XF3A
For FPC
Rotary Backlock Connector (0.3-mm Pitch, Upper Contact)
On-board height 0.6 mm, the lowest
class profile in the industry.
Rotary Backlock Connectors with
0.3-mm pitch.
• Wide molding wall on the rear bottom of the connector allows greater freedom
in board design.
• Upper Contact
• 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
