The connector is designed in accordance with the specifications of the international railway standard UIC 541-5. It adds to the range of our well-proven connectors for the railway industry. This heavy-duty connector is designed to ensure the electrical connection within a train for the electropneumatic brakes (EP brakes) as well as the bypass of an electropneumatic emergency brake.
Both systems have functions which overlap through their control and monitoring elements. They are fed by a common electrical cable that runs the length of the train. Integrated in the receptacle is a switching element as pilot contact which is used for feedback signalling a plug being mated. whereas the end of train is signalled by means of a pin contact in the dummy receptacle.

Features

  • Feedback plug being mated: via an optional switching element integrated in the receptacle shell
  • Feedback end of train: via a pin contact in the dummy receptacle
  • Rugged mechanical and electrical design
  • Receptacle shell with metal handle
  • Connector for power and signal transmission

Applications

  • DMUs, EMUs, rail cars and passenger coaches: Power and signal transfer for electropneumatic brakes as well as electropneumatic emergency brake override (EBO)
  • Freight wagons: Power and signal transfer for electropneumatic brakes
