0.5 mm pitch, 68-circuit ZIF FPC connector
The 505110-6891 is a 68-circuit member of Molex's FPC connector line, using a zero-insertion-force (ZIF) bottom-contact design at 0.5 mm pitch. The ZIF actuator locks the FPC in place without insertion force, and the bottom-contact arrangement places the contact beams on the PCB side, keeping the cable side clear.
Pitch and contact side drive the board fit
The 0.5 mm pitch sets the routing density on the PCB — the footprint matches the standard 0.5 mm FPC connector land pattern, and the bottom-contact orientation means the FPC pads face down toward the board. The 68-position count matches the conductor count on the FPC; the ZIF actuator eliminates the insertion force that could buckle a narrow-pitch cable.
