern railway systems.
Different coding types (A-code, D-code, X-code) define pin layouts and serve specific signal, data, or power transmission needs:
A-code (4, 5, 8 pins) – For sensors (temperature, speed), actuators, DC power, and low-voltage signals.
D-code (4 pins) – For Industrial Ethernet, onboard IP cameras, and passenger information systems (Fast Ethernet, 100 Mb/s).
X-code (8 pins) – Designed for high-speed Ethernet up to 10 Gb/s, supporting backbone networks, HD video surveillance, and infotainment systems with full EMI shielding.
At STA Electronic, our M12 A, D, and X-coded connectors are fully compliant with EN45545, ensuring safe and reliable operation in railway environments.
M12 Connectors & EN45545 Compliance
STA Electronic’s M12 connectors are developed with EN45545 requirements as the baseline, featuring:
Ingress Protection: IP67 rating, ensuring dust- and water-resistance in harsh outdoor conditions.
Environmental Durability: Resistant to vibration, shock, temperature fluctuations (-40°C to +85°C), humidity, and dust.
High-Speed Data Transmission: Supporting Fast Ethernet, Gigabit Ethernet, and up to 10 Gb/s for industrial communication.
Mechanical Reliability: Over 500 mating cycles with secure locking/unlocking mechanisms for consistent performance.
Clear Coding: Standardized A/D/X coding with marking and color differentiation for safe and correct mating.
Certified Testing: Verified through mechanical, environmental, and electrical performance tests.
By investing in advanced materials and technologies, STA Electronic ensures that its M12 connectors not only comply with EN45545 but also drive innovation in railway connectivity.
STA Electronic: Commitment to Railway Safety
Achieving EN45545 certification marks another milestone in STA Electronic’s commitment to railway fire safety and product reliability.
