Plug-in Screw Connector System for Printed Circuit Boards

110-A-115 3.50 mm (0.138 in) Spacing   -   2-22 poles Print this page

  • Type 110-A-115 plug is equipped with locking flanges and screws which provide secure mating with headers. This design feature eliminates the possibility of accidental disconnection and requires a screwdriver to connect and disconnect the plug from the header.
  • Plug
  • 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.

    Elevator style of wire clamping mechanism ensures reliable wire contact
  • 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. These coding keys are visible from the exterior, through slots in the header. Correct keying requires the removal of corresponding keying nibs from the 110-A plugs.
