Junction Connector

  • A rectangular connector that enables signal branching.
  • 51 contacts of input signal can be branched to 102 contacts when output.
  • One-action fitting/removal and locking are possible by lever operation
  • Applicable wire size (0.2, 0.3, 0.5, 0.75, 1.25mm2)

Key features and benefits


  • Twin pin contacts are used on the plug side connector to branch the signal.
