T2050922101-007 is an HEE-046-M 47-92 heavy-duty connector insert designed for railway rolling stock applications and compliant with the EN45545 European standard for flame retardancy. This modular insert accommodates 46 poles with a current rating of 16A and voltage rating of 500V, enabling reliable transmission of signal, data, and power through a single connector. The insert meets R22 and R23 requirements at hazard level HL3, with materials approved for fire, smoke, and toxicity (FST) compliance per EN45545. Operating over a temperature range of -40°C to 125°C, it provides high flexibility for configuring railway connector systems used in traction converters, power distribution, and inter-car jumpers. The modular design enables time-saving assembly and reduces installation costs while maintaining reliable electrical connections in demanding railway environments.
