TE Connectivity ‘s new range of inserts for heavy duty connectors comply with the EN45545 European standard on flame retardancy for materials and products in railway rolling stock. The new inserts from TE meet R22 and R23 requirement set on level HL3. They have an operating temperature range that extends from -40 to 125 degrees Celsius. The modular inserts provide customers with a high level of flexibility when configuring railway connector systems. They can be configured to hold anywhere from 1 to 216 pins and enable signal, data and power to be transmitted via one single connector.
