F4S Narrow Pitch Connectors

Panasonic Industry F4S Narrow Pitch Connectors are 0.4mm connectors that provide board-to-FPC connections. These connectors feature a space-saving width of 3.6mm to contribute to the miniaturization of target equipment. The F4S connectors provide strong resistance to adverse environments, a simple tactile-feel lock structure to ensure superior mating/unmating, and gull-wing type terminals to facilitate automatic mounting inspections. Panasonic F4S Narrow Pitch connectors are ideal for compact, portable devices such as cellular phones, DVCs, digital cameras, and more.
