12-Position FPC Connector with ZIF Slide Lock
The 10051922-1210EHLF is a 12-position FPC connector from Amphenol ICC (FCI)'s VLL series, built for dense board-level signal interconnects. Its 0.50mm pitch sets the PCB footprint — each pad sits 0.50mm apart, which limits trace routing width between pads on the board. The connector accepts a 0.30mm-thick FPC and uses a zero-insertion-force (ZIF) slide lock to secure the cable without stressing the pads during insertion. Rated at 0.5A per contact and 50V, this connector is suited for signal-level duty — display interfaces, sensor links, or low-power data lines in portable or embedded equipment.
The contacts carry a 2.00µin (0.051µm) gold flash over a copper alloy base. At that thickness, the gold is a corrosion barrier for a clean, low-humidity environment — think consumer electronics or indoor industrial controls. The housing and actuator are molded from liquid crystal polymer (LCP) glass-filled, halogen-free material rated UL94 V-0. That flame rating satisfies equipment inside an enclosure where flammability is a safety requirement. The actuator is black; the housing is natural — a visual cue for orientation during hand assembly.
Board Layout and Solder Retention
Mounted surface-mount, right-angle, the connector sits 1.30mm above the board. That low profile keeps the FPC close to the PCB surface, useful for tight z-height budgets in stacked or clamshell enclosures. The 0.50mm pitch demands careful PCB layout: trace width between pads is typically 0.20mm to 0.25mm on standard 1oz copper. A four-layer board with a solid ground plane under the connector helps control impedance for any high-speed signals on the FPC.
