40-Position, 0.50mm Pitch FPC Connector with ZIF Slide Lock
Bottom Contact vs Top Contact – 62684-402100ALF Comparison
The 62684-401100ALF uses bottom contacts, meaning the FPC conductor pads face down toward the PCB. The sibling 62684-402100ALF is identical in pitch, position count, height, and plating, but uses top contacts — the FPC conductor pads face up, away from the PCB. The choice depends on the FPC cable routing and the PCB pad layout; bottom-contact connectors are more common for direct board-edge routing where the cable bends away from the board.
FPC Cable Thickness and Actuator Details
Accepts FPC thicknesses of 0.30mm and 0.33mm — the contact beam is designed for that range. The beige housing and black actuator are visual cues on the line; the actuator material is glass-filled thermoplastic, matching the housing's thermal expansion profile during reflow.
