New bus connectors meet the high demands of railway technology

17-02-2021 | Provertha | Connectors, Switches & EMECH

Provertha has produced new D-Sub bus connectors specifically designed for communication in the two bus systems MVB and WTB of the Train Communication Network. The new connector types facilitate reliable, vibration-proof connection of MVB/WTB cables to the MVB and WTB interfaces. Through the development of the new connectors, the high demands of railway technology, above all vibration safety, were taken into account. This is why the company has furnished the connectors with a vibration-proof screw-type locking system at the MVB or WTB interface. The combination of the vibration-proof single-wire connection and the vibration-proof connection of the shielding and strain relief produces maximum functional and operational safety in the railway sector.


The new bus connectors enable bus wiring with T-functionality. This indicates that the bus connections stay intact even if the connector is disconnected from the interface module or a module fails. There are terminating resistors and measuring capacitors on the bus circuit board which are activated by solder bridges. Special PCB solutions with individual functions can be realised.


The connectors with IP 30 protection are offered as either pins or sockets and can be utilised in a temperature range from -20C to +70C. They are created for a mechanical life of 500 (PL1 according to CECC 75301-802) and 250 mating cycles (PL2 according to CECC 75301-802). For the various MVB and WTB cable connections, they are offered as a complete set comprising the respective crimp flange/sleeve combination. Customised versions are also provided on request, in which case – depending on the needed cable type – a validated flange-sleeve combination is also supplied. Moreover, special PCB solutions according to customer specifications are also feasible.
