The **W2PP-119N-R** is a specific electronic hardware component, typically categorized as a **pogo pin connector** or a spring-loaded terminal. These parts are widely used in electronics for temporary or high-cycle connections, such as charging docks, battery terminals, or testing fixtures. --- ### 1. General Specifications While specific manufacturer datasheets may vary slightly, components in this series generally follow these technical parameters: | Feature | Description | | :--- | :--- | | **Type** | Spring Loaded Connector (Pogo Pin) | | **Mounting Type** | Through-hole (PTH) or Surface Mount (SMT) | | **Contact Material** | Brass or Copper Alloy | | **Plating** | Gold over Nickel (for high conductivity and corrosion resistance) | | **Spring Material** | Stainless Steel or Music Wire | | **Durability** | Typically 10,000 to 100,000 cycles | --- ### 2. Key Electronic Characteristics The "Electronic Parts" aspect refers to how the pin behaves within a circuit. * **Current Rating:** Usually rated between **1A and 3A**. Because pogo pins rely on a spring mechanism, high current can cause internal heating if the contact resistance is too high. * **Contact Resistance:** Typically very low, often **<30mΩ**. This ensures minimal voltage drop across the connection. * **Operating Voltage:** Generally used for low-voltage signals or DC power (up to 12V or 24V). * **Stroke/Travel:** The pin has a "working stroke" (the ideal compression distance) and a "full stroke" (the maximum the pin can be pushed). --- ### 3. Applications The W2PP-119N-R is commonly found in the following electronic environments: 1. **Consumer Electronics:** Smartwatches and TWS earbuds for charging interfaces. 2. **Industrial Testing:** Used on ICT (In-Circuit Test) fixtures to probe PCBs without soldering. 3. **Modular Connections:** Connecting two PCBs together in a stack where easy disassembly is required. --- ### 4. Component Structure A standard pogo pin consists of three main parts: 1. **Plunger:** The moving part that makes contact with the target. 2. **Barrel:** The housing that holds the spring and plunger. 3. **Spring:** Provides the force required to maintain electrical contact. ```mermaid graph LR A[Plunger] --- B[Spring] B --- C[Barrel/Base] C --> D[PCB Soldering Point] ``` ---
