XF3A Rotary Backlock Connector (0.3-mm Pitch, Upper sided Contact)

On-board height 0.6 mm, the lowest class profile in the industry. Rotary Backlock Connectors with 0.3-mm pitch. For FPC

  • Wide molding wall on the rear bottom of the connector allows greater freedom in board design.
  • Upper sided.
  • Gold plated with an applicable FPC thickness of 0.12 mm.
  • Halogen Free (See note.)
    Note: 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.
