The **W2PP-122R-R** is a specific type of electronic hardware component, commonly identified as a **double-row, right-angle pin header**. These parts are foundational in Printed Circuit Board (PCB) design, acting as the male portion of a board-to-board or wire-to-board connection system. --- ### 1. Component Specifications Below is a breakdown of the technical characteristics typically associated with this part number: | Feature | Specification | | :--- | :--- | | **Connector Type** | Pin Header (Male) | | **Orientation** | Right-Angle (90-degree bend) | | **Number of Rows** | 2 (Double Row) | | **Pitch** | Usually 2.0mm or 2.54mm (check specific datasheet) | | **Total Pins** | 22 Pins (11 pins per row) | | **Termination** | Through-Hole (Solder) | | **Mounting Type** | Horizontal / Side entry | --- ### 2. Key Physical Parts The W2PP-122R-R consists of three primary physical elements: 1. **Conductive Pins:** Made of a copper alloy (like brass or phosphor bronze) and plated with **Tin** or **Gold**. These facilitate the electrical signal transfer. 2. **Insulator Body:** A high-temperature plastic (Thermoplastic, LCP, or Nylon) that holds the pins in place and prevents electrical shorts between them. 3. **Right-Angle Bend:** The pins are pre-bent at a 90-degree angle, allowing the connector to sit parallel to the PCB surface. This is ideal for slim enclosures or "daughterboard" stacking. --- ### 3. Functional Applications This component is widely used in various electronic sectors: * **Internal Interconnects:** Connecting two PCBs together in a "sandwich" or perpendicular configuration. * **Ribbon Cable Interface:** Acting as the mating point for female IDC socket connectors. * **Prototyping:** Often found on development boards (like Arduino or ESP32 shields) for peripheral expansion. * **Industrial Controls:** Used in PLCs or modular sensors where space-saving horizontal connectivity is required. --- ### 4.
