XF2B Rotary Backlock Connector (0.3mm-Pitch, Dual-sided Contact)

Rotary Backlock Mechanism with 0.3 mm-Pitch For FPC

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

Discontinuation Date: Mar. 31, 2018
