The **FX1-5W6-R** is a high-performance, high-density rectangular connector component typically manufactured by **Hirose Electric (HRS)**. It belongs to the FX1 series, which is designed for board-to-board applications requiring robust connections and high pin counts. --- ### 1. General Specifications The FX1-5W6-R is essentially a **receptacle** (female connector) used in high-speed, multi-signal environments. | Feature | Specification | | :--- | :--- | | **Part Series** | FX1 (Board-to-Board) | | **Contact Type** | Receptacle (Female) | | **Pitch** | 1.27mm (0.050") | | **Number of Positions** | Variable (typically dictated by the "5W6" configuration) | | **Mounting Type** | Through-hole (Right Angle or Straight) | | **Termination** | Solder | --- ### 2. Key Electronic Features #### A. High-Density Pitch With a **1.27mm pitch**, this component allows for a high concentration of signals within a small footprint on the PCB. This is critical for modern telecommunications and industrial computing equipment where space is at a premium. #### B. Contact Reliability The "FX" series is known for its **ribbon-style contacts**. Unlike pin-and-socket designs that can be fragile, ribbon contacts provide: * Increased contact area. * Resistance to twisting and bending during mating. * Lower insertion forces. #### C. Signal Integrity The internal geometry of the FX1-5W6-R is optimized to handle high-speed data transmission with minimal crosstalk. It is often used in backplane or daughtercard arrangements where signal integrity is paramount. --- ### 3. Usage Context This part is commonly found in the following electronic assemblies: 1. **Industrial Controllers:** Connecting CPU boards to I/O modules. 2. **Medical Equipment:** High-density imaging or monitoring data paths. 3. **Telecommunications:** Base station switching hardware. --- ### 4.
