Plug-in Screw Connector System for Printed Circuit Boards

120-M-257 5.00 mm (0.197 in) Spacing   -   4-44 poles Print this page

  • Header
  • Double level
  • Equiped with screw locking features that secure the plug and header together. This prevents accidental unplugging caused by human error, vibrations, impacts, wire pulling or gravity. Can be installed at any orientation with respect to horizontal.
  • Coding keys 120-K are available to prevent the insertion of the wrong plug into a header. These are usually field inserted but can be factory installed if required.
