It terminates with solder to the board in a right-angle surface-mount orientation, keeping the mated FPC parallel to the PCB at a 1.90 mm height above board. The flip-lock actuator secures the FPC without a secondary latch; the beige housing and black actuator colour code the connector on the board. Tin contacts with 39.4 µin (1.00 µm) finish are rated for 25 mating cycles — suited to low-service-life applications where cost per connector matters more than cycle count. ## Solder retention and flip-lock keep the FPC seated The flip lock actuates without tools; the FPC inserts with the contacts on the bottom side, and the lock presses the cable flat against the contact beams. The phosphor bronze contacts are tin-plated, which limits the mating cycle life to 25 but keeps the per-unit cost lower than gold-plated alternatives.","metaTitle":"Molex 5052781933 – Easy-On FS19 FFC Connector, 19 Pos","metaDescription":"Molex 5052781933 FFC/FPC connector, 19 positions, 0.5 mm pitch, right-angle SMT, tin contacts, flip lock, UL94 V-0.
