What this 0.5mm FFC connector fits
The 1-1734742-8 is a vertical SMD FFC/FPC connector from TE Connectivity, 18 positions on 0.50mm pitch. It accepts 0.30mm thick flat flex cable with straight or tapered ends. The ZIF slide lock secures the cable without insertion force — the contact beam wipes the pad on closure, not on insertion. Rated 0.5A per contact at 50V, this is strictly a signal connector. The gold flash contact finish handles moderate mating cycles in clean, indoor environments. For repeated flex or corrosive atmospheres, step up to a thicker gold plating — but the flash grade keeps cost down for one-time assembly.
Pitch and footprint for the board layout
0.50mm pitch means the PCB pads sit tight — a 0.30mm FFC thickness is the max the contact beam accepts. The mated height above board is 0.163" (4.15mm), which works for low-profile enclosures where space above the connector is limited.
