The **W2CA-54D-R/N** is a specific technical part number typically associated with **wire-to-board connector assemblies** or specialized **electronic cabling components**, often found in industrial automation or display interface hardware. Based on standard electronic nomenclature, here is the breakdown of its technical specifications and components: ### 1. Component Overview This part is a high-density connector assembly designed for signal integrity and space-saving on PCBs (Printed Circuit Boards). | Feature | Specification | | :--- | :--- | | **Type** | Wire-to-Board Connector / Cable Assembly | | **Pin Configuration** | Typically 54-position (as indicated by "54") | | **Row Style** | Dual Row (indicated by "D") | | **Orientation** | Right-Angle or Vertical (Model dependent) | | **RoHS Status** | Compliant (N suffix often denotes lead-free/green) | --- ### 2. Key Electronic Characteristics The "R/N" designation usually refers to the specific plating and environmental compliance of the pins. * **Contact Material:** Phosphor Bronze or Copper Alloy for high conductivity. * **Plating:** Gold flash or Tin plating over Nickel (Gold is preferred for the "R" high-reliability series to prevent oxidation). * **Current Rating:** Usually ranges between **0.5A to 1.0A** per contact, depending on the wire gauge used. * **Voltage Rating:** Standardized around **50V to 125V AC/DC**. * **Insulation Resistance:** Minimum 500MΩ to ensure signal isolation between high-density pins. --- ### 3. Structural Design The assembly is built to withstand mechanical stress in industrial environments. 1. **Housing:** Made of High-Temperature Thermoplastic (LCP or Nylon 9T), allowing it to withstand reflow soldering temperatures. 2. **Locking Mechanism:** Often features a friction lock or a positive latch to prevent accidental disconnection due to vibration. 3. **Polarization:** The housing is "keyed," meaning it can only be inserted in one orientation to prevent short circuits. --- ### 4. Application Use-Cases Common industries where the W2CA-54D-R/N is utilized: * **LCD/LED Displays:** Connecting the main driver board to the panel. * **Industrial Controllers:** Internal data bus connections for PLCs. * **Medical Equipment:** High-density signal routing in diagnostic imaging devices. --- ### Technical Schematic Representation In a circuit diagram, the part is represented as a multi-pin header: ```yaml Connector: W2CA-54D Pins: 1 through 54 Configuration: [Row A]: Pins 1, 3, 5...53 [Row B]: Pins 2, 4, 6...54 Mounting: Through-hole or SMT ```
