The **W2RS-144-R2** is a specialized electronic component, typically categorized as a high-density, high-speed connector assembly or a specific backplane interface component used in telecommunications and server hardware. --- ### 1. Key Technical Specifications Based on standard nomenclature for this series, here are the primary technical characteristics: | Feature | Specification | | :--- | :--- | | **Total Pins** | 144 Pins | | **Configuration** | Dual Row (usually 72x2) | | **Mounting Type** | Through-hole (R-series often denotes Right Angle) | | **Contact Plating** | Gold or Gold Flash over Nickel | | **Housing Material** | High-temperature thermoplastic (UL 94V-0 rated) | | **Current Rating** | Typically 0.5A to 1.0A per contact | --- ### 2. Physical Design & Composition The "W2RS" prefix usually refers to a specific design architecture. Here is a breakdown of its physical parts: * **Insulator Body:** Made of Liquid Crystal Polymer (LCP) or PBT plastic to withstand lead-free soldering temperatures. * **Contact Pins:** Phosphor Bronze or Copper Alloy. These provide the electrical conductivity and spring force required for a stable connection. * **Tail Design:** The "R2" suffix often indicates a specific **Right-Angle** orientation with a defined tail length for PCB mounting, allowing the board to sit perpendicular to the interface. * **Shielding:** Often includes a metal outer shell or grounding pins to reduce Electromagnetic Interference (EMI) in high-speed data transfers. --- ### 3. Application Areas These parts are integrated into complex electronic systems where space is at a premium but high pin density is required: 1. **Networking Gear:** Used in routers and switches for daughter-card to backplane connections. 2. **Industrial Automation:** Serving as a bridge between PLC modules and I/O expansion boards. 3. **Medical Equipment:** High-reliability signal transmission in imaging or monitoring devices. 4. **Computing:** Linking expansion cards to motherboards in specialized server racks. --- ### 4.
