XF3B
Rotary Backlock Connector (0.3-mm Pitch, Dual-sided Contact)
For FPC
Rotary Backlock Mechanism with
0.3-mm Pitch and Low Profile of 0.9 mm
Wide molding wall on the rear bottom of the connector allows greater
freedom in board design.
Dual-sided contact model to enhance the contact structure of lower sided.
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
