B – Connectors for rail vehicle

Maximum 59 pole connector for power and control circuits on rail vehicles

B Series
B Series

The connectors, series B, have been designed especially for the demanding railcar environment. They are superbly suited for power and control circuits on road and rail vehicles alike.
An integrated interlocking circuit ensures that voltage is applied to the power circuit only when all covers are closed and all plugs have been mated or inserted into their respective dummy receptacles.


  • Rugged mechanical and electrical design
  • Universally usable connectors for power and control circuits
  • Easy replacement of components
  • Easy assembly resulting in short assembly times
  • Mechanically locking connector
  • Integrated interlocking circuit to protect personnel from contact with dangerous voltages


  • Connection of supply line and control cable of railway vehicles
