XF2B
For FPC
Rotary Backlock Connector (0.3-mm Pitch, Dual Contact)
Rotary Backlock Mechanism
with 0.3-mm Pitch
• Wide molding wall on the rear bottom of the connector allows
greater freedom in board design.
• Dual 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.
RoHS compliant
