XF3B Rotary Backlock Connector (0.3-mm Pitch, Dual-sided Contact)

Rotary Backlock Mechanism with 0.3-mm Pitch and Low Profile of 0.9 mm For FPC

  • Wide molding wall on the rear bottom of the connector allows greater freedom in board design.
  • Dual-sided contact model to enhance the contact structure of lower sided.
  • Gold plated with an applicable FPC thickness of 0.2 mm.
  • Halogen Free (*)
    * OMRON uses the following standard to determine halogen-free construction: 900 ppm max. for Br, 900 ppm max. for Cl, and 1,500 ppm max. for Br+Cl.
