FPC connector with back-flip ZIF actuation
The 504740-3900 is a 39-position FPC connector from Molex, using a back-flip ZIF actuation mechanism for positive retention of the flex circuit.
Pitch and actuation for board fit
The 0.30 mm pitch and 39 positions place the 504740-3900 in the fine-pitch FPC segment; the back-flip ZIF lock secures the flex without requiring a secondary latch.
