Delta Electronics Domestic Connector Railway Traffic Certification Guide

Delta Electronics, as a global leading provider of RF, microwave, and millimeter wave connectors, offers a product line covering interfaces, adapters, and cable assemblies from DC to 67.5 GHz, widely used in aerospace, semiconductor, testing and measurement, and other high-demand fields. In addition, Delta provides isolated DC/DC power modules that comply with EN 50155 standard for rail and轨道交通 related equipment, specifically designed for drive control, power supply monitoring, and communication systems of rail transit systems.

Certification focuses of rail transit connectors
The certification requirements for connector and related electrical components in the rail transit system are extremely strict, covering the following core aspects:
Environmental and Safety Certification
●EN 50155 Railway Application Standard: Ensures that the product can operate stably under high vibration, wide temperature range, and interference environment. Delta provides DC/DC modules with corresponding standard design, which have good vibration resistance, interference resistance, and temperature adaptability.
Electrical safety and compatibility testing: It is necessary to meet electromagnetic compatibility (EMC), insulation withstand voltage, dust and water resistance grade (IP), etc., to ensure the overall safety and reliability of the system.
Quality Management and Standard Process Certification
●ISO 9001 / AS9100: These quality system certifications reflect the enterprise's standardized control capabilities in design, production, and testing processes, ensuring consistency and reliability between connector batches.
●RoHS / REACH / ITAR and other environmental or export control certifications: applicable to meet global environmental regulations and special area export requirements.
Customization and Design Process Requirements

● The track system usually has special requirements for interface types, durability, and anti-corrosion and dust-proof capabilities. Delta provides connectors with high-frequency bandwidth, standard interfaces, and fine workmanship, suitable for customized designs with high reliability requirements in rail transit.

Domestic connector replacement should pay attention to the certification strategy
Design in accordance with EN 50155 and related protection and electrical safety standards.
Establish a comprehensive quality management system (such as ISO 9001/AS9100) and testing processes to ensure production consistency and traceability.
Apply for relevant environmental and export compliance certifications (such as RoHS / REACH / ITAR) to meet market access requirements.

Strengthen customized capabilities, including interface structure, material selection, electrical and mechanical durability, and environmental adaptability testing.

The rail transit industry has stringent certification requirements for connectors, including standard environmental adaptation, quality system, compliance certification, and customized design capabilities. Delta Electronics has mature products and certification experience in multiple high-end fields, providing a reference benchmark for the replacement of domestic connectors. If domestic manufacturers can catch up in these aspects and establish a complete system, they will have the potential to replace and compete in the market.
