The **W2PP-321R-R2** is a specialized electronic component, typically categorized as a **Wire-to-Board (WTB) Connector** or a header assembly used in power delivery and signal transmission. It is frequently manufactured by brands like **Wellco** or specialized industrial connector suppliers. --- ### 1. General Specifications This part is designed for high-density electronic assemblies where space-saving and reliability are critical. | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Male Header / Connector | | **Pitch Distance** | Often 2.0mm or 3.0mm (depending on specific series) | | **Pin Configuration** | 2-Row (Dual Row) | | **Total Pins** | 32 Pins (as indicated by the "32" in the part number) | | **Mounting Type** | Through-Hole (THT) or SMT (Surface Mount) | | **Material** | High-Temperature Thermoplastic / Brass with Tin or Gold Plating | --- ### 2. Breakdown of Part Number Nomenclature While manufacturers vary slightly, the code generally follows this logic: * **W2P:** Refers to the series type (often **W**ire-to-Board, **2**-row, **P**lug/Header). * **321:** Indicates the circuit count or physical configuration (32-pin layout). * **R:** Represents a **Right-Angle** orientation (the pins exit the connector at a 90-degree angle to the PCB). * **R2:** Usually denotes a specific **Revision** or **Packaging** code (e.g., Tape & Reel for automated assembly). --- ### 3. Electrical & Mechanical Properties * **Current Rating:** Typically ranges from **1A to 5A** per pin depending on the wire gauge and housing used. * **Voltage Rating:** Usually rated for **250V AC/DC**. * **Operating Temperature:** -25°C to +85°C (Standard industrial grade). * **Locking Mechanism:** Often features a friction lock or a positive latching mechanism to prevent accidental disconnection due to vibration. --- ### 4. Common Applications Due to its high pin count and compact dual-row design, this part is found in: 1. **Industrial Controllers:** Connecting internal PCB modules to external sensors. 2. **Consumer Electronics:** Power distribution inside gaming consoles or appliances. 3. **Automotive Aftermarket:** Used in display units and infotainment wiring harnesses. 4. **Medical Equipment:** Internal signal routing between diagnostic boards.
