The 5047543900 is a 39-position FPC connector from the Molex BackFlip / Easy-On LA75 504754 series, built for high-density board-edge interconnect at a 0.012" (0.30mm) pitch. Gold-plated contacts on both top and bottom sides mate with a 0.20mm-thick tabbed FPC, and the flip-lock / backlock actuator secures the cable without needing a secondary latch. The housing is black LCP rated UL94 V-0, and the actuator is gray glass-filled nylon.
What the 0.2A rating means for your circuit
Rated 0.2A per contact at 50V — this is a signal-only connector. The 0.30mm pitch and thin 0.10µm gold flash limit current capacity; don't plan to carry power through it. The 10 mating cycles confirm it's designed for one-time assembly or occasional service, not repeated field disconnect.
