XF3C Rotary Backlock Connector (0.25-mm Pitch, Dual-sided Contact)

0.25-mm Pitch with Dual-sided Contact and Rotary Backlock Mechanism. For FPC

  • Wide molding wall on the rear bottom of the connector allows greater freedom in board design.
  • Dual-sided contact.
  • 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.
