  • Screw machine contacts, silver or gold plated
  • Sturdy metal/plastic shells: Impact resistant, UL compliant, long life
  • Sealed to IP69K when mated and IP67 when not mated, respectively
  • Functional threaded coupling
  • Electrical and mechanical characteristics to IEC 61984

Applications

  • Connection of supply line and control cable for automatic train protection systems installed in bogies of railway vehicles
  • Special connector for harsh industrial applications
