The Wafer connector and the FIT connector differ significantly in design, application, and connection method. Wafer connectors typically have a flat rectangular design, mainly used for board-to-board or board-to-wire connections. Their compact design makes them suitable for space-constrained applications. They are commonly found in consumer electronics, automotive systems, and industrial equipment, where their ease of insertion and removal meets the demands of frequent connections or replacements. In contrast, FIT connectors (Flexible Interconnect Technology) are specifically designed for flexible interconnection applications, typically connecting flexible printed circuit boards (FPC) or flat flexible cables (FFC) to printed circuit boards (PCB). FIT connectors are better suited for applications requiring high reliability and flexibility, such as medical devices and mobile devices. They usually employ zero insertion force (ZIF) or low insertion force (LIF) connection methods to reduce wear and ensure a secure connection. Therefore, Wafer connectors are more suitable for standardized, compact connections, while FIT connectors excel in applications requiring flexible connections and high durability.
